The Gravely TractorThe Gravely Tractor is powered by theair - cooled, four - cycle, one - cylinderGravely Engine, which is rated conserva-tively at 6.6HP at 2600 RPM. The Trac-tor Wheels are driven through an all-gear, automotive - type, Transmission,

while front-mounted power attachmentsare powered by a direct drive.

FUEL

Use a good regular gasoline, not high-test. Fuel Tank capacity is approxi-mately two gallons, but to allow for ex-pansion, do not fill over 1% gallons.

TIRES

Tire size is 4.00x8, 16-inch outside diam-eter. Infla e the Tires io maximum pres-sure of 18 pounds.

REPAIRING FLAT TIRE. Engage bothOperating Levers (See Figure 2) to pre-vent he Tractor from moving. Be surethe Tube is deflated fully by removingits Valve Core.

Then loosen, but do not remove, thethree hex-bead cap screws in the Rim.Raise the Wheel off the ground, and re-move it from the Tractor by removingthe three hex-head cap screws.With the Wheel removed remove the

three remaining bolls to separate theRim and expose the Tube. Repair theTube with any commercial patching kit.

IN TALLING NEW TIRE. Follow theabove procedures, making sure the Tirebeing replaced is deflated fully beforeyou remove its Wheel from the Tractor

LUBRICATION

Filling the Chassis to its five-pint capa-city with motor oil lubricates both theEngine and Transmission. Do not usetransmission oil or grease. We recom-mend these oils:

ummer-SAE 30 or SAE IOW-30.

Winter-32· F. or below) SAE 20Wor SAE lOW-30.

OIL LEVEL. Routinely check the oillevel with the Dipstick, 1 in Figure 1,

before starting. Be sure the Tractor islevel.'

ADDING OIL. Add oil by removingthe Oil Filter Cap, 2 in Figure 1. Stopwhen oil reaches the FULL mark on theDipstick, Note: Allow enough time forthe oil to seek its own level before check-ing to see if the FULL mark has beenreached. This prevents over-filling theChassis.

OIL FILLER AP. Periodically checkthe "breather" type on Filler Cap. Washit in a solvent when needed.

OIL HANGE. During the break-in

period, the first 40 hours of operation,change on every 20 hours. Then changeoil every 60 hours under normal condi-tions, or every 40 hours under verydusty or dirty conditions and during

extended operation. Drain used oil byremoving the Oil Drain Plug, the bottombolt in he left Tractor Axle Housing', 3

in Figure 1. In replacing this Nylon-plugged bolt in the botton bolt hole,be sure the special sealing washer is inplace.

OIL FILTER. For the best results,recommend changing the Oil FLlter eve80 hours, although satlsfactcry resulmay be obtained by changing it eve150 hours, maximum, or once a seasowhichever is shorter.

The Oil Filter, 4 in Figure 1, is dsigned to be unscrewed by hand 11'its Bracket. However, to break the seit may be necessary sometimes to uslight force.

When attaching a new Filter, do novertighten, as this may damage the sea

ote: Do not change the connectionin any way when replacing the Oil Filte

OIL PRES R. A glance at the OPressure Gauge when starting ells ywhether oil pressure is correct.' Ifpressure is not correct, stop the Enginimmediately and call your GraveldeaJer.

AIR CLEANERNext to proper lubrication, care of tAir Cleaner is vital to Engine life-sovital, in fact, that the Gravely Warrantydoes not apply to parts worn or damagebecause of improper Air Cleaner care.

The "Double-Guard" Air Cleaner', 5Figure 1, makes it virtually impossiblto damage the Engine with dirty awhen the Cleaner becomes clogged widirt particles, this blocks the flow of ao the Engine, thereby stopping the E

gine.

However, as the Cleaner becomeclogged, the resulting air loss decreaseEngine power. Thus, to prevent this patially or completely-clogged conditionfollow these cleaning instructions ever

ATTACH ING TOOLSAll Gravely power attachments are at-tached to the front of the Tractor by fourbolts. See instructions on Page 7.Also, several non-power attachments

are secured to the front of the Tractorin the same way. See instructions start-ing on Page 20.Other non-power attachments are se-

cured to the rear of the Tractor by theGravely Rear Hitch. See instructions onPage 23.

START ING THETRACTORWhether you have he Strap (manual)

Starter or Electric Starter, before start-ing your Tractor check to insure thatthe:

o Opera ing Levers are in neutral;

o Attachment Clutch Lever (or At-tachment Clutch Control) is at the OUTposition;

o Valve on the Sediment Bowl (theglass bowl by the Carburetor) is open;

• Throttle is depressed approximatelyhalf-way;

o Ignition Stop Switch (if you havean older Tractor so equipped) is ON;and,

o An Attaehmen or Attachment BossCover is secured to the front of theTractor by four bolts.

NORl\'lAL TARTING. On Tractorswith the Strap Starter:

1. Turn the Pulley shown in Figure 3coun ter-clcckwise (opposite the directionof the arrow on the Pulley) as far aspossible.

2. Attach the Strap to the Pulley(place the hole in the Strap over the pi.nin the Pulley groove) and wind the Strap

onto the Pulley in the direction of thearrow.

3. Pull the Strap hard and fast. Chokeas required.With the Electric Starter, simply press

the Starter Button with your foot. Chokeas required.Note: In proper working order, the

Engine should start with one or twoattempts (a few more may be necessary

in cold weather). If it doesn't, chethe "Trouble Shooting" section on Pa3 to find and correct the trouble. Dotamper with the Carburetor-this wonly serve to complicate things, for evwith the Carburetor out of adiustmethe Engine will start.COLD WEATHER S ARTING. C

weather starting troubles usually canavoided if you:

o Make sure the proper weight oi

used. Oils heavier than those recomended will stiffen at low temperaturethus making starting more difficult.

TRACTORO'PERAT ION

When starting the Engine have boperating Levers in neutral and thetachment Clutch Lever at the OUT potion (or the Attachment Clutch Contpushed forward fully).

If you have the optional eight-speeTransmission, the Range Selection Leshould be in the position for the ranin which 'he Tractor will be operatinitially.

After starting, decrease Engine sp

to a fast idle.



'NGAGING WHEEL. To put theTractor in motion, first move the InsideOperating Lever into high or low. Thenmove the Outside Operating Lever intoforward or reverse. Use a smooth, evenmotion in shifting the operating levers.Depress the Throttle to the desiredspeed.

Note: With the Inside Operating Leverin high or low and the Outside OperatingLever in neutral, the Tractor will not

move. Both Level's must be engaged be-fore the Tractor will move.

ENGAGING POWER ATTACHMENT.Before attempting to put a power attach-ment in gear, be sure the Tractor isstopped, with both Operating Levers inneutral and the Engine running at idlespeed.

To engage the attachment" move theOutside Operating Lever forward justenough to make the Engine "pull down"slightly. At the same time, move tbe At-tachment Clutch Lever to the IN posi-tion (or pull the Attachment Clutch Con-trol fully to the rear).After the attachment is engaged, in-

crease Engine speed to about half-throt-tle, and move the Inside Operating Leverto high or low. Put the Tractor in rno-tion by moving the Outside OperatingLevel' to forward or reverse,

DIENGAGlNG POWER ATTACH-ME T, If you have the AttachmentClutch Control, the attachment may bedisengaged while the Tractor is in mo-tion simply by pushing the Clutch Con-trol forward fully,If the Tractor has only the Attach-

ment Clutch Lever, stop the Tractor andcut the Engine off. Be sure the attach-ment is not moving before you attemptto move the Lever to the OUT position.

STANDAItD TRANSl\fi ION .. The

Standard Transmission has four speeds-high and low in forward and high andlow in reverse. These speeds controlboth ground speed and attachment RPM,with low gear having approximately 75pet' cent of the speed obtainable in highgear.The Inside Operating Lever may be

shifted between high and low while theTractor is moving (See caution, Page12). The Outside Operating Lever shouldbe shifted between forward and reverseonly when the Tractor is stopped or rnov-ing at a very slow speed.Choice between high and Jow gear will

be governed mainly by actual operatingconditions. Generally, difficult jobs suchas snow blowing, plowing', cultivating.and heavy mowing should be done in

low gear, while easier jobs such as lawnmowing can be done in high gear.

EIGHT-SPEED TRANSl\USSION. Theeight-speed Transrnission features a two-speed axle that can be shifted betweenhigh and low ranges. in each axle rangethe Operating Levers can be shifted be·ween forward and reverse and betweenhigh and low. This gives the Tractorfoul' speeds forward and four reverse.

ShHting the axle between high andlow ranges controls only the Tractor'sground speed. Shifting the Inside Oper-ating Lever between high and low pro-vides a further control over groundspeed, as well as attachment RPM. Withthe axle in low range, Tractor groundspeed is 50 per cent slower than withthe axle in high range.To shiH between axle ranges: Stop the

Tractor (see caution below) and cutEngine speed to an idle. Keep the in·side Operating Lever in high or low,but move the Outside Operating Leverto neutral. Move the Range SelectionLever to high or low range. Move theOutside Operating Lever back and forthslightly, and then engage it in forwardor reverse.

Individual jobs will dictate the corn-bination of axle range and gear to beused, In general, low axle range shouldbe used [or plowing, cultivating, snow

blowing, heavy mowing, and other jobswhere a slower ground speed is neededto give the attachment longer to do itsjob. High axle range generally is satis-factory for mowing and other lawn jobs.

BRAIUNG. The Outside OperatingLever may be used as a "brake" whenyou must stop suddenly or wish to stopmomentarily while going down an in-cline, Quickly move the Lever out offorward, pass through neutral, and applypressure at the reverse position-enoughpressure to stop the forward motion ofthe Tractor, but not enough pressure tolock the Lever fully in reverse.

01'ERATING IN REVERSE. Whenoperating the Tractor in reverse, we rec-ommend that you keep your hand on theOutside Operating Lever. Thus, shouldyou fall or get pinned against a wall orfence, you can stop the Tractor imme-diately by moving the Lever to neutral.See "Safety Reverse" on Page 4.

OTHER POINTS. Don't slip the Clutch,If you find the ground speed of the

Tractor too fast for the job,. don't easethe Outside Operating Lever in and outof gear to maintain the required groundspeed, Instead, shift to a lowe.r gear (onthe Standard Transmission to low gear;on the eight-speed Transmission, to lowaxle range). Or if you can't shift anylower, take a smaller bite-one in whichthe attachment can do the job with theTractor fully in gear. Repeated Clutchclipping causes undue wear and thusshould be avoided.

• Keep the bolts and nuts tight. Hava regular time to go over the Tractoand tighten them.

• Don't try to help the Gravely. Rmember, it's much stronger than yoare. But powerful as it is, it still takeorders from you. Just give your Gravelthe "guidance" it needs-and leave thhard work to it.

STOPPING THEENGINETake the attachment out of gear, movthe Operating Levers to neutral, and cEngine speed to an idle. Then depresthe Ignition Stop Button (on the endthe right 'I'ractor Handle). On oldeTractors with the Ignition Slop Switchpull to stop; if not Switch-equipped, d

press the Magneto Stop Button.

TROUBLE-SHOOTINGThe Gravely Engine, like any internacombustion engine, occasionally mafail to start. Following are the morcommon malfunctions and the necessarycorrective measures.

'TIEL TROUBLES. Check to see if th

• Fuel 'I'ank contains fresh fuel.• Fuel Tank Cap venting system

clear.• Fuel Cut-off Valve (on the Sedimen

Bowl) is open. Turn eounter-e'lockwis

to open,• Fuel Jine is clear. Close the Cut-o

Valve, remove the Sediment Bowl, anreopen the Valve. If fuel flows, the linis clear; if not, check the Neoprene Fu

Hose and fittings.• Carburetor is getting fuel. With th

Sediment Bowl and fuel line intact, clothe Cut-off Valve. Drain any fuel rmaining in the Carburetor by removingthe plug from the bottom of the Caburetor. Open the Cut-off Valve. If fudoes not flow out the bottom of the Caburetor', there is an obstruction in. thCarburetor. Call your Gravely dealer

IGNITION TROUBLES. Check to s

if the:• Spark Plug is shorted out bJ' co

Tractors) is ON.• Ignition Stop Button (or Ignitio

Stop Switch, on older Tractors)shorted out. To test, remove the cabfrom the M.agneto Stop Button andtempt to start the Engine.



CARBURETOR AND AIR CLEANERTROUBLE. A flooded Carburetor orclogged Air Cleaner may keep the En-gine from starting, To check, first dis-

connect the Air Cleaner Hose and holdit pointing downward.If fuel drains from the Hose, the prob-

lem is Carburetor flooding (another in-dication is that the Carburetor will bewet). To correct, allow he Hose todrain complet ']y, reconn ct

it0 the

Carburetor, and start the Engine.

Note: Carburetor flooding is morelikely to occur on older Tractors havinga long, curved Air Cleaner Hose. Cur-rent models with a shorter, straighterHose seldom have this difficulty.If fuel does not drain from the Hose,

the problem most likely is a clogged AirCleaner. To check, xamine the Element.[f needed, clean the Air Cleaner and re-connect the Hose to the Carburetor.

A DJU STM EN 'TS YO U

SHOULD KNOWFollowing are common adjustme.ntswhich most users can perform readily.SPARK PLUG. The. Autolite T~·lO

Sparlc Plug, which gives a me~lumspark should have its gap set to .033-mch.CL' Tell ROD. Thc need for Clutch

Rod adjustment is indicated by slippagewhen the Opera ling Levers are lockedin position. To ~djus.t, lighten the loci,nuts 1 and 2 111 FIgure 4, until theClut~h Rod Springs are compressed ,f\lllyas each Lever is locked into position,The Tractor may "creep" a little on oc-casion even in neutral, but this does notindicate the need for Clutch adjustment.

SAFETY REVERSE. The Outside Op-

eratirig Lever can be adjusted so thatit must be held in reverse, instead ofbeing locked in this position. Whenadjusted this way, the Tractor auto-matically goes into neutral when pres-sure is released from the L Vel'. To per-form this adjustment, run the lock nutson the lower end ot the Outside ClutchRod up to a point where the Lever can-not be locked into reverse; when ad-justed properly, the Lever returns toneutral when pressure is released.

EIGHT· PEED TRAN MIS 10LINKAGE. The Toggle Spring (locatedby the Range Selection Lever) ceca-sionally may require adjustment bytightening the hex nuts on the ToggleRod until the Spring is compressed to15/16-incb.

The Clutch Springs, 3 and < 1 in Figure4, occasionally may need to be adj usted,With the Range Selection Lever en-gag d fully in high or low range, movethe hex nuts on the Spring Rod untileach Spring is compressed to 21f~ inches.

ARB RETOR. If absolutely neces-sary to adjust the Carburetor, followthese instructions:

1. Screw the Jet Adjustment Valve (abrass T·valve) in until it is snug. Donot force or screw it tightly.

2. Back the Jet Adjustment Valve off2% turns.'3. Start the Engine and depress the

Throttle half-way, Arter the Enginewarms up, begin screwing the Jet Ad-justment 'Valve in slowly. As

Figure 4

the Engine slows down, stop and ba

the Valve off 1 h turn.

4. Screw the Idle Air Jet AdjustmenValve (a slotted-head screw withspring wound around it) all the waythen back it off l~ turns," StartEngine and allow it to idle. ScrewIdle Air Jet Adjustment Valve in unthe Engine begins to buck, spit, or bafire, Then back the Valve off lJ s tu

If the Engine still runs roughly. backoff another 'A ! turn.Special instructions for Gravely C

buretors are available from the factoPlease give the make and model of yCarburetor when writing for instruction

VAL VE. Adjust the Valves owhen the Engine is cold. RemoveValve Cover Cap, shown in Figure 5,use a 7/16·inch open-end wrench 10just Tappet clearance to .012·inch. Tis a self-Iock lng Tappet."

FAN BE.LT. Fan Belt tension isjusted by moving the Fan Belt Pull(the smaller Pulley at the rear otTractor) up, to increase tension,down, to decrease tension. The Fan Bis in proper adjustment when moderapressure applied at its mid-point wdeflect it approximately %·inch.

STOR ING THETRACTORAlthough the Gravely has attachmentsfor year-round use, perhaps you do notplan to use it during the winter. If so,it is important that you store your Trac-tor according to the following directions:

TORAGE. Clean the Tractor thor-

oughly with kerosene and a stiff brush.This, and following storage procedures,should be done in a well ventilated roomand away from open flame. Then:1. Drain the Fuel Tank (by removing

the Sediment Bowl, next to the Carbure-tor).

2. Drain the Chassis (see "OilChanges"), flush with kerosine, and re-fill with SAE 30 or SAE IOW-30. Runthe Engine two minutes to distribute heoil, but do not get the Engine hot.

3. Remove the Spark Plug and putI I < ! pint of lhe same oil as used in theTractor in the Cylinder. Turn the En-gine over by hand (by turning he FanBelt Pulley at the rear of the Tractor)

several times. Leave the Piston on topdead-center and replace the spark plug.

4. Store in a dry place, with theWheels jacked up off the floor. If theTractor must be stored outside, we rec-ommend use of the Tractor Cover de-scribed on Page 6.

DUAL W HEELSDual Wheels are useful in situationsrequiring extra traction, as in use of the'is-inch Snowplow for bulldozing, haulingheavy loads in the Transportation Cart,and mowing terraces and slopes withGravely mowing attachments. DualWheels allow you 0 mow slopes assteep as 60 per cent. Dual Wheels alwaysshould be used when the Steering Sulkyis used.

To attach:

1. Remove the three hex-head cap

screws that bold the Wheel Rim to theTractor.

2. Attach the Spacer to the insideWheel Rim and Tractor by lnserting thethree long cap screws provided throughthe holes in the Spacer. Tighten thesescrews firmly. Be sure the Spacer reocess with the small indentation fits overthe inside Wheel's Tire Valve.

3. Use the three short cap Screws

which were removed initially to attachthe outside Wheel Rim to the Spacer.No lubrication is required.

SICKLE MOWERThe Sickle Mower is a rugged, dependa-ble mower that makes the toughest weedand brush cutting easy. Swivel actionallows the Blade to follow the groundcontour to insure a clean cut.Blades longer than the standard 42

inches are available from your Gravelydealer. Blades are provided with three-

inch sections for heavy mowing and two-inch sections for finer mowing.Using the Dual Wheels or Extension

Axles, the Sickle Mower can cut slopesas steep as 60 per cent. See Pages 5 and 6.

LUBRICATIONCheck the Drive Assembly oil level everyfour hours of operation by removing theOil Level Plug, 1 in Figure 11. If oilruns out, the oil level is all right; if not,

oi! must be added.To add oil, remove the Oil Filler Plug,

2 in Figure 11 and pour oil through theOil Filler Hole until oil begins to runout the Oil Level Hole. Replace bothPlugs before mowing.Use SAE 140 in lhe Drive Assembly.To lubricate the Universal Joint, re-

move the Grease Plug, 3 in Figure 11,

and fill about half-full with GeneralPurpose Grease.Because the Universal Joint needs

lubrication only occasionally, you may. pre er this method: with the Mower de-tached from the Tractor, remove theSafety Clutch and tour bol s, 4 in Figure11 which hold the lower column to theUniversal Housing and slip the Housingpartly off. Then apply General PurposeGrease generously to the Universal Joint(coal it all over with one to I'll inches ofGeneral Purpose Grease). Reassembleall parts, making sure you tighten firmlythe large nu which holds the Safety

Clutch.

ADJUSTMENTS

To insure satisfactory performance,perform the following adjustments asrequired:BOLT. Although the Sickle Mower

is bui.lt and balanced carefully, it is stillsubject to some vibration. Periodicallylighten all nuts and bolts, doing this atmore frequent intervals when doinghe~l\ry cutting. Note: The Gravely

Triple-Purpose Wrench, available fromyour Gravely dealer is required for theActuating Lever ut.CLIP _ The Clips which hold the

Knife to the Guide Bar should be ad-justed frequently to prevent cut matterfrom "bunching" and causing improperfeed-off. When in proper adjustmentthe Clips should allow the Knife to sJid~back and [or h easily (with the pressureof a finger and thumb). The Clipsshould hold the Knife in firm contactwith the Shear Plates, but should notcause binding. To adjust knock theClips down gradually wi h' gentle tapsfrom a light hammer.

WIVEL A TION. To increase swivelaction (allowing the M wer to followthe contour of the ground), loosen the

bolts, 6 in Figure 11. When these bol tsare tightened firmly, the Mower is heldin a rigid position. The bolts should betight enough so the Guide Bar will holdits position until lowered, but looseenough for the Guide Bar to follow thecontour of the ground.G ARD. Always keep the Guards

7 in Figure 11, in alignment by tappingthese with a light hammer until theKnife Sections lie flat on the ShearPlates of the Guards. Keep the GuardBolts lightened securely.

CARE OF THE KNIFE

For best performance, keep the KnifeSections sharp, To remove the Knife forsharpening, remove the Kn iIe BracketScrews, 5 in Figure 11, and slip the

Knife out either side. Grind the Knife

Figure 11

Sickle Mower.....-+

Sections along the same bevel as grouoriginally. When. replacing the Knmake sure the Knife Bracket Screwstightened firmly.Note: It is good practice always

have an extra Knife, already sharpenewhich you can put on the Mower whneeded. This way you can always havesharpened Knife in reserve. The GraveSickle Grinder (see Page 10) can be pchased from your Gravely dealer, or

will sharpen your Knife for a smbarge,

No lubrication is required forKnife while in operation, as juices frweeds and grass will furnish sufficilubrication. However, to prevent ruWIpe the Knife and Guide Bar withthin coat of light oil after operatinWhen the Mower is to be stored forperiod of time, clean it thoroughlyapply General Purpose Grease to allpainted parts.

OPERATING HINTS

Always mow at a normal walking spwith the Tractor in low gear. Excessispeed will exaggerate the Mower vib11On, causing nuts and bolts to beco

loose much faster than normal.• Ii excessive vibration is encountere

check to see if the Wearing Tip (onend of the Actuating Lever) is wornmissing, or if the Bracket is worn badif so, your Gravely deaJer can replathese parts for you,• If cut grass or weeds begin colle

ing on the Mower instead of feeding-properly, check the alignment ofGuards and Knife Sections, as wellsharpness of the Knife Sections...If this does not correct the impr

er feed-off, make sure one end ofMower is not dragging up already-cmaterial. This is the result of taking

small a "bite."" Another cause of improper feed-

is a rusty or gummy Mower. Alwa

keep itclean.• Finally, the improper feed-off m

be caused by improper adjustment of

Safety Clutch. See page 7.

LUBRICATION

Check the oil level in the Gear Housingevery four hours of operation, by re-moving the Oil Level Plug, 1 in Figure12. If oil runs out, the oil level is allright; if not, oil must be added.

To add oil, remove the Oil Filler Plugapproximate location shown by 2 i~

Figure 12, and pour oil through the OilFiller Hole. . Stop when oil begins torun out the ail Level Hole. Replace botbplugs before mowing.

Use SAE 140 in the Gear Housing.

Use General Purpose Grease every 10bours in the grease fittings on the CasterBrackets, Caster Wheels, and SwivelCasting 3 in Figure 12.

Use General Purpose Grease every 10hours in the grease fitting on eachSpindle Assembly. Note: The SpindleAssembly grease fitting is vented to makeit impossible to over-lubricate the Spin-dle Assembly. While greasing, if youobserve grease coming out the vent thismeans simply that the Spindle Assem-

bly is loaded to capacity with grease.

BEtTS

The Mower has two Belts: the right Belt(right, as you stand at the Handles),which drives the center and right Blades,and the left Belt, which drl ves the leftBlade. Proper adjustment of the Beltsis vital-if too tight, the Belts will wearexcessively; if too loose, the Belts willslip, causing the Mower to skip over areaswithin its swath. Also, if the Belts arenot in proper adjustment, the Bearingsand Belts will run hotter than normal,

BELT ADJ STl\IENT. The Belts arein proper adjustment when the Moweris delivered. Loosening is seldom re-quired, except when replacing a Belt.However, from time to time you willneed to tighten the Belts; this is indi-cated by the Mower skipping over areas

within its swathThe left Belt is adjusted at the leftSpindle Assembly, access to which isgained by removing the machine screwswhich hold the left Belt Guard to theDeck. The right Belt can be adjusted ateither the ri,ght or center Spindle Assem-blY, access to which is gained by remov-ing the machine screws which hold thecenter and right Belt Guards to the Deck,

We recommend that adjustment of theright Belt be made at the right SpindleAssem bly inifia l l y ; only if a ddi tiori O Il ad-justment is needed should you adjust atthe center Spindle Assembly

To tC: In adjusting the Belts it ispossible to pull a Spindle Assembly farenough from its proper position to causeits Blade to strike the adjacent Bladewhile mowing. When you have adjustedthe Belts, always rotate tile Blades byhand to make sure there is no Blade in -terferen cc and to ins u re there is Su tfi-dent overlap to keep [rom missing areas,especially on turns.

The procedure for tightening eachBelt is the same-the Spindle Assemblyis moved Irom the Main Drive Pulleyas follows (Refer to Figure 14 [or partsidenti.fication) :

l. Loosen the four nuts which holdthe Spindle Assembly and Dust Shieldto the Deck. It is not necessary to holdthe bolts onto which these are screwed,as they are locked to the underside of

the Deck.

Use SAE 140 in the Gear Housing.

Use General Purpose Grease oeca-sionally in the grease fittings of theSwivel Casting.

SWIVEL ACTION

A:OJUSTMENIT

Swivel action of the Drive Assembly isregulated by the Swivel Adjustment Boltand Nut, 3 in Figure 16,. Loosening theAdjustment Nut increases swivel action;tightening it decreases swivel action.When using the 30·inch Rotary Mower,

Leaf Mulcher, and Leaf-Away, thereshould be sufficient swivel action toallow the attachment to follow theground contour with its own weight.When using the Chain or Circular Saw,loosen the Adjustment Nut, turn theDrive Assembly to the desired angle,and tighten the Nut firmly.

ROTARY MOWER

To attach the 30·inch Rotary Mower tothe Model 106 Drive Assembly, detachthe Drive Assembly from the Tractorand turn it upside down so the Oil Filler

Plug is on the bottom.

Next, set the Mower Hood in placewith the Rear Fender (the taller of thetwo Fenders) facing the rear of theDri ve Assembly.

Place a bolt and plain lh·inch washerthrough each ct the six holes in theHood and Gear Housing flange, with the

bolt heads on the under side of the Hood.Place a lock washer and nut on the endof each bolt showing through the GearHousing flange and tighten each nutsecurely,

Place the Cellars and Blade onto theRotor Shaft in any order you wish. (See.,Cu tting Heigh t Adj ustmen t," below.)Be sure the counter-bored sides of theCollars face the Blade. Tighten the nuton the end of the Rolor Shaft securely,Note: The G r a vel y Triple-PurposeWrench, available from you!" Gravelydealer, is required for the nut on theend of the Rotor Shaft. It also must beused for tile Actuating Lever Nut onthe Sickle Mower, and Tine Shaft Nuton the Rotary Cui tivator.

Use a file Dr grindstone to sharpen theBlade. Try to follow the same bevel as

the originally-sharpened cutting edge,although the precise degree of bevel isnot critical.

F ENDE R AOJUSTM ENT

When mowing short weeds and lawns,the Front Fender (the smaller Fender)must be on front of the Mower Hood,and the Rear Fender (the larger Fen-del') on the rear.

However, when mowing high, heavybrush, or thick, tough grass of consider-able height, better mowing results willbe obtained by removing the Front Fen-del', and replacing it with the optionalChain Guard. See below.

EMPTYING POUCH

To empty the Pouch, simply unsnaPouch from the Chute, unhook ithe Pouch Support, and unzip. Coare easily shaken out.

Note: For use in large areas,as college grounds, we recommendchase of additional Pouches. Sfilled pouches may be taken in a

to where the lea ves are to be burn



OPERATING HINTS

Q Operate the Leaf-Away with the

Tractor in high gear at all times.• Stoppage caused by leaves and de-

bris blocking the Chute is detected bycollapse of the Pouch. To correc , keepthe Blowers operating at high speed andwork the Chute Cleaner Poker with avertical motion into the Chute.

• Although the Leaf-Away will func-tion effectively in most cases with onlyone Mower Blade Blower, we recom-mend use of both Blowers, especiallywhere leaves and debris have a highmoisture content. Also, we r commendyou clean your lawn often enough toprevent leaves from becoming packeddown by heavy rain or SI10W, as leavesin this condition increase th chance ofChute clogging.

CHA IN SAWBefore attaching the Chain Saw to theDrive Assembly, make sure you havethe proper Chain Saw Bracket for your

Drive Assembly. Drive Assembly Mod-els 52 through 58, having a Gear Hous-ing diameter of 2% , inches, require theChain Saw Bracket, Part Number CS-IOI.Drive Assembly Models 58-A and 185,having a Gear Housing diameter of 3 Y 4inches, require the Chain aw Bracket,Part Number CS-IOI-L A ConvertingCollar, Part Number CS-331, may bepurchased from your G ra vely dealer toadapt he Chain Saw Bracket CS-IOl-lfor use with Drive Assembly Models 52through 58.

ATTACHING TO

DRIVE ASSEMBLY

Attach the Chain Saw to the Drive As-sembly as follows:

L Remove the nut and Collars fromthe Rotor Shaft.2. Loosen the Bracket Clamp boll, 1

in Figure 17, until the Bracket, 2 inFigure 17, will slip onto the Gear Hous-ing (it may be necessary to wedge theBracket to make it Ilt). Line the loweredge of the Bracket even with the loweredge of the Housing-not with the fixedCollar. Tighten the Bracket Clamp Bollto lock the Bracket in place.

3 _ Loosen the Swivel Adjustment Bolt(on the Drive Assembly) and rota e theBracket until the Guide Bar, 3 in Figure17, points straight up. Then tigh ten theSwivel Adjustment Bolt.4. Loosen the Clamp Bolts (which

hold the Bracket together) enough toallow the Guide Bar to slide back and

forth easily. Put the Chain on the GuideBar, bringing it through the Bracket.

5 _ Slip the Ih-inch Collar onto theRotor Shaft, with the counter-bored sidetoward the end of the Shaft. Slip theSprocket onto the Shaft and put theChain around the Sprocket. ote: OnDrive Assemblies 58, 58-A, and 185, whenviewed from the end of the shaft, theSprocket revolves counter-clockwise; onthe other Drive Assemblies, the Sprocketrevolves clockwise, Be sure the cuttingteeth move in the same direction as theSprocket,

6 _ Place the lf4-inc11 and 7fs-inch Col-lars on the Shatt, making sure the ccun-ter-bored sides face the Sprocket. Put theflat washer on the Shaft and tighten thenut firmly.

CHAIN ADJUSTMENT

Turn the Chain Adjusting Screw, ap-proximate location on other side ofGuide shown by 4 in Figure 17, clock-wise to increase Chain tension. Whenthe Chain is under proper tension, it willbe slightly loose on the Guide Bar, butnot loose enough to permit it to comeout 0 its slot when grasped firmly andpulled away strongly from the Guide

Bar. Excessive tension will cause theChain to "burn" the Guide Bar.

ANGULAR ADJUSTMENT

To change the position of the Chainaw in relation to the Gear Housing,

loosen the Bracket Clamp Boll and turnthe Sa w to the desired position, tilentighten he Bracket Clamp Boll.

To rotate the Drive Assembly, loosenthe Swivel Adjustment Nut and movethe Drive Assembly to the desired posi-tion; then tighten the Nut,

Figure 17

OPERATING HINTS

Best results can be obtained with theChain Saw if you:

• Always swing the Saw sidewaysinto the tree, Jetting it. "feed' itself nat-urally by applying only light pressureto the Tractor Handles. Never braceyourself against. the Handles to force theSaw into the tree faster than it normallywould feed itself. To do. so will causeexcessive wear of the Chain and GuidBar, resulting in unsatisfactory operationand a major repair bi ll.

• Do not cut trees flush with theground, as this allows dirt to mix with

the lubricating oil, forming an abrasivewhich quickly will wear the Chain andGuide Bar. If you have a large standof timber to cut ftush with the ground,we recommend you fell the tr es a fewinches from the ground with the ChainSaw, and then use the inexpensive Cir-cular Saw to cut o·ff the small stumps.

GAUGING AND

SHARPENING

Proper setting of the Depth Gauges,small projections that control the depthof bite of the Saw, is essential to suc-cessful operation. The Gauges are [Jotset at the factory; these must be set inthe field. A "Gauge-it" tool is furnished

with ach Chain Saw; follow the accomparrying directions to set the DeptGauges properly.

Use the sharpening set, provided wiyour Saw at no charge, to sharpen tChain Saw.

LUBRICATION

The Chain Saw has a separate OilinSystem which is attached to the Tracto

by brackets and clips.Ordinary motor oil-new or used-

may be used in the Oiling System.operate, simply depress the thumb levon the can. Use oil liberally durinoperation.To disconnect, detach the rubber tub

Irnm the copper pipe. The tank acopper pipe may be lefl on the Tractoif desired.

CIRCULAR SAWAttach the 18-inch Circular Saw a tDrive Assembly as follows:

1. Remove the Collars and nut f~)the Rotor Shaft.

2 _ Place the %-inch and Jh-inch Clars onto the Shaft with the counterbored sides facing the end of the Sha

Put the Circular Saw on the Shalt, anthen the J , t , . -inch Collar, with the couter-bored side facing the Saw. Tightetile 11U securely. [ote: Cutting edgor the Saw teeth must face in the diretion of Shaft rotation. See "Attachingto Drive Assembly" under Chain Sainstructions to determine the directionof Sha t rotation,

OPERATING HINTS

Feed the Circular Saw from the sijust as you would feed the Chain Sawby exerting slight pressure on the 'I'ralor Handles. Do not force the Saw;

it "eat" into the tree gradually.• The Circular Saw is most effectiv

for clearing land of saplings, sproutsand other small growth. We do not reommend the Circular Saw for fellinlarge trees; the Chain Saw does this beter and faster .

• Drive the Tractor slowly, swingingthe Saw slightly from side to sideclear a wider path. Experience will dtate when iL is best to stop your forwardmotion and concentrate on a sproutsapling too large to "drive through."

• Be careful not to run the Saw inthe ground or against rocks.

OPTIONAL SAW GUARD

An optional Circular Saw Guard, whicattaches to. the Gear Housing by a splring, is available from your Gravelydealer. When ordering, give the modnumber of your Drive Assembly.

SHARPENING THE SAW

We do not recommend field sharpening.Have this done by someone specializingin circular saw sharpening, or by youGravely dealer.

STORAGE

When the Circular Saw is to be storefor several days or longer, we recommend you coat it heavily with GeneraPurpose Grease.

pose Grease in the swivel casting greasefitting, 2 in Figure 25 .

DEPTH OF CUT

ADJUSTMENT

Use the pin or clip, 3 in Figure 25, inthe Hex Shaft for initial cutting depthadjustment. The higher on the Shaft thePin is inserted, the lower the depth of

cut and vice versa. Ordinarily, the Pinis inserted in the topmos hole for plow-ing and in the bottom hole for trans-porting.A final cutting depth adjustment, if

required, is made by sliding the WheelBracket Clamp, I in Figure .26, up ordown in the slotted Wheel Bracket. Thelower the Clamp is et, the low r thedepth of cut.

PLOWING ANGLE

ADJUSTMENT

When plowing for the Ilrst time, set thePlow at the approximate angle to theground as shown in Figure 26. The nutwhich secures the Angle AdjustmentLever must be loosened to do this; besure it is tightened fi rm ly after theproper angle is set.

If there is excessi ve drag to the left(left, as you stand at the Handles) move

16

the Plow in the direc ion of the arrowin Figure 26. If there is excessive dragto the right, move the Plow opposite hedirection of the arrow.

A few trials may be required beforethe Plow is adjusted properly to soil

conditions.

WIDTH OF CUT

ADJUSTMENT

The width of cut is governed by the posi-

lion of the Wheel Bracket in relation

to the Depth Wheel in the Iurrow. The

closer he Whce l Bracket is to the Depth

Wheel in the furrow, the narrower the

cut, and vice versa.

D IR T S HIE LD

The optional (al. no extra cost) Dirt

Shield is attached to the top of the Gear

Housing by removing the bolts, 4 _ in

Figur 25, inserting them through the

Shield, and replacing in the Gear Hous-

ing. You can use the Dirt Shield to

direct the throw of the dirt by bending

it up or down.

ROTARYCULT IVATORThe Rotary Culti va tor is attached to theRotary Plow Drive Assembly as follows:

1. Leave the Plow Angle AdjustingAssembly (upper left in Figure 25) at-

tached.2. Remove the Hex Shaft (and Plow

Blades) from the Gear Housing.The Depth Wheels, Wheel Bracket,

and Column Assembly (which connectsthe Wheel Bracket to the Gear Housing)may be removed, as these serve no use-ful purpose unless you wish to operatethe Cultivator with the Tines cuttingagainst the motion of the Tractor (see"0pera ting Hints").Note: After the Column Assembly

has been removed, bolts must be insertedinto the Gear Housing to prevent oilleakage, We recommend short bolts forthis purpose; if the original bolts aretightened, the gears inside the GearHousing will be fouled. If, however, youuse the origin al bolts, place sufftcren t

washers on them to prevent gear fouling.3. Rotate the Gear Housing 180· so

the Oil Filler Plug is on the bottom. Re-move the four holts from the bottom ofthe Gear Housing and insert the studsfurnished (I[ you do not have a studdriver, two nuts may be locked togetheron the threads and used to seat thestuds, remove the nuts after seating thestuds) .

4. Fit the Hood as shown in Figure28. Insert the Cultivator Drive Shaftinto the Gear Housing.5. Use the elastic stop nuts to fasten

the Culti va l or Dri ve secu rely to the GearHousing.6. Rotate the Cultivator to the posi-

tion shown in Figure 29. In this posi-tion the Tines will cut in the same dlrec-

tion (clockwise) as the forward move-ment of the Tractor.

7. Install the Dust Sh ield and Fas-tener on top of the Hex Shaft.S. Use the Adjusting Bracket to lock

the Cultivator in place with the longaxis of the Cultivator parallel to theTractor Axles.Note: The Gravely Triple-Purpose

OPERATING HINTSThe Rotary Cultivator is designed foculti vating soil which has been brokenpreviously. It is not recommended fouse as a plow. Use the Gravely RotaryPlow to prepare a perfect seedbed in oneoperation and the Rotary Cultivator foperfect cultivation throughout the season.

• Cultivating depth is controlled bylight pressure on the Handles. When theTines are set to move clockwise-c-as theyusually are-depth is controlled generally by the design of the Cultivatoritself, about three inches ..

• To cultivate slightly deeper thanthis, raise up on the Handles; conversely,to cultivate shallower than three inches,place slight pressure on the Handles.

• Direction of Tine rotation also controis ihe depth of cultivation. As a general rule, to obtain greater depth, when

attaching the Cultivator to the GearHousing, rotate it L80· so the Tines revolve counter-clockwise, rather thanclockwise, when the Tractor moves forward. When used in this manner, werecommend use of the Rotary PlowDepth Wheel Assembly to keep the Cultivator from "digging in" and stalling theTractor.

• When cultivating crops such as corn,which usually require some dirt thrownaround the plants, remove the EndPlates. In other instances, such as cultivation of bushy crops, keep the EndPlates attached to the Hood.

LUBRICATION

Check the Drive Assembly oil levelevery eight hours of operation by re-moving the Oil Filler Plug, 1 in Figure34, and observing whether the gears dip

halfway in the oil.

Add oil, if necessary, through the OilFiller Hole. Use SAE 14.0.

Be sure the Tractor and Brush arelevel when checking or adding oil.

Use General Purpose Grease in thegrease fitting (or grease cup) on the

Drive Assembly (this is close to thepoint where the Drive Assembly is at-tached to the Tractor).

ADJUSTMENTS

To adjust the Chains, simply remove ahalf link when the Chain has been driv-ing long enough io "stretch." This us-ually occurs after several months of use.

To adjust Brush contact, put the Brushin contact wi h he ground by lifting up011 the Brush Can ac Lev r, 2 in Figure

In addition, the Cu Ii v a t or Too IHolderis used to hold the 36-inch ScraperBlade.

ATTACHING TO TRACTOR. TheTool Holder is attached to' the [rant of

the Tractor by four bolts, as are powerattachments. The Attachment ClutchLever (or Attachment Clutch Control)should be at the OUT position.ATTACHING TO. 0. L S TO. TOOL

HQL.DER. The individual cultivatingtool, ! in Figure 35, is attached to aShank, 2 in Figure 35, which in turnis attached to the Tool Holder by aShank Holder, 3 in Figure 35.The Tool Holder comes from the fac-

tory with five Shank Holders. Thesemay be moved to different positions onthe Tool Holder, if desired, although thisis seldom necessary. Additional ShankHolders may be purchased from yourGravely dealer.Cultivating tools are divided into two

classes - those requiring the one-hole

Shank and those requiring the two-holeShank. W~th the exception of the Fur-rowers, Hillers, Shovel Steel, and 'I'urn-

ing Shovel, cultivating tools require theone-hole Shank.To attach a tool to its Shank, simply

bolt it in place with the nuts and boLtsprovided.To attach the Shank to the Tool

Holder, loosen the hexagon-head capscrew in the side of the Shank Holder,slip the Shank into the Shank Holderfrom the bottom, and leek the Shank inplace at the desired position by tighten-ing the cap screw.

CHANGING TOOL. After theShanks have been attached to the ToolHolder, changing cultivating tools reoquires only the unboleing o:f the old tool

hom its Shank and bolting the new toolon. However, if the new tool requires atwo-hole Shank in place of a one-holeShank, the Shank also must be changed.PARALLEL BARS. The Parallel Bars,

.. in Figure 35, can be adjusted in sev-eral ways, depending on the task Usu-ally it is necessary to detach the Barsfrom the Depth Wheels to make thesedifferent set-ups.

ADJ TMENTS. The Depth Wheelsare used to set the depth the culti vatingtools penetrate the ground Facing theDepth ViI"heels, turn the Handwheelsclockwise for deeper cultivation andcounter-clockwise for shallower cultiva-tion.Usually the Depth Wheelsprovide all

LUBRICATION


OPERATING HINTS

Individual problems and preferencesusually wiI! govern the cultivating depthand how close to the plants you culti-vate. However, these suggestions gener-ally will be helpful:

" Cultivating depth within the pathof the Tool Holder may be adjusted by

the individual Shanks. For example,Shanks may be set for deep cultivationin the center, while barely stirring thedirt next to the plants. This cuts downall. hand-hoeing, and does not damagethe plants when done with care.

I Rows should be planted enoughapart to accommodate the Tradal' andTool Holder. Normal distance betweenrows is 32 to 36 inches. Rows shouldbe planted farther apart for plantswhich spread widely, unless you intendto shield the Tool Holder so plants willnot be damaged.

" The Tool Helder and cultivatingtools are very useful Ior stirring up deeplitter in brooder houses.

• When cultivating very hard or stony

ground, place a 50·pound sandbag on theTool Holder La keep it from bouncing.Use of the sandbag makes no appre-ciable difference in \112 handling of theTractor.

Note: Users sometimes ask us whythe Tool Holder is not made heavyenough so use of the 50-pound sandbagis not necessary. To make the ToolHolder 50 pounds hea vier would requirea price increase of S 18 to $22. We be-lieve users' interests are served betterby recommending this simple and inex-pensi ve way to obtain lhe needed weigh t,when necessary, rather than forcingusers to pay more money unnecessarilyfor the attachment.See Page 22 for Rear Culti vator Tool

as 18 inches. Key to its efficiency iunique design-instead of pushingsnow, the Snowplow rolls it out .ofway.The Snowplow has many uses in

dition to removing snow .. These arecussed under "Additlonal Uses."

Snowplow



DIU TMENT . The current Snow-pi w has a Swivel Casting (the SwivelCasting is the part which is attached tothe front of the Tractor) which has threeholes in it. The Snowplow can be ad-justed so there is swivel action, allowingthe Blade to follow closer the groundcontour, or it can be set so the Blade isheld rigidly.The older Snowplow does not have

this swivel action feature; its Swivel

Casting has only one hole.Both models can be adjusted to roll

the snow straight ahead or to the len orright.To set the n 'W Snowplow to roll

straight ahead with swivel action, lineup the cent r hole in the Swivel Bracketwith the center hole in the Swivel Cast-ing and insert the T·shaped AdjustingPin. To hold the Blade rigidly in thestraight-ahead position, insert the Pinin the holes on either side of the centerholes.To roll snow to the left wi th swivel

action, line up the left (left, as youstand at the Handles) hole in the SwivelBracket with the center hole in heSwivel Casting and insert he Pin. Tohold the Blade rigidly in the left position,

insert the Pin in the holes immediatelyto the righ t,To roll snow to the right with swivel

action, line up the right (right, as youstand at the Handles) hole in the SwivelBracket with lhe center hole in theSwivel Casting and insert the Pin. Tohold the Blade rigidly in the right posi-lion, insert the Pin in the holes imme-diately to the left.

On the older Snowplow, simply movethe Blade to the desired position, lineup the boles in the Swivel Bracket withthe hole in he Swivel Casting, and in-sert the Pin.

WEARING TRIP. The Wearing Stripon the bottom of the Blade eventuallywill have to be replaced. To replace,simply remove the screws, take off theold Strip, put the new Strip on, andlighten the screws firmly.

KID . Skids, available from yourGra vely dealer, are useful when work-ing on concrete dri ves where one side ishigher than the other (thus forming anedge which would catch the Blade) andon gravel or bluestone drives to keep theBlade high enough to remove the snowwithout removing the gravel or stone.To attach U1e Skids, remove the end

screws from tile Wearing Strip and in-sert the long bolts provided with theSkids. Slip the Sltids onto the bolls fromthe rear of the Blade, with the long sidesdown and parallel to the ground. Fastenthe nuts securely on the bolls.

RECOMM.ENDED ACCE ORIE.

Gravely Tire Chains (see Page 6) arehelpful when removing snow from ice-coated pavements. When using theSnowplow for light bu.lldoz ing, the DualWheels described on Page 5 in manycases may be desirable.

L BRI ATIO . No lubrication is re-quired.

ADDITIONAL SES. The Snowplowis used by many landscapers in combina-tion with the Rotary Plow and RotaryCultivator to prepare lawns for seeding.After plowing, the Snowplow can beused to terrace and grade. Many usersgo over the area to be seeded with theTractor in reverse, so that the Snow-plow follows the Tractor. This makes asmooth, even seedbed properly prepared

REAR H ITCH IN STRU CT IO NSNon-power attachments used on the rearof the Tractor are classified according

to the manner each is secured to theRear Hitch:• Attachments bolted to the Rear

Hitch Frame: Rear Cultivator ToolHolder and Steering Rider;

• Attachments using the Split-SocketConnection: Disc Harrow, Turn Plow,

and Rider; and, . .• Attachments using the Roller-Rest

Connection: Hay Rake, Lawn Roller,Transportation Cart, and 5-foot Seeder·

Spreader.When using an attachment on the rear,

if you are not using an attachment onthe front of the Tractor at the same time,the front of the Tractor must be pro-tected by an Attachment Boss Cover andgasket, or the Cultivator Tool Holder(without cultivating tools).The

AttachmentBoss Cover and gas-

ket are secured to the front of the Trac-tor by four bolts, in the same manner aspower attachments are secured.

ATTACH ING REAR HITCH

The Gravely Rear Hitch, shown in Fig-ure 41, is attached as [allows:

1. A llach the Bra ces, 1 in Figure 41,to the Rear Hitch Frame loosely, usingthe bolts, nuts, and lockwashers pro-vided. Be sure the short twist on each

Brace is down.2 _ Remove the second bolt from the

bottom on both Tractor Axle Housings.

Figure 41

Slip the Frame into place, with thecross-member at the extreme end of theFrame on top. Use the two long boltsprovided to secure firmly the Frame tothe Tractor Axle Housings.

3.. Remove the nuts from the FanHousing, slip the Braces all, and replacethe nuts. Note: On Tractors with SerialNumbers less than 80,000, the length ofthe stud on the Brackets which hold theFan Housing to the Tractor may be in-adequate if both the Rear Hitch Bracesand Governor Bracket are mounted. Inthis case, see your Gravely dealer forBrackets of the proper length.

4. Place the large nut on the BallStud,2 in Figure 41, and run it up to theend of the threads. Screw the Ball Studinto the hole in the cross-member on theend of the Frame. Place the second nuton the Ball Stud and lock both nutstightly against the cross-member. Be

sure the Ball Stud hangs under the cross-member and not on top of it.

5. Tighten securely -the nuts whichhold the Braces to the Rear HitchFrame.

LE VE LIN G THE TR AC TO R

Sometimes it is necessary to "level" theTractor when using the Rear Hitch tokeep the Handles from hitting yourknees when turning. To do this, loosenthe lock nuts on the Ball Stud and turnthe B'a11 Stud (with a %-inch Alienwrench) clockwise to raise the Handles(or counter- clockwise to lower the Han-dles).Note: After this adjustment, be sure

lhe lock nuts on the Ball Stud are tighJt-ened securely.If there still is interference, loosen

the rearmost bolts which hold the Han-dies to the Tractor, move the Handlesup (or down) wi thin the slots un til theproper height is reached, and tightenthe bolts securely.
