WARNING: When driving on ice it isrecommended to keep the roof hatch open.

6 Passengers --- No passenger may ride on the tractorunless it is provided with a special seat. Any passengermust not ride on the platform placed in the tractor. Otherpersonal transport, for example, on front---mountedloaders, is not permissible.

7 Caution --- Hold on to the steering wheel or safetyhandles in the cab if the tractor tips over. Never try to jumpout.

8 Maintenance --- The driver is responsible for followingthe maintenance instructions in this Manual and the safetyregulations applicable to the tractor. No maintenancework is to be carried out on the tractor or implementunless the engine is stopped and the implement lowered.

9 Lending --- Never lend the tractor to a person who is notused to driving it. You may be held responsible for anyresulting accidents.

---8---B. Safety precautions

10 Lights --- Always make sure that the lights andreflectors are clean and in working order. Do not forgetthat the headlights must be correctly adjusted.

N B1

11 Carbon monoxide --- Never start the engine, or run itindoors while the doors are closed as this may lead tocarbon monoxide poisoning.

12 Downhill --- Never drive downhill with the gear lever inneutral or the clutch pedal pressed down. Check thebrakes often. Always change down to a lower gear beforedriving down a steep incline. When driving downhill do notbrake continuously --- Danger of overheating thebrakes! Do not let the engine over run to avoid damage tothe engine.

13 Running speed --- Adjust the speed to suit the drivingsurface, visibility and load. Avoid any sudden increase orreduction (braking) in the running speed as well as tightturns at high speed. If care is not taken the tractor may tipover or the load may be displaced.IMPORTANT: The maximum speed of the tractor mustnot be altered.Maximum operating forward speed is 40 Km/h (traffictractors 50 Km/h), for safety the maximum operatingspeed in reverse is 20 Km/h.

14 Power take---off driven attachments --- When runningwith power take---off driven attachments or machines it isvery important that the prescribed safety devices are usedand that they are in good condition. Serious accidentshave occurred due to failure to use the prescribedsafety devices. Follow the directions given by theimplement or machine manufacturer.

15 Check links --- When transporting implements usingthe three---point linkage, the check links must be lockedwith pins.

16 Emergency exits --- The cab is provided with fouremergency exits. These are the doors, the rear windowand the roof hatch (extra equipment).

17 Stairs --- Keep the stairs clean. Build up of dirt can cau-se slippery conditions and can cause injury.

18 Trailer load --- On tractors with trailers the load mustbe properly secured. The load must not obstruct thedriver’s vision or cover lights and reflectors. Loads whichproject more than 1 m (39 in) behind the vehicle train

must be suitably marked. During day-time this should bedone with a flag and during darkness with a red light andreflector arrangement.

19 Trailer --- A trailer should only be coupled to thedrawbar. A loaded drawbar must always be lowered withthe hydraulic lift. Check that trailer brakes are operatingproperly and observe any special instructions issued bythe trailer manufacturer.

WARNING: When the tractor is towing atrailer the brake pedals must be lockedtogether. The brakes are not to be usedindividually for steering.

WARNING: When using a trailer make surethat the hitch latch is locked.

WARNING: When using the trailer alwaysuse the brakes, if the law requires.Thetrailer brakes are recommended to use in 50km/h models also in those countries, whereit is not required by the law.

20 Front---end loader --- When working with a frontloader, be sure that no one is in the working area. There isa danger that the tractor may tip over when the loader islifted. The driver should put the front---end loader in thedown position before leaving the tractor. Any specialinstructions issued by the loader manufacturer shouldalso be observed.

21 Running --- Before driving always check that the tractoris in a safe condition for driving on the road. Rear viewmirrors should be adjusted to give the correct viewingangle before setting off. When towing an implementwhose centre of gravity is located at a significant distancebehind the tractor, the driver should remember that theremay be considerable sway during cornering.

22 Differential lock --- The differential lock must only beused when running on loose or slippery ground.

NB2

23 Ballast weights --- When driving on the road at least20 % of the gross weight of the tractor must be on thefront axle. When lifting an implement the weight on thefront end of the tractor is reduced, and the steering abilityof the tractor is impaired or sometimes lost. Thereforesufficient ballast weights should be carried. Ballastweights should be mounted only at the points intended forthis purpose.

24 Attaching implements --- Care must be taken whenimplements are being attached. There is a risk of an

---9--- B. Safety precautions

accident if the tractor or implement should move. It is onlysafe to enter the space between the tractor and theimplement if the parking brake is applied or the wheelsblocked in order to prevent the tractor from moving.

25 Damage --- The driver is responsible for seeing to therepair of any damage or wear which might endanger thesafety of the tractor.

WARNING: If damage occurs to the cab, allparts affected should be replaced with newones. No repair work (welding, drilling,cutting, or grinding) should be attempted.

A6084---10

26 Triangle for slow vehicle (SMV---Slow MovingVehicle) --- When driving on public roads always use theSMV emblem on the rear end of the tractor. Also use therotating light where required by law.

A6084---10,1

27 Mobile phones --- Mobile phones may cause failure forthe electric linkage function. A mobile phone can not bekept inside the cab, especially above the right side panel.When using a mobile phone in the tractor it is

recommended that it is connected to the outside antenna.

28 Hydraulic/fuel pressure --- Oil/fuel under highpressure easily penetrates through clothing and skin andcan cause serious injury. Never attempt to locate a leak inthe hydraulic system or attempt to close a leak using anypart of your body.

29 Implements maintenance --- Implements connected tothe linkage or the auxiliary hydraulic system must belowered to the ground during maintenance.

30 Motor noise --- When you are operating the engine orworking near it, use hearing protectors to avoid noiseinjuries.

31 Naked flames and smoking --- Naked flames,smoking and sparks are prohibited near the fuel systemand batteries. (Specially, when charging batteries,explosive gases present).

32 Cleaning --- Keep the tractor clean (cleaninginstructions see on page 114). Avoid the risk of fire bythroughly cleaning before use!

33 By a fire --- At temperatures in excess of 300˚ C, e.g. ifthe engine is on fire, the viton seals of the engine (e.g theundermost 0---ring of the oil pressure regulating value)produce very highly corrosive hydrofluoric acid. Do nottouch with your bare hands, viton seals which have beensubjected to abnormally high temperatures. Always useneoprene rubber or heavy duty gloves and safety glasseswhen decontaminating. Wash seals and the contaminatedarea with 10 % calcium hydroxide or other alkali solution.Put all the removed material in sealed plastic bags anddeliver them to the point stated by the Authoritiesconcerned.

WARNING: Never destroy viton---seals byburning!

34 Engine stop and restart --- If the engine has stalledeg. due too heavy loading, turn the ignition switch to theSTOP position. Restart the engine according to the start-ing instructions. Keep an eye on the indicator lights on theinstrument panel.

35 Quick couplings for lower links --- Clean, if necessarythe quick couplings and ball joints for the lower links befo-re attaching the implement. DANGER OF THE IMPLE-MENT RELEASING!

C 2. ServiceIn order to function satisfactorily the tractor must beproperly maintained. The necessary daily lubrication androutine checks, can, of course, be carried out by thedriver.Where adjustments and repairs are necessary whichrequire the attention of a qualified mechanic and the useof special tools, it is advisable to rely on a workshop. Inthis case we advise you to consult your local dealer as to

how your tractor should be looked after as he is in aposition to give you the best possible service. Throughservice bulletins and special training courses he is keptconstantly informed of the factory’s recommendationsregarding care of the tractor.

C 2.1. Cost---free service

Before leaving the factory the tractor was thoroughlytested and adjusted to ensure it is in first-class conditionwhen delivered to you. However, it is important that thetractor is given further checks during the first period ofoperation.

Bolts must be checked for tightness, various settingsinspected and other minor adjustments made. Your dealertherefore provides a cost---free service inspection(excluding oil and filter costs) after 100 hours running.

Two power ranges--- The models N101cCR, N101hCR---N141h have also alarger transport boost power area, when the main gearis H2 or higher (on the 50 km/h models H1 or higher).--- On the model N111ehCR it is possible to choose eitherlow engine range (maximum 1800 r/min) or standardengine range (maximum 2200 r/min) with the Ecoswitch. When using the low engine range, the fuel con-sumption, emissions and noise are all reduced.The principle of the turbocharged engine is that exhaustgases from the engine cylinders drive the turbo unit whichforces air into the cylinders. This means that higher poweroutput can be obtained with economical fuelconsumption. On intercooler models cooled inlet air is fedinto the cylinders.

The engine induction air passes through the air filter and asafety filter inside the air filter. The air intake system hasan effective ejector system, most of the impurities areremoved before they reach the filter by the exhaust fumeflow. The safety filter prevents the engine being damagedif the main filter fails.

These engines have lower fuel consumption and cleanerexhaust gases.

C 3.1. Electronic enginemanagement (EEM)

On the models N111ehCR, N121h and N141h the electro-nic engine management includes a controller installed onthe engine (EC).

The electronic engine management improves thetechnical features of the engine such as fuel efficiency,power, torque and cold starting. It also reduces emissionsand noise. On the models with lower output, thesefeatures are achieved with the new feed pump.

C 3.2.Common Rail

In the Common Rail system the injection pump has beenreplaced with the high---pressure pump, which pumps theamount of fuel to over 1000 bar pressure, to the highpressure accumulator (rail), common for all cylinders. Thehigh---pressure fuel injects to the cylinders through theelectric controlled injectors. The Common Rail systemmakes it possible to develop quiet---running, economicengines featuring, reduced emissions and noise,especially by lower rotating speeds.

C 4. Power transmission

C 4.1. Clutch, Nc models

N C10

The clutch is disengaged hydraulically and is coupled tothe flywheel. It has a single dry disc with a diaphragmspring. The clutch disc diameter is 330 mm. The discmaterial is organic. Clutch disc vibration damping hasbeen improved. This causes lower noise levels andsetting---off is now smoother. The clutch operates by fluidand is self adjusting. As extra equipment it is available tohave the push buttons for HiShift for making driving easierso there is no need to use the foot clutch pedal.Traditional use of clutch pedal is however always possible.


C 4.2. HiTech power shuttle, Nh models

68c 23

In tractors with the HiTech power shuttle unit thetraditional forward/reverse gear lever is replaced with ashuttle lever beside the steering wheel.By moving the shuttle lever forwards or backwards (thecentre position is neutral) you get a gentle and lightshuttle operation without using the clutch pedal. Use ofthe clutch pedal for shuttle operation is still possible.

The power shuttle is placed between the gearbox and thePowershift. It has planetary---type gear drives which areoperated by two wet multi ---disc clutches, one for forwarddriving and one for reverse driving. Multi disc clutchesoperate at the same time as the driving clutch due to thisthe tractor not having a traditional dry clutch disc.

The function of the HiTech system is controlled by theelectronic control unit of the gearbox. This means that theelectronics smoothly adjust the disengaging andengaging pressures of the hydraulic multi ---discsaccording to program. This provides smooth forward andpower shuttle driving.

In addition the system has the HiShift --- operation, withswitches placed in the speed gear--- and range lever,which controls the operation of the multi ---discs whenchanging gear. So it is possible to change gear withoutusing the clutch.However, traditional use of clutch pedal is still possible.

A6181---16,1

The models N101h HiTrol---N121h HiTrol (not N111ehCR)are also fitted with a hydraulic coupling for smoothertransmission. The hydraulic coupling allows shock freetraction; it is of particular benefit when ground conditionsare slippery or when the tractor is heavily loaded.Additionally, the speed differences between gears areevened out.


The hydraulic coupling also protects the clutch disc andother transmission components from uneven andexcessive load peaks.

C 4.3. Gearbox

The speed gearbox has four synchronized gears whichare controlled with a speed gear lever. In addition, thegearbox has three range gears; LL=creeper range(alternative equipment, standard in 50 km/h models andN111ehCR), M=Medium range and H= High range. Mand H ranges are synchronized. All this range of gears arecontrolled with one lever.There is an EcoSpeed---function available on the modelsN111ehCR, N121h and N141h(as alternative equipment).The EcoSpeed---function is based on the 50 km/htransmission and the highest ratio with the electric speedlimiter (40 km/h). When driving at road speeds the fuelconsumption is lower and the noise will be reduced.

Nc models

Between the Powershift and gearbox there is aforward---reverse shuttle and this is synchronized. Theforward/reverse shuttle is controlled with a separate lever.For this reason forward/reverse changing can be madequickly and very easily e.g when loading work is carriedout.

C 4.4. Powershift

In addition in front of the gearbox is a 3---step quick---shiftgear, the Powershift.

The main gearbox has 8 speeds forward/reverse andwith LL (alternative equipment) 12 speeds forward/re-verse. The 3---step Powershift gear on the tractors give24 gears forward/reverse and with LL (alternativeequipment) 36 gears forward/reverse.Shafts and gearwheels in the gearbox are pressure lubri-cated.

Nc models

The Powershift is controlled with push buttons placed onthe speed gear lever knob.

Nh models

Control of the Powershift function is also controlled by theelectronic control unit, at which time the gearing isselected according to the driving conditions.Manual control of the Powershift --- gears is done with thepush buttons on the gear lever. The driver can choosefrom the system, preprogrammed automatic functions ofPowershift for different driving conditions and powershuttle.

The digital display panel in the tractor keeps the driverinformed at all times by displaying the status of differentoperations, e.g.:--- driving direction--- which of the Powershift --- gears is engaged--- chosen automatic operations---outdoor temperature--- shows when the PTO is engaged---indicates any possible fault with a fault codeAnd in addition it suggests when to change to a lower orhigher gear.

C 4.5. Rear axle

The rear axle is fitted directly to the gearbox. Thedifferential lock in the rear axle is electro---hydraulicallycontrolled. When it is engaged, pressurized oil is pumpedto the multi ---disc differential clutch, and this causes thedifferential to lock. When the brake pedal is pressed thedifferential lock is automatically disengaged. An indicatorlamp on the instrument panel lights when the differentiallock is engaged.Final drives are of the planetary gear type. From theplanetary gears power is transmitted to the rear wheels.

C 4.6. Powered front axle

M C7

The powered front axle is driven from the gearbox bevelpinion shaft front end.

Front wheel drive can be engaged and disengagedelectro---hydraulically. When 4WD is engaged the springsforce the discs together and four---wheel drive engages.Consequently the 4WD is always engaged when theengine is stopped (multi ---disc clutch not pressurized).In addition when braking, the front---wheel drive alwaysengages in order to provide the braking function for thefront wheels.

The front axle is also equipped with an automaticdifferential brake. Simultaneously electro hydraulicallycontrolled front axle differential lock is available asalternative equipment.The suspensioned front axle isavailable as extra equipment on all models.


C 4.7. Power take---off

A6181---19

The PTO rotating speed is selected with a lever, which canselect either 540 r/min or 1000 r/min nominal rotatingspeed. Engagement and disengagement is electro---hydraulically through a different button. It is also possibleas alternative equipment to have a 540E (750) r/min PTO(not N111ehCR).

Nh models

The control unit of the gearbox also controls the functionof the power take---off. This makes the power take---offengagement smooth without loading the implement. Thedisplay shows a symbol if the power take---off shaft isrotating.

All models

The power take---off shaft is easy to change. As standardthe tractor is provided with a 6---spline shaft and as extraequipment shafts with 21---, 20---, 6--- or 8 splines forgreater torque can be fitted on the tractor.As alternative equipment a ground speed PTO is alsoavailable.

The front power take---off is available as extra equipment(with front linkage). The front PTO shaft nominal rotatingspeed is 1000 r/min and the shaft is 6---spline.


C 5. Brakes

N C8

The oil bath multi ---disc brakes are located on the rearaxle between the differential and final drives. The brakesoperate hydraulically from the brake pedals. When bothbrake pedals are depressed the front wheel drive is en-gaged automatically in order to provide braking functionat the front wheels. The pedals can be connected togetherand used as running brakes or separated and used indi-vidually as steering brakes. The brakes can be adjustedby means of adjusting nuts which are fitted on the rearaxle.

Nh models

The parking brake is electro---hydraulic and is controlledwith a shuttle lever. When engaging the parking brake, thepressure exhausts from the cylinder operate the parkingbrake and a strong spring engages the tractor brakes. Atthe same time the control unit disengages the trans-mission. With this system the tractor brakes are always onwhen the engine is not running.

Nc models

The parking brake is mechanically operated and it acts onthe foot brakes.

All models

A trailer brake valve and the air pressure brakes are avail-able as extra equipment.


C 6. Steering system

M C8

The tractor has a hydrostatic steering system so thatsteering movement is transmitted from the steering wheelby oil under pressure to the front axle. This makessteering particularly easy.

If the oil pressure in the steering system should fail for anyreason, steering is still possible by manual power, and thesteering valve will act as a pump.The tractor hydraulic system has a priority valve whichensures that there is always sufficient oil for the steeringsystem.


C 7. Hydraulic system

N C26

UUSI KUVA

The tractors hydraulic system has both a low pressurecircuit and a high pressure circuit. Both circuits have theirown pump. The capacity of the low pressure circuitpump is 30 l/min at 2200 r/min. The high pressure pumpcapacity is 73 l/min at free flow pressure which enableseffective use of the auxiliary hydraulics.

The high pressure circuit controls:--- steering system (prioritized)--- working hydraulics--- auxiliary hydraulics--- trailer brake valve (extra equipment)The low pressure circuit controls:--- quick---shift gear--- powered front axle--- PTO--- differential lock--- gearbox lubricationTractors have, as standard, an electro---hydraulicAutocontrol B (=ACB) linkage. The linkage is controlledthrough the electrical potentiometers and switches.

Pre---programmed functions:--- draft control/position control combining ratio plussensitivity on the regulator, the sensitivity adjustment isautomatic.--- lowering speed (independent of load)--- transport height--- drive balance control systemMax. lifting capacity of the hydraulic lift is as follows:--- Ø 90 mm lift cylinder 5700 kg--- Ø 100 mm lift cylinder 7000 kg, extra mounting holes7900 kg

The front linkage is available as extra equipment. Liftingcapacity of the front linkage is 3600 kg.


C 7.1. Valves for auxiliary hydraulics

N C27

The tractor has two valves for auxiliary hydraulics asstandard and these are controlled by separate levers.Both of these valves are adjustable for eithersingle---acting or double---acting functions. One of thesevalves can be locked mechanically in position while theother valve has a ”floating position”.Standard quick---action couplings or Push---Pull typecouplings are available.

Two additional valves and an oil flow distribution valve canbe mounted as extra equipment. In addition, a trailerbrake valve can be mounted as extra equipment.
