933C Hystat Track-Type LoadersOffering rugged construction and outstanding reliability to allow you to maximize productivity.
Power TrainA powerful six-cylinder Cat® 3046engine and the new hydrostatic powertrain system provide the power youexpect from Cat 933C Hystat track-typeloaders. You also get the productivityyou need to stay competitive.
Hystat system - a dual-path, closed-loophydrostatic power train provides fullpowerturn capability, stepless speedrange, dynamic braking and smoothmodulation for steering and directionalshifts.
pg. 4-6
Hystat ControlYou’ll be amazed with how much dirtyou can move with one hand using a933C loader. A single joystick allowsyou to control speed, direction andsteering, effortlessly. . pg. 7
Outmaneuver every job you tackle.A single lever joystick control is all that is needed to controlspeed, direction and steering on Cat® 933C Hystat Track-type Loaders. Full powerturn capability is made possible bymaintaining power to both tracks at any ground speed orturning radius. You’ll find operating a loader of this size hasnever been easier or as much fun.

Operator StationSuperior comfort awaits you day-in andday-out whether you opt for an opencanopy or a loader equipped with a cab.Visibility is excellent, controls areergonomically designed and wellpositioned, and arm rests are fullyadjustable for optimum comfort andproductivity. The 933C is equipped witha new dash panel and vandalismprotection guard.pg. 8-9
Bucket & Lift ArmsAvailable general purpose or multi-purpose buckets increase machineversatility. Four-plate loader towers andlarge, solid-plate lift arms providemaximum strength and resistance toshock loads and loading stresses. Liftarms are reinforced with a crossmemberto reduce torsional bending duringloading. pg. 10

UndercarriageWith soil conditions changing with eachjob you tackle, you need anundercarriage built rugged for longwear life and low owning and operatingcosts. That’s why all 933C loaders arebuilt with sealed and lubricated track.Sealed-in lubricant permanently coatsthe track pin, minimizing metal-to-metal contact and virtually eliminatinginternal pin and bushing wear.Undercarriages have thicker recoilguarding for added impact resistance.New bolt-on, rear track guidingguards, standard on all models, furtherenhance rear guiding and provide extraprotection against abrasive wear.pg. 11
ServiceabilityNot only does the updated engineenclosure add to the impressive style ofthe 933C track loader, it also provideseasier access to grouped service points.Scheduled Oil Sampling (S•O•S) valvesare located on the engine oil filter andhydraulic filter housings for easy oilcollection by your Cat dealer. Increasedfuel capacity extends time dedicated tothe job. pg. 12✔
✔HydraulicsPowerful Caterpillar hydraulics provideexceptional strength for impressivebreakout force and lift capacity. Two7-micron filters keep dirt out toprovide long component life. Matchedhydraulic valves and loader linkagesprovide precise and lasting bucketcontrol for superior load handling.Hydraulic pump capacity has beenincreased by 17 percent to improveproductivity. pg. 4

The Hystat system provides maximumperformance everyday, no matter whatyour job application. The Hystatsystem features:
■ Full powerturn capability at anyground speed or turning radius;
■ Stepless speed range from 0 mph tomaximum;
■ Smooth modulation for steering anddirectional shifts;
■ Dynamic hydrostatic brakingprovides full control of machinespeed without using brakes;
■ Superior maneuverability whenworking in tight areas;
■ Excellent controllability, especiallywhile operating in close quarters; and
■ Load sensing, which automaticallyadjusts speed and torque to matchchanging load conditions.
1 Hystat pumps. Two high pressure,variable displacement piston pumpsare attached directly to the engineflywheel housing. No U-joints orsplitter box to service.
2 Track motors. Two high pressure, 2-speed piston motors are mountedinboard of the main frame at the finaldrives.
3 Cat’s XT hoses are well respected fortheir strength and durability and areused to connect the pumps to themotors. O-ring face seals are usedthroughout the entire Hystat systemand provide positive sealing forreliable, leak-free connections.
4 Two identical, vertically mounted,spin-on hydraulic filters are easilyaccessible and provide filtration forboth the Hystat power train andimplement systems.
5 Service brakes. Hydrostatic(dynamic) braking through machinedrive system using joystick control orcenter pedal.
Hystat Power Train SystemQuick response and acceleration plus better maneuverability decrease cycle times and increase produ
6 Double reduction planetary finaldrives provide high torquemultiplication between the hystatmotors and the drive sprockets.Drives are mounted independently ofthe track frames to isolate them fromground-induced shock loads.
7 Wet, multi-disc parking brakeslocated between each hydraulic trackmotor and final drive are springapplied and hydraulically released.Automatically applied when theengine stops, or operator appliedwhen the center pedal is fullydepressed.
8 Neutral-start parking brake leverdisengages transmission and engagesthe parking brakes to preventunintended machine movement.
9 Hydraulic oil cooler is an air-to-oiltype and provides cooling for thepower train and implement oil.
The Hystat system is a high pressure, dual path, closed loop hydrostatic power trainsystem. Each track is driven by a separate hydraulic circuit consisting of onevariable-displacement piston-pump, connected by Cat XT-6 hose and coupling to apiston motor.

The joystick control is simple and easyto understand. With it, you will controlthe direction, speed, and steering ofyour 933C Hystat track loader. Thejoystick is ergonomically designed tofit comfortably in the palm of yourhand. Control effort is minimal, somuch so that you might find yourselfusing your fingertips.
Direction/speed
■ Forward movement. As you move thejoystick forward, the machine movesforward, traveling faster as thejoystick is moved further forwardfrom the center position.
■ Reverse movement. When you movethe joystick back, the machine willmove in reverse, again travelingfaster the further the joystick ismoved back from the center position.
■ Stopping. The easiest way to stop themachine is to return the joystick tothe center position. The joystick isspring-loaded and will return toneutral by itself. You may also stopthe loader by pressing the centerbrake pedal all the way down withyour foot.
■ Turtle/rabbit switch. In turtle mode,the drive motors are fixed in themaximum torque position (workingmode). Switching to rabbit modechanges the drive motors to a higherspeed setting (roading mode). Toactivate the turtle/rabbit mode,simply use the toggle switch locatedon top of the joystick.
Steering
■ Right/left movement. With themachine moving in forward orreverse, moving the joystick to theright results in the machine turning tothe right; moving the joystick to theleft causes the machine to move tothe left. The more the joystick ismoved to the left or right, the tighterthe turn.
Hystat ControlSteering, machine direction and speed are combined into one control for enhanced operatorcontrollability, comfort and increased productivity.
