Matched Caterpillar components deliver smooth, responsive performance and reliability.
Cat 3306 EngineThe Cat 3306 continues its tradition of powerful, efficient performance and unmatched reliability and durability. The six-cylinder engine is naturally aspirated with a high displacement-to-power ratio.
PerformanceHigh torque output and high torque rise make the 3116 engine very responsive.
Fuel EfficiencyHigh fuel injection pressures ensure proper mixing of fuel and air.
Extended Engine LifeThe large bore-stroke design and conservative power rating help minimize internal stresses and increase component life.
Electronic Overspeed ProtectionElectronic overspeed protection helps prevent engine and transmission damage from premature downshifting and grade-induced overspeeding.
Power Shift TransmissionCaterpillar designs and builds transmissions specifically for Cat motor graders.
Direct DriveDirect drive delivers superior fuel efficiency and better "feel" of blade loads, material hardness and ground speed.
Gear SelectionsEight forward speeds and six reverse speeds give the operator a wide operating range.
Electronic Transmissions ControlElectronic transmissions control produces easy, smooth shifts, which enable the operator to maintain uniform surfaces if shifting is required.
Inching CapabilityLow pedal effort and excellent modulation provide precise control of machine movements when using the inching pedal.
Dual Air SystemThe dual air system supplies braking capacity to each side of the machine.
Oil Disk BrakesCaterpillar designs and builds multi-disc brakes that are completely sealed and adjustment-free.
Engine Power ManagementEngine power management delivers full-rated net power.
Balanced hydraulics deliver consistent, precise and responsive control.
Power On DemandNormally, the variable displacement pump idles at near-zero output.
Implement Control ValvesImplement control valves are designed and built by Caterpillar specifically for motor graders.
Low Operator EffortImplement controls are designed to reduce operator fatigue.
Balanced FlowWhen the operator uses several controls at one time, flow is proportioned to ensure all implements can operate simultaneously. If hydraulic demand exceeds pump capacity, cylinder velocities will be reduced by the same ratio.
Independent Oil SupplyLarge independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and extended component life.
Drawbar, Circle & Moldboard
Every component is designed for maximum productivity and durability. The blade linkage design maximizes moldboard positioning.
Blade PositioningThe blade linkage design enhances moldboard positioning.
Blade AngleA long wheel base allows the operator to obtain an aggressive moldboard angle.
Rugged ConstructionThe Y-frame drawbar is constructed of two solid beams.
Replaceable Wear ItemsTough, durable nylon composite wear inserts are located between the drawbar and circle, and between the support shoes and circle.
Circle Drive Slip ClutchThe circle drive slip clutch protects the drawbar, circle and moldboard from shock when the end of the blade encounters hidden objects.
Caterpillar sets the standard for comfort, convenience and visibility.
VisibilityExceptional visibility helps improve operator confidence and productivity in all grader applications.
Quiet CabWith the doors closed, interior sound level stays low. The quiet environment keeps the operator alert and focused.
Reduced Strain and FatigueLow efforts on all pedals, hydraulic controls and the transmission shifter reduce operator strain and fatigue.
Roomy InteriorExtra leg and foot room create a spacious, open cab.
Contour Series Suspension SeatThe optional contour series suspension seat features fold-up armrests and a retractable seat belt.
ComfortThe optional heater arrangement creates a comfortable work environment for the operator.
Electronic Monitoring SystemThe electronic monitoring system checks important machine systems and provides the operator with three levels of warning.
Features of ComfortComfort and convenience are designed into every feature.
Conveniently placed service points make routine maintenance quick and easy.
MaintenanceEasy access to service areas speeds up maintenance and ensures that routine service is performed on time.
Power Train ComponentsPower train components feature a modular design so you can remove the engine, transmission or final drives independently for quick servicing.
Diagnostic CapabilityDiagnostic capability offers fast servicing of the transmission.
XT HoseCaterpillar designs and manufactures its own heavy-duty XT hose and installs it in all high-pressure circuits. It's resistance to abrasion, coupled with its exceptional strength and flexibility, help minimize maintenance and extend life.
O-Ring Face SealsO-ring face seals create a reliable seal and are used in all hydraulic circuits to minimize the possibility of oil leaks.
Radiator Cleanout AccessRemovable covers on each side of the radiator guard provide access to the front of the radiator for cleanout with compressed air or pressure washer.
Extended Life Coolant (ELC)Extended Life Coolant (ELC) extends coolant life. A single addition of ELC Extender is the only maintenance required.
Separate Wiring HarnessesSeparate wiring harnesses connect all electrical components.
Environmentally Responsible Design
Caterpillar builds machines that help you create a better world.
Quiet CabThe cab is sound suppressed. The resiliently mounted engine and transmission result in less engine noise and vibration to the operator.
Dry MachineLubricant fill points and filters are designed to minimize spillage. O-ring face seals, XT hose and Cat hydraulic cylinders protect against leaks.
