PERFORMANCE AND PRODUCTIVITY

  • Cat C9.3 engine delivers the performance needed to maintain consistent grading speeds for maximum productivity.
  • Latest engine technology optimize productivity, fuel efficiency, reliability, life and minimize emissions.
  • Hydraulic demand fan automatically adjusts speed according to engine cooling requirements. When cooling demand is reduced, you benefit from more power to the ground and improved fuel efficiency.
  • Engine Idle Shutdown Timer is software-enabled by your Cat dealer to shut down the engine after a set period of time to save you fuel and help reduce emissions.
  • Optional Reversing Fan, clears debris on-the-go.
  • TheMotor Graders give you efficiency and longevity in your most demanding applications.
  • Standard Automatic Differential Lock/Unlock unlocks the differential during a turn and re-locks when straight for easier operation and to help protect the power train.
  • Full Electronic Clutch Pressure Control system optimizes inching modulation for smooth shifts and directional changes, reducing stress on gears.
  • Programmable AutoShift option simplifies operation by allowing the operator to program the transmission to shift at optimal points to match your application.
  • Eco Mode can be engaged for up to 10% fuel savings depending upon application.
  • Power Shift Countershaft Transmission is matched to the Cat engine to maximize power to the ground.
  • Wide operating gear range for maximum productivity.
  • Engine Over-Speed Protection prevents downshifting until an acceptable safe travel speed has been established.
  • Sealed spindle keeps front axle bearings lubricated and protected from contaminants. The Cat “Live Spindle” design places the larger tapered roller bearing on the outside, where the load is greater, extending bearing life.
  • Bolt-on modular rear axle improves serviceability and contamination control with easy access to differential components.
  • Oil-bath, multi-disc service brakes are hydraulically actuated for smooth, predictable braking and lower operating costs. Brakes are located at each tandem wheel and have a large total brake surface area to give you dependable stopping power and longer life.
  • Emissions technology is transparent with no action required from the operator or need to stop. Regeneration runs automatically at cold start-up and, if needed, in the background while you work.
  • Reaching Tier 4 Final standards only required one additional system to the proven Cat emission strategy - Selective Catalytic Reduction (SCR).
  • SCR utilizes Diesel Exhaust Fluid (DEF), conveniently filled from ground level when re-fueling.
  • A gauge on the dash shows your fluid level.
  • At shutdown, a pump automatically purges the DEF lines.
  • If the engine/aftertreatment temperatures are high, a Delayed Engine Shutdown will activate automatically to cool the machine and then purge the lines.

BUILT FOR LONG TERM PRODUCTION

  • Caterpillar designs motor grader frame and drawbar components to give you performance and durability.
  • The one-piece forged steel circle stands up to high stress loads, and a sacrificial wear system helps keep your service time and costs down.
  • Articulation hitch features a large tapered roller bearing to carry loads evenly and smoothly. It is sealed to prevent contamination and a locking pin prevents articulation during service or transport.
  • The drawbar, circle and moldboard make it easy for you to keep the components tight.
  • Shims and patented top-adjust wear strips are easy to add or replace, reducing downtime.
  • Durable nylon composite wear inserts maximize circle torque and component life.
  • Wear strips between the blade mounting group and moldboard can be easily adjusted and replaced.
  • Shim less Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control.
  • An aggressive blade angle, optimized moldboard curvature and large throat clearance help you work more efficiently by allowing material to roll more freely along the blade.
  • Heat-treated rails, hardened cutting edges and end bits, and heavy duty bolts to give you greater moldboard reliability and long service life.
  • Link bar allows extreme moldboard positioning for easier bank sloping and ditch cutting/cleaning.
  • Proven load-sensing hydraulic system and advanced electro-hydraulics give you superior implement control and responsive performance that makes operator's jobs easier. Continuously matching hydraulic flow/pressure to power demands creates less heat and reduces power consumption.
  • Consistent, Predictable Movement - Proportional Priority Pressure-Compensating (PPP-C) valves have different flow rates for the head and rod ends of the cylinder, so you can count on consistent, predictable implement response.
  • Balanced Flow - Hydraulic flow is proportioned to give you confidence that all implements will operate simultaneously without slowing the engine or speed of some implements.
  • Blade can float freely under its own weight. By floating both cylinders, the blade can follow the contours of the ground. Floating only one cylinder permits the toe of the blade to follow a hard surface while the operator controls the slope with the other lift cylinder.
  • Large, separate hydraulic oil supplies prevent cross-contamination and provide proper oil cooling, reducing heat build-up and extending component life.
  • Cat XT™ hose allows high pressures for maximum power and reduced downtime.
