Benefits
Unmatched Durability
- The full box-section rear frame resists torsional shock and twisting forces.
- Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
- Optimized axle mounting results in increased structural integrity.
- Achieve longer component life with increased size of upper hitch pin, frame plate, and bearing.
- Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.
- Features fully enclosed hydraulic wet disc brakes for improved performance.
- Robust structures withstand the toughest conditions and multiple lifecycles to improve your bottom line.
- In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
Optimum Efficiency
- The Cat C18 engine is designed for maximum fuel efficiency in the most demanding applications.
- Experience reliable efficiency with complete control over injection timing, duration, and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).
- Best-in-class Cat planetary powershift transmission features consistent, smooth shifting and efficiency through integrated electronic controls.
- Extended engine life and improved fuel efficiency with reduced rated speed.
- Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS) provide precise rimpull control.
- Load sensing hydraulic steering system enables precise machine control for easier loading.
- Lock-up torque converter with advanced control of lock-up speed.
- On demand cooling fan protects investment and lengthens lifecycle.
- Fully integrated electronic engine controls provide quick response.

- Operators can easily enter and exit the cab with fold-up STIC steer/ armrest, reduced access stairway angles, and standard stairway lighting.
- Experience reduced vibrations with isolated cab mounts and seatmounted implement and steering controls.
- Reduced interior sound levels keep operators comfortable throughout their entire shift.
Improved Sustainability
- The engine is available in configurations that meet U.S. EPA Tier 4 Final and EU Stage V emission standards, or equivalent to U.S. EPA Tier 3 or U.S. EPA Tier 2.
- Automatic Engine Idle Shutdown conserves fuel when machine is not in use.
- Generate less waste with maintenance-free batteries.
- Maximize machine life and lower operating costs with Caterpillar Reman and Certified Rebuild programs, which utilize reused or remanufactured components for 40 to 70% cost savings.
- Retrofit packages from Caterpillar deliver new features to older machines to get the most from your investment.
Simplified Maintenance
- Machine features ground level or platform access to easily reach daily service points.
- Swing-out doors on either side of the engine compartment provide easy access to critical daily service checks.
- Ecology drains prevent spills and allow for easier service.
- Intuitive design includes ground level access to transmission control valves for safe and convenient service.
- Available in two scoop arrangements – wood chip and coal.
- Cat wood chip and coal scoops have the unique capability of maximizing your production by both dozing and carrying a load with each pass.
- A purpose built hydraulic system, optimized for use with this work tool, maximizes machine productivity and efficiency.
- Dual lift cylinders provide hydraulic lift capacity matched to the demands of the application.
- Can be equipped with optional ground level accessible swing-out reversing fan for quick inspection and easy cleanout.
- Equipped with underhood ventilation system which creates a neutral pressure environment to prevent wood chip ingestion from hood openings while providing fresh air to the alternator, electronics, and turbo.
- Extended top guard for increased capacity for wood chip scoops.
- Higher ground pressure decreases risk of fires and maximizes use of storage space.
- Less damage to coal or wood chips due to rubber tires.
- High ground speed provides ability to manage multiple piles.
