Benefits & Features
OPERATOR COMFORT AND CONTROL
- Isolation-mounted, pressurized cab reduces noise and vibration.
- Large, single pane windows offer excellent views all around the machine for productivity and safety.
- The Comfort Series seat is offset by 15 degrees for better visibility.
- Adjustable seat and armrests ensure comfort when working on steep grades or slopes.
- Display is easy to read, even in direct sunlight.
- Ergonomically designed controls for low-effort and ease of operation.
- Decelerator pedal gives full control of engine speed when the rocker switch is in the high idle position.
- A single-handle control performs steering and gear selection.
- Tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines.
- Differential Steering provides the finest modulation in the industry.
PERFORMANCE AND PRODUCTIVITY
- Precise controls optimize power and fuel efficiency.
- Differential steering maintains power to both tracks while turning. When one track speeds up, the other slows down an equal amount. Maneuverability - especially with large blade loads - is improved, as well as cycle times.
- Unique Cat torque divider sends 70 percent of engine torque through a converter and 30 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication.
- Planetary power shift transmission includes three speeds forward and three speeds reverse, featuring thick, large diameter, high capacity, oil-cooled clutches. These clutches provide higher torque capacity and increase service life.
- Modular transmission and differential slide into rear case for servicing ease, even when a ripper is installed.
BUILT FOR LONG TERM PRODUCTION
- Rugged frame absorbs high impact shock loads and twisting forces.
- Dozer pivot shaft runs through the mainframe and connects the roller frame for independent oscillation.
- Pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort.
- Tag-link design mounts the blade closer to the machine for excellent maneuverability, machine balance and blade penetration.
- Elevated sprocket design optimizes machine balance for best possible performance in each application. And, it keeps machine center of gravity low, offering excellent stability, balance and traction.
- Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer life.
- Modular power train components make it quick to remove and repair the transmission, final drives, steering differential or brakes.
- Modular undercarriage components simplify service. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components, reducing owning and operating costs, and raw materials and natural resources.
