Benefits & Features

MAXIMIZE PERFORMANCE

    • Tandem engine machines improve cycle times on grades and in slippery underfoot conditions. Also improves the machine's loading characteristics in tough materials like clay.
    • Transmission Torque Converter - Increases rim pull and shortens load times, and eliminates engine stall to efficiently deliver power to the ground and move more dirt.
    • An auger mechanism in the bowl improves self-loading capabilities by lifting material off of the cutting edge and carrying it to the top of the load.

BUILT TO PERFORM

    • Proven Cat engines provide the power and torque rise for excellent lugging in tough loading conditions.
    • Variable injection timing and duration improve fuel efficiency and cold starting, decrease smoke and emissions.
    • Throttle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.
    • Throttle lock allows the operator the capability of locking both engines at any operating level.
    • Directional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.
    • Controlled throttle shifting increases drive train life by reducing the fuel injection rate just prior to shifting.
    • The aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.
    • Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.
    • Laminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.
    • Eight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.
    • Top gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.
    • The hydraulic retarder extends brake life when working on severe, downhill slopes.
    • Scraper driveline guard protects the output case, differential and ejector cylinder to help minimize driveline maintenance costs.

OPERATOR COMFORT AND CONTROL

    • Standard rubber-mounted cab reduces noise and vibration for comfortable, shift-long operation.
    • Hydraulic servo-steering system provides low-effort automotive feel and excellent maneuverability.
    • Tilt steering column adjusts to five different positions for operator comfort and control.
    • A suspension seat delivers a comfortable ride.
    • The Electronic Monitoring System checks important machine systems and provides a three-level warning.
    • Air conditioning to keep the operator comfortable.
    • The electronically controlled cushion hitch design dampens shocks to provide a smoother ride, and locks down for positive control of the cutting edge during loading and dumping.
