988 XE Wheel Loader

988 XE Wheel Loader

MOVE MORE MATERIAL EFFICIENTLY AND AT A LOWER COST

More Comfort – More Performance – More Versatility

  • UP TO 35% LESS FUEL CONSUMPTION

    Cycle time improvements in load & carry applications, along with improved stability and faster maneuvering with an optional load & carry counterweight result in increased productivity

  • LESS POWERTRAIN MAINTENANCE

    Reduce your powertrain maintenance by 50% with 2,000-hour service intervals and no component rebuild until 17,500 hours





     

  • MORE EFFICIENT DIG CYCLES

    Designed for easier operation with single pedal with dynamic braking and operator assist features, for faster training of new operators











     

  • UP TO 37% LESS CO2 EMISSIONS

    The 988 XE emits up to 37% less CO2 than the previous 988K.
