    Smooth boom control

    The 803M comes standard equipped with Smooth Boom Control (SBC), allowing machine movements to be controlled more effectively, delivering a smoother experience for the operator and less wear and tear on the machine over time.

    Sure-footed stability

    Generous tractive effort enables reliable negotiation of difficult or steep terrain, deep snow, and swamps. Long and wide undercarriage maximizes stability in all terrain conditions.

    Expansive visibility

    Floor-to-ceiling front window, large side windows, skylight, and optional floor window significantly expand the view of the harvesting area and the work at hand.

    Standard Rapid Cycle System (RCS)

    RCS can be tailored to individual skill levels and specific harvesting conditions. Multiple RCS settings can be saved according to individual operator preferences.

    Comfortable control
    • Ergonomically designed controls and seat with dual-density seat pan and contour plus updated armrest and suspension boost overall operator comfort.
    • Options such as heated-ventilated seat (HVS) and updated premium Bluetooth® radio with XM Satellite Radio ready from the factory take comfort to the next level.
