KEY FEATURES

  • Engine power has increased significantly - by 25 percent - for superb multifunction performance.
  • A variety of boom sets and harvester heads can be combined to optimize productivity across a wide range of conditions.
  • Longer, wider undercarriage maximizes stability no matter the terrain.
  • If you're working in really big timber or on hills, standard high-torque swing provides increased power, to boost productivity.
  • Rapid Cycle System (RCS) now standard uses a single, easy-to-operate joystick to quickly and simply controls all boom functions.
  • Closed-loop hydrostatic drive boosts multifunctioning even more, particularly on slopes and in rough terrain. Adjust priority between track drive and other hydraulic functions to match site conditions and your operator style or preference.
  • Up to 45-percent more tractive effort increases capability for negotiating difficult or steep terrain, deep snow, and swamps.

PRODUCTIVITY

  • Rapid Cycle System (RCS) can be tailored to individual skill levels and specific harvesting conditions, from large single-tree harvesting to high-speed, multistem cutting.
  • Press a single button to engage RCS mode. Conditions don't suit the fast, parallel motion of the boom? Turn RCS off with another touch of a button.
  • Multiple RCS settings can be saved according to individual operator preferences. Novices may prefer a slower, more methodical pace, while highly skilled pros may want faster response.

CAB COMFORT

  • Fully adjustable armrests, including mounted keypads, provide fingertip control of all machine functions. Fully adjustable air-cushioned seat provides exceptional daylong comfort in the climate-controlled cab.
  • Sealed touchpad keeps out dust, moisture, and debris, minimizing wear. Proven marine-grade control center eliminates rocker switches, numerous wires, and unsealed connections, and lasts up to 10 times longer than standard dash switches.
  • Floor-to-ceiling front window offers 44-percent-more window area, providing an outstanding view to the cutting area.
  • Improved stability and increased engine horsepower help you make quick work of the woods in all conditions.

UPTIME

  • Field-proven boom design is transplanted from our larger 900M- and 900MH-Series models. All booms are stronger and more robust, with thicker plates and larger pins and bushings to ensure long life.
  • Fuel-tank capacity has been increased by over 50 percent (to 230 versus 154 gal. on comparably sized machines) to extend intervals between fill-ups, allowing you to run up to 24 hours without refueling.
  • Optional undercarriage-mounted toolbox provides convenient storage for tools, additional saw bars, and other spare parts, minimizing trips back to the service truck.
  • Through-nose plumbing option routes hoses up and out of harm's way to extend hose life, increasing uptime and reducing operating costs.

MAINTENANCE/LOW DAILY OPERATING COSTS

  • Easy access to service components helps ensure daily checks and preventative maintenance get done on schedule, minimizing costly repairs down the road.
  • Reversing fan automatically reverses airflow to eject debris from the cooler cores, conserving power and fuel. Variable-speed fan runs only as fast as needed, or if conditions demand more frequent cleaning, simply press a button to actuate the reversing cycle.
  • 800M- and 800MH-Series machines share many common components - including the engine, undercarriage, booms, and cab - with their 900M- and 900MH-Series counterparts, simplifying maintenance and repairs when needed.
