859MH
Tracked Harvester
- Peak Power: 224 kW (300 hp) @ 1,900 rpm
- Max. Boom Reach: 8.84 m (29 ft. 0 in.)
- Tractive Effort: 373 kN (83,880 lbf)
Features
Engine power has increased significantly — by 25 percent — for superb multifunction performance
Longer, wider undercarriage maximizes stability no matter the terrain.If you’re working in really big timber or on hills, optional high-torque swing provides increased power, to boost productivity. Up to 45-percent more tractive effort increases capability for negotiating difficult or steep terrain, deep snow, and swamps.
RCS can be tailored to individual skill levels and specific harvesting conditions. 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.
Optional 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.
