When equipped with the Dedicated Travel System feature, a 330-hp engine option can be selected to further improve the performance and efficiency of the Travel System and all other machine functions as well.
The 859M 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.
Generous tractive effort enables reliable negotiation of difficult or steep terrain, deep snow, and swamps. Long and wide undercarriage combined with our industry-leading leveling system maximizes stability on steep slopes and other challenging terrain conditions.
RCS can be tailored to individual skill levels and specific harvesting conditions. Multiple RCS settings can be saved according to individual operator preferences.
Floor-to-ceiling front window, large side windows, skylight, and optional floor window (standard on levelers) significantly expand the view of the harvesting area and the work at hand.
The slope-monitoring system measures the actual ground-slope angle the machine is working on and displays it on the in-cab monitor, for more confident operation in tough steep-slope conditions.
From small stems to big timber, softwood to hardwood, level or sloped ground, the 859M has a variety of felling attachments that’s designed for your job. Choose among the FR21B, FS22B, FR22B, FR27, FS50, or FR50 to maximize overall production efficiency.
Take the guesswork out of planning, implementing, and monitoring your logging operation. The tools of our production-planning and -tracking system expand on the core technology features that come standard in every John Deere Forestry machine to unleash a powerful new array of possibilities:
