TRACKED FELLER BUNCHERS/HARVESTERS 803M/MH / 853M/MH / 859M/MH PROVEN PERFORMANCE

OUTRUN EXPECTATIONS.

When we designed our next-generation 800M- and 800MHSeries machines, we relied on the input of the people who run them every day. These job-proven midsize models have been redefining uptime, productivity, and low daily operating costs — in the woods and at the landing — because you wanted them to. THANKS TO YOU, these tracked feller bunchers and harvesters have outrun expectations — again.

Engine power Surefooted stability Smart debris management Powerful engine output adapts to the application, for reliable multifunction performance. Closed-loop hydrostatic drive Boost multifunctioning even more, particularly on slopes and in rough terrain. Adjust priority between track drive and other hydraulic functions to match site conditions and operator style or preference. Long, wide undercarriage provides solid balance to maximize stability, no matter the terrain. High-torque swing option If you're working in really big timber or on hills, high-torque swing — standard on harvester...

standout feature maximize productivity Rapid Cycle System. Faster, low-effort joystick control of all boom functions helps operators of 800M- and 800MH-Series machines be more productive. New Rapid Cycle System (RCS) combines automated felling-head arm cycling with simple boom control — dramatically reducing operator fatigue while increasing efficiency and productivity. ' . ■ I I § Adaptable to preferences and environments RCS can be tailored to individual skill levels and specific harvesting conditions, from large single-tree harvesting to high-speed, multi-stem cutting....

Room with a view. Spacious operator station was designed by loggers for loggers. It’s roomier and more comfortable, with ergonomically designed controls. And the view has to be seen to be believed, with significantly more window area, for improved visibility.

Low-effort control Fully adjustable armrests, including mounted keypads, provide fingertip control of all machine functions. Fully adjustable air-cushioned seat provides outstanding daylong comfort in the climate-controlled cab. Sealed-switch module 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. Expansive visibility Floor-to-ceiling front window significantly expands the view of the cutting area and the...

EXPECT MORE In the woods, uptime is the name of the game. That's why we went to our toughest customers, loggers just like you, to continually reinvent the rugged 800M and 800MH-Series Tracked Feller Bunchers and Tracked Harvesters. Robust booms Field-proven boom design is transplanted from our larger 900M- and 900MH-Series models. All booms are strong and robust, with thick plates and large pins and bushings, to extend wear life. Larger fuel tanks Fuel-tank capacity has been increased by over 50 percent (to 230 versus 154 gal. on comparably sized machines) to extend intervals between...

EASY MAINTENANCE Simplified serviceability Easy access to service components helps confirm daily checks and preventative maintenance get done on schedule, minimizing costly repairs down the road. Hydraulic reversing fan 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. Keep it clean Perforations in the hood and left-side guarding serve as a “first filter,” with the cooler cores...
