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 are outrunning expectations — again.

Built for the way you work. Ongoing input from Customer Advocate Groups (CAGs) helps make 800M- and 800MH-Series machines even more rugged and reliable. Reach beyond Surefooted stability Smart debris management New extended stick option (for 800MH models only) enables a longer reach to minimize the number of cut trails and maximize machine efficiency. Long, wide undercarriage provides solid balance to maximize stability, no matter the terrain. Designed to keep your workspace free and clear, the productivityboosting debris-management system is integrated into the hood and left-side guarding...

STANDOUT FEATURE COVER MORE AREA

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. Rapid Cycle System (RCS) combines automated fellinghead arm cycling with simple boom control — dramatically reducing operator fatigue while increasing efficiency and productivity. 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, multistem cutting. Operator-specific settings Selectable operation...

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 Sealed-switch module Expansive visibility Fully adjustable armrests enable fingertip control of all machine functions on tracked feller bunchers; on tracked harvesters keypads are mounted on the joystick. Fully adjustable air-cushioned seat provides outstanding 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,...

EXPECT MORE And then some. 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. Your latest great idea is a new extended stick option on 800MH models. More boom Field-proven boom design is transplanted from our larger 900M- and 900MH-Series models. All booms are robust, with thick plates and strong joints, for extended durability and wear life. Designed for use with smaller attachments, the new extended stick option (only on...
