JOHN DEERE 850J WLT DOZER

Productivity

    * Turbocharged/after-cooled 6-cylinder John Deere PowerTech™ wet-sleeve diesel provides exceptional reliability, power, and torque.
    * Full-featured hydrostatic drive train delivers full power turns, infinite speed range, infinitely variable track speeds, and automatic load sensing.
    * Total Machine Control lets you precisely match machine response and operating characteristics to operator preferences for increased flexibility and productivity.
    * Standard, LT, WT, and LGP configurations are available with inside-mount power-angle-tilt and outside-mount straight and semi-U blades.
    * Purpose-built mainframes for PAT and outside-mount blades allow optimized component placement for uncompromised grading ability.
        

    Comfort

    * Cab-forward design positions the operator close to the front for a more stable ride and unsurpassed visibility behind, below, and beyond the blade.
    * Deluxe suspension armchair adjusts seven ways for all-day comfort. Adjustable armrests and foot pedals are standard.
    * Ergonomically correct joystick gives intuitive, low-effort control of steering, forward/reverse travel, and ground speed.
    * Exclusive TMC lets you customize decelerator mode and response, forward/reverse ground speed ranges, steering modulation, FNR shift rate, and forward/reverse speed ratios.

    Uptime/Service

    * Best-in-class service access, same-side daily servicing, and 500-hour engine and 2,000-hour transmission and hydraulic oil and filter service intervals increase uptime.
    * Separate hydraulic and hydrostatic reservoirs, eliminating the possibility of cross contamination.
    * Fluid sample ports, remote drive system test ports, and onboard diagnostic messaging allow quick troubleshooting.
    * Hydraulic-driven fan automatically speeds up or slows down, operating as needed to keep things cool. Helps conserve power and fuel, while reducing noise and radiator core wear.
    * Operator station tilts a full 70 degrees in only minutes for wide-open access to internal components.
