850C
Type ................................................................................................John Deere 6081A with altitude-compensating turbocharger; aftercooled
Engine power ..................................................................................185 SAE net hp (138 kW) / 192 SAE gross hp (143 kW) @ 1,800 rpm
Cylinders .........................................................................................6
Displacement ..................................................................................494 cu. in. (8.1 L)
Fuel consumption, typical ................................................................4.6 to 7.0 gal./hr. (17.4 to 26.5 L/h)
Maximum net torque .......................................................................601 lb.-ft. (815 Nm) @ 1,300 rpm
Lubrication ......................................................................................pressure system with full-flow spin-on filter and oil-to-water cooler

Transmission
automatic, dual-path, hydrostatic drive; load sensing feature automatically adjusts speed and power to match changing load conditions; each individually controlled track is powered by a variable displacement piston pump and motor combination; travel speeds (forward and reverse) infinite to 6.8 mph (0 to 11 km/h); ground-speed selection buttons on single-lever steering and direction control; independently selectable reverse speed ratios 80%, 100%, 115%, or 130% of forward ground speed; decelerator pedal controls ground speed to dead stop
Final Drives
double-reduction, planetary final drives transfer torque loads over three gear sets; mounted independently of track frames and dozer push frames for isolation from shock loads
Steering
single-lever steering, direction, and ground-speed control provides smooth metered turns; full power turns, counterrotation, and infinitely variable track speeds provide unlimited maneuverability and
optimal control; hydrostatic steering system eliminates steering clutches and brakes
Brakes
hydrostatic (dynamic) braking stops machine when the direction/steering control lever is moved to neutral, the decelerator is depressed to the end of travel, or the brake pedal is depressed
Automatic Parking Brake
this safety feature engages wet, multiple-disk brakes automatically whenever the engine stops, the operator applies the brake pedal, or the neutral start lever lock is in stop position; machine cannot be
operated with brake applied
