The travel control console has adjustment fore and aft, and height.
For improved rear visibility during reverse operations, the operator can adjust seat 15° to the right.
Hydrostatic Steering System—Smooth, Powerful Turning
The Hydrostatic Steering System (HSS) is powered by an independent hydraulic pump with engine power transmitted to both tracks without power interruption on the inside track. When the machine turns, the outside track moves faster and the inside slower, for smooth, powerful turns. Counter-rotation is available for minimum turning radius providing excellent maneuverability. Shock-free steering reduces machine vibration and minimizes operator fatigue.
Fan speed is automatically controlled depending on coolant and hydraulic oil temperature. This saves fuel and provides great productivity with a quiet operating environment.
D85’s cab mounts use a newly designed cab damper which provides excellent shock and vibration absorption capacity with its long stroke. Cab damper mounts soften shocks and vibration while traveling over adverse conditions, which conventional mounting systems are unable to absorb. The cab damper spring isolates the cab from the machine body, suppressing vibration and providing a quiet, comfortable operating environment.
Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage.

Komatsu TORQFLOW transmission consists of a water-cooled, 3-element, 1-stage, 1-phase, torque converter and a planetary gear, multiple-disc clutch transmission which is hydraulically-actuated and force-lubricated for optimum heat dissipation. Gearshift lock lever and neutral switch helps prevent accidental starts.

Double-reduction final drive of spur and planetary gear sets to increase tractive effort and reduce gear tooth stresses for long final drive life. Segmented sprocket rims are bolt-on for easy replacement.
PCCS lever controls for all directional movements. Pushing the
PCCS lever forward results in forward machine travel, while pulling it
rearward reverses the machine. Simply tilt the PCCS lever to left to
make a left turn.
Hydrostatic Steering System (HSS) is powered by steering planetary
units and an independent hydraulic pump and motor. Counterrotation
turns are also available. Wet, multiple-disc, pedal-controlled
service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
