STEERING SYSTEM
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. Counter-
rotation 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.

TORQFLOW TRANSMISSION
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 safety switch prevent accidental starts.
