TORQFLOW TRANSMISSION
Komatsu’s 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. Joystick control of
gears (3 forward and 3 reverse) and directional steering changes.
Gearshift lock lever and neutral safety switch prevent machine
from accidental starts.

STEERING SYSTEM
Joystick controls for all directional movements. Pushing the joystick
forward results in forward machine travel, while pulling it rearward
reverses the machine. Simply tilt the joystick to the left to make a
left turn. Tilt it to the right for a right turn.
Wet, multiple-disc steering clutches are hydraulically loaded and
hydraulically released. Wet, multiple-disc brakes are spring-actuated
and hydraulically released.
Steering brakes also function as service and parking brakes.
