As steering clutch lever
1 is pulled, the piston of
steering valve 2
is moved in such a direction as
to apply hydraulic pressure to steering clutch
cylinder 3. By this hydraulic pressure, pressure
plate 4 is moved away from the staãk of disc
plates
5
and friction plates 6 to
disengage
the
clutch.
When the lever is further pulled, brake band 7 is
contracted to brake outer drum 8 to interrupt the
flow of power to the final drive.
It is possible to disengage the steering clutch
without braking for gradual turn or to disengage
it with braking for sharp turn.
As brake pedal 9 is depressed, the brake bands of
right-hand and left-hand clutches are simultane
ously contracted for braking independently of
the clutch control. This pedal can be used as a
parking brake if locked in fully depressed posi
tion by means of ratchet 10.
