ADJUST BRAKES
NOTE: The traction belt must disengage as the brake starts
to engage.
1. Turn off the engine, remove the key and allow unit to
cool.
2. If brakes do not disengage fully when traction belt is
engaged, the brakes are too tight. Disconnect trunnion
from the clutch weldment and turn the trunnion up the
brake rod to reduce braking. Reconnect the trunnion to
the clutch weldment (Figure 10).
3. If brakes do not engage fully when traction belt is
disengaged, the brakes are too loose. Disconnect
trunnion from the clutch weldment and turn the
trunnion down the brake rod to increase braking.
Reconnect the trunnion to the clutch weldment
(Figure 10).
4. Start engine and test in low gear for proper brake
engagement.
