TRACTION CONTROL
Traction Control Operation
A belt transfers power from the engine to the
transmission. The tension on this belt determines
whether the unit will drive or not. Tensioning is
accomplished by tilting the transmission rearward.
The operator controls this by means of the black
control bar at the top of the handle. When the operator
brings the control bar up to the handle, a cable is
tightened and causes the transmission to rock
backwards. When the operator releases the control
bar, the transmission is allowed to
tilt
forward which
loosens the belt. A belt guide at the engine and another
on top of the transmission insure that the belt
adequately releases the pulleys. This provides positive
control.
Adjustment of the control bar is accomplished by
means of
a
jam and locknuts arrangement on the
traction cable on '88 and '89 units. '90 and newer units
use a fingertip adjustment near the control bar.
