Adjusting the Self-propel
Drive
If the lawn mower does not self-propel or has a
tendency to creep forward when the control bar is
more than 1-1/2 inches (3.8 cm) from the handle,
adjust the wheel drive control knob on the rear of
the gear box.
1. Close the door in the lawn mower housing and
remove the grass bag.
2. Rotate the control knob clockwise a half turn
if the lawn mower does not self-propel. If the
lawn mower creeps forward, rotate the knob a
half turn counterclockwise to loosen the belt
(Figure 31).
