any adjustments to the unit.
Adjusting the Self-Propel
Drive
Note: Improper adjustment can cause transmission
failure.
1. If the lawn mower does not self-propel or has a
tendency to creep forward when the control bar
is released, adjust the transmission cable on the
deck.
2. If the lawn mower does not self propel, rotate
the transmission cable nuts clockwise 1/2 turn
to tighten the belt.
3. If the lawn mower creeps forward, rotate the
transmission cable nuts 1/2 turn counterclockwise
to loosen the belt.
4. If the lawnmower does not drive up slopes, you
may need to increase belt tension. Repeat step 2.
