Adjusting the Self-propel Drive

Service Interval: Every 75 hours
If the mower does not self-propel or has a tendency
to creep forward when the blade 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
(Figure 28).

1. Close the door in the mower housing and remove
the grass bag.
2. Rotate the control knob clockwise a half turn if the
mower does not self-propel. If the mower creeps
forward, rotate the knob a half turn counterclockwise
to loosen the belt (Figure 28).
3. Slowly pull the mower backward while you gradually
move the blade control bar toward the handle.
Note: The adjustment is correct when the rear
wheels stop turning and the blade control bar is
about one inch (2.5 cm) from the handle (Figure 29).

Adjusting the Blade Brake
Cable
Service Interval: Every 100 hours—Adjust the blade
brake cable.
Whenever you install a new blade brake cable assembly
or replace the belt, adjust the blade brake cable.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug.
3. Loosen the cable clamp screw until the brake cable
conduit slides (Figure 30).

4. Pull the cable to the remove slack, but do not
compress the spring. Tighten the cable clamp screw
to lock the adjustment in place.
Do not overtighten the blade brake cable.
Overtightening the blade brake cable could
cause the blade brake to come off of the brake
drum. If the brake does not contact the drum,
the blade will not stop rotating when you release
the control bar. A rotating blade could cause
serious personal injury.
• Each time you adjust the brake cable, ensure
that the brake stops the blade in 3 seconds
or less.
• If the blade does not stop rotating in 3
seconds or less, bring the mower to an
Authorized Service Dealer for inspection
and repair.
