Maintenance
Adjusting the Self-propel Drive
If the 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 self-propel
drive.
1. Loosen the nut that secures the adjuster (Figure 28).

2. Nut 4. 1-1/2 inches (3.8 cm)
2. Turn the adjuster until you remove the slack in the
exposed cable (Figure 28).
3. Tighten the nut.
Note: To check the adjustment, slowly pull the
mower backward while you gradually move the
control bar toward the handle. The adjustment is
correct when the rear wheels stop turning and the
top of the control bar is about 1-1/2 inches (3.8 cm)
from the bottom of the handle.
Note: If the adjuster is fully extended and the
mower does not self-propel when the blade control
bar is 1-1/2 inches (3.8 cm) from the handle, you
will need to adjust the lower anchor bracket. Refer
to steps 4 to 9.
4. Move the adjuster to obtain the maximum slack in
the cable.
5. Remove the fuel tank.
Note: You do not need to disconnect the fuel line
from the fuel tank.
