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).

Figure 28

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.

6.Remove the upper belt cover (Figure 29).
