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 27).

3. Slowly pull the lawn mower backward while
you gradually move the control bar toward the
handle.
Note: The adjustment is correct when the
rear wheels stop turning and the control bar
is about one inch (2.5 cm) from the handle
(Figure 28).

Note: If you remove the bearings from
the bearing/hub assembly, remove them by
pressing on the bearing spacer (Figure 29).
Assembling the Wheels
1. Position the tire onto one wheel half, aligning
the lugs on each (Figure 29).
2. Place the bearing/hub assembly into the center
hole of the wheel half. Ensure that the legs of
the hub are positioned over the flange of the
hole (Figure 29).
