Squeeze the drive clutch control against the upper handle of the mower to engage the drive mechanism
and move the wheels. Release the drive clutch control to slow down the mower when negotiating an
obstacle, making a turn, or stopping the mower.
WARNING: If you strike a foreign object, stop the engine. Remove wire from spark plug, thoroughly
inspect the mower for any damage, and repair the damage before restarting and operating the
mower. Extensive vibration of the mower during operation is an indication of damage. The unit
should be promptly inspected and repaired.
Using Mulcher (Optional Equipment)
For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck,
preventing proper mulching of grass clippings.
New or thick grass may require a narrower cut. The ground speed of the mower should be adjusted to the
condition of the lawn. If mowing has been delayed and the grass has been allowed to grow in excess of
4", mulching is not recommended. Mow using the grass bag (if so equipped) to reduce the grass height to
3-1/4" maximum before mulching.
SECTION 10: ADJUSTMENTS
WARNING: Always stop the engine and disconnect the spark plug wire before performing any
adjustments on your lawn mower.
Adjusting Cutting Height
IMPORTANT: All wheels must be placed in the same relative position. For rough or uneven lawns, move the
height adjustment lever to a higher position. This will help stop scalping of the grass.
There is an adjusting plate and thumb lever at each wheel to enable the operator to adjust the mowers
cutting height. Each adjusting plate has nine height positions. Height of cut will be changed when you move
the thumb lever from one hole to another within these nine positions.
Simply depress the lever towards wheel and move lever assembly to desired position. See Figure 14A.
For rough or uneven lawns, move the height adjustment levers to higher cutting height position.

Adjusting Handle Height
Your mower is shipped with the handle in the higher height position. To lower the handle height, proceed as
follows.
Remove the starter rope from the rope guide.
Remove the upper handle by removing the hand knobs and carriage bolts. Lay the upper handle out of
the way, being careful not to bend or kink the cables.
Remove the hairpin clips from the weld pins on the handle brackets. Refer to Figure 6B. Press out on the
