Adjusting Cutting Height
c CAUTION: Avoid injury! Rotating blades are dangerous. Before you adjust cutting height: Stop engine and wait for moving parts to stop.
|
NOTE: Adjust both levers to same height except for two lowest cutting heights (A and B on following chart). At two lowest cutting heights, raise rear lever one notch higher than front lever. This adjustment allows for increased air flow when bagging and side discharging, and provides a larger exit window for clippings when mulching.
Begin at upper cutting height, then adjust downward as desired, to avoid scalping lawn with too low a setting.
Picture Note: Front wheel shown in top photo.
Adjusting front wheel height:
1. Lift front of mower deck slightly with one hand to take some weight off wheels.
2. Move height adjustment lever to desired position with other hand.
Adjusting rear wheel height:
1. Lift lower handlebar slightly with one hand to take some weight off wheel.
2. Move height adjustment lever to desired position with other hand.
Adjusting Handle Height
Upper Handle:
NOTE: Upper handle height can be independently adjusted to two positions.
1. Remove knob (A) and bolt (B) from each side of upper handle.
2. Move handle to desired height.
3. Install bolt through matching holes in upper and lower handles on each side.
4. Install and tighten knob (A).
Lower Handle:
NOTE: Lower handle height can be independently adjusted to three positions.
1. Loosen knob (C) approximately 25 mm (1 in.) on each side of handle.
NOTE: Knob must travel within slotted adjustment brackets and come to rest within one of the three height setting positions (E) before tightening.
2. Pivot handle to a desired height within slotted adjustment bracket (D).
3. Tighten knob (C) on each side of handle.
