Adjusting Cutting Height

c CAUTION: Avoid injury! Rotating blades are dangerous and can cut fingers and toes. Stop engine and wait for blade to stop rotating before adjusting cutting height.

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.
