Handle ControlsEngine ControlsCutting Height ControlsAdjusting Cutting HeightNOTE: 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. Highest cutting height for rear wheel is lever in furthest front position. Highest cutting height for front wheel is lever in furthest back position. Picture Note: Left front wheel lever shown Picture Note: Left front wheel lever shown To help adjust rear wheel levers:1.
