FOR BEST PERFORMANCE Cut grass when it is dry. Keep mower blades sharp. Keep mower deck properly leveled. Adjust anti-scalp rollers to prevent scalping. Do not set height of cut too low. For very tall grass, mow twice. Do not travel too fast. Mow with the engine set at full throttle. When mulching, only remove 1/3 of grass length per cutting. Discharge clippings into areas already cut. Vary cutting pattern with each mowing. Do not allow grass or debris to collect inside of mower deck. Clean after each use.
