FOR BEST PERFORMANCE
Cut grass when it is dry.
Keep mower blades sharp.
Keep mower deck properly leveled.
Adjust antiscalp rollers to prevent scalping.

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.
