Mowing Tips
Cut grass when it is dry.
Keep mower blades sharp.
Do not set cutting height too low. For tall
grass, mow twice.
Do not mow too fast.
Mow with engine at full throttle. Discharge
clippings into areas already cut.
Vary cutting pattern with each mowing.
NOTE: To prevent dirt and grass from
collecting on mower pan, avoid operating
over bare ground with only patches of grass.
WARNING: Improper operation
can lead to injury. Learn what the
controls do and how they work.
Thoroughly read and understand
entire Operator Manual.
