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. Do not cut
more than 1" (2.5 cm) at any one time.
• 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.
Proper maintenance can prolong the life of
unit. The following charts show the
recommended service schedule. More
frequent service may be required due to
extreme working conditions (heavy loads,
high ambient temperatures, dusty conditions,
or airborne debris).
See the maintenance instructions in the
