USING YOUR ROTARY MOWER
,_ WARNING: Never operate your unit
without either the rear deflector or entire
grasscatcherassembly in place.
Be sure that lawn is clear of stones, sticks, wire, or
other objects which could damage lawn mower or
engine. Such objects could be accidentally thrown
by the mower in any direction and cause serious
personal injury to the operator and others.
For the best results,do not cut wet grass becauseit
tendstostickto the undersideof the mower,prevent-
ing proper discharge of grass clippings, and could
cause you to slipand fall. New grass, thickgrass or
wet grass may require a narrower cut. Blade speed
shouldbe adjustedto the conditionof the lawn.
For healthy lawn, never cut more than one-third
of the total length of the grass at any one cutting.
Lawn should be cut in the fall as long as there is
growth.
This moweris designedto be operated at fullthrottle
to giveyou the best cut and do the most effectivejob
of baggingthe cut grass.
A
WARNING: If you stdke a foreign
object, stop the engine. Remove wire
from spark plug, thoroughly inspect the
mower for any damage, and repair the
damage before restarting and operating
the mower. Extensive vibration of the
mower duringoperation is an indicationof
damage. The unit should be promptly
inspectedand repaired.
USING YOUR MULCHER
(Mulching Kit is Optional Equipment)
For effective mulching, do not cut wet grass
because it tends to stick to the underside of the
deck, preventing proper mulching of grass clippings.
New or thick grass may require a narrower cut. The
ground speed should be adjusted to the condition of
the lawn. If mowing has been delayed and the grass
has been allowed to grow in excess of 4", mulching
is not recommended. Mow using the grass bag (if
so equipped) to reduce the grass height to 3-1/4"
maximum before mulching.
