Using Your Rotary Mower
WARNING:
either the rear deflector or entire grass catcher
assembly 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 best results, do not cut wet grass because it
tends to stick to the underside of the mower, and
could cause you to slip and fall. New grass, thick
grass or wet grass may require a narrower cut.
• For a 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 season as long as
there is growth.
an
WARNING:
mower during operation is an indication of
damage. If you strike a foreign object, stop
the engine. Remove wire from spark plug,
thoroughly inspect the mower for any
damage, and repair the damage before
restarting the mower.
Using the Mulcher
• 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.
