proper discharge of grass clippings, and could cause 
you to slip and fall. New grass, thick grass, or wet grass 
may require a narrower cut.
For a healthier lawn, never cut off more than one-third 
of the total length of the grass. Your lawn should be cut 
in the fall as long as there is growth. This mower is 
designed to be operated at full throttle to give you the 
best cut and do the most effective job of mowing or 
mulching.
WARNING: If you strike a foreign object,
stop the engine. Remove wire from the
spark plug, thoroughly inspect the mower
for any damage, and repair the damage
before restarting and operating the
mower. Extensive vibration of the mower during
operation is an indication of damage. The unit
should be promptly inspected and repaired.
Mulching
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 to reduce the grass height to 3 1/4” 
maximum before mulching.
SECTION 6: MAKING ADJUSTMENTS
WARNING: Do not at any time make any
adjustments without first stopping engine
and disconnecting spark plug wire.

located on the left side of the deck. The handle may be
