Operating Your Lawn Mower
Once the engine has started, squeeze the blade
control handle against the upper handle to run the
lawn mower.
Do not operate the mower without the mulching
cover, the grass catcher bag, or the discharge
chute properly installed.
Be sure that the lawn is clear of stones, sticks, wire,
or other objects which could damage lawn mower
or engine. Such objects could be accidently 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,
preventing proper discharge of grass clippings,
poor mulching conditions, and could cause you to
slip and fall. New grass, thick grass, or wet grass
may require a narrower cut.
For a healthy lawn, always cut off one-third or less
of the total length of the grass. Lawn should be
trimmed in fall as long as there is growth.
WARNING:
If you strike a foreign object,
stop the engine. Remove spark plug wire from
spark plug, thoroughly inspect the mower for
any damage. Repair the damage before
restarting and operating the mower. Extensive
vibration of the mower during operation is an
indication of damage.
Bagging Grass Clippings
You can use the grass catcher bag to collect clippings
while you are operating the mower.
Attach the grass catcher following instructions on
page 8 of this manual. Grass clippings will
automatically collect in the bag as you run mower.
Operate mower till the grass bag is full.
Stop the engine completely by releasing the control
handle. Make sure that the unit has come to a
complete stop.
Lift discharge door and pull grass bag up and away
from the mower to dispose of the grass clippings.
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.

Adjusting Cutting Height

Refer to height adjustments section of this manual on
page 14 for instruction on how to adjust the cutting
height and the handle height.
For best results in mowing, keep the cutting height
position high until you have determined which
cutting height is preferred.
