Using Rotary Mower
WARNING: Never operate your unit
without 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,
preventing 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.
Blade speed should be adjusted to the condition of
the lawn.
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 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 bagging the cut grass.
WARNING: 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 and operating the mower.
Extensive vibration of the mower during
operation is an indication of damage.
Using Mulcher (If equipped)
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
adjustment to lawn mower without first
stopping engine and disconnecting spark
plug wire.
Handle Height
Your mower is shipped with the handle in the higher
height position. To lower the handle height, proceed as
follows.
Remove the starter rope from the rope guide.
Remove the upper handle by removing the hand
knobs and carriage bolts. Lay the upper handle out
of the way, being careful not to bend or kink the
cables.
Remove the hairpin clips from the weld pins on the
handle brackets. Press outward on the legs of the
lower handle, and remove it from the mower
Turn the lower handle around so the notches on the
bottom of the lower handle are facing forward as
shown in Figure 16 . Reassemble, placing the
bottom holes in the handle over the weld pins in the
handle mounting bracket.
