MULCHING MOWING TIPS
•
The special mulching blade will re-cut the grass
clippings many times and reduce them in size so
that as they fall onto the lawn they will disperse into
the grass and not be noticed. Also, the mulched
grass will biodegrade quickly to provide nutrients
for the lawn. Always mulch with your highest engine
(blade) speed, as this will provide the best
re-cutting action of the blades.
•
Avoid cutting your lawn when it is wet. Wet grass
tends to form clumps and interferes with the
mulching action. The best time to mow your lawn is
the early afternoon. At this time the grass has dried
and the newly cut area will not be exposed to the
direct sun.
CUSTOMER RESPONSIBILITIES
IMPORTANT:
For best performance,
keep mower housing free of built-up
grass and trash. See “CLEANING” in customer
responsibilities section of this manual.
•
For best results, adjust the lawn mower cutting
height so that the lawn mower cuts off only the
top one-third of the grass blades. If the lawn is
overgrown it will be necessary to raise the height
of cut to reduce pushing effort and to keep from
overloading the engine and leaving clumps of
mulched grass. For extremely heavy mulching,
reduce your width of cut by overlapping previously
cut path and mow slowly.
•
Certain types of grass and grass conditions may
require that an area be mulched a second time to
completely hide the clippings. When doing a second
cut, mow across or perpendicular to the first cut
path.
•
Change your cutting pattern from week to week
mow north to south one week then change to east
to west the next week. This will help prevent matting
and graining of the lawn.
WARNING:
Make sure all operations are
performed while the engine is stopped.

MOWING TIPS
Under certain conditions, such as very tall grass,
it may be necessary to raise the height of cut to re-
duce pushing effort and to keep from overloading the
engine and leaving clumps of grass clippings. It may
also be necessary to reduce ground speed and /or
run the lawn mower over the area a second time.
For extremely heavy cutting, reduce the width of
cut by overlapping previously cut path and mow slowly.
For better grass bagging and most cutting condi
tions, the engine speed should be set in the fast position.
Pores in cloth grass catchers can become filled
with dirt and dust with use and catchers will collect
less grass. To prevent this, regularly hose catcher off
with water and let dry before using.
Keep top of engine around starter clear and clean
of grass clippings and chaff. This will help engine air
flow and extend engine life.
IMPORTANT:
FOR BEST PERFORMAN-
CE, KEEP MOWER HOUSING FREE OF
BUILT-UP GRASS AND TRASH. SEE

TO SHARPEN BLADE
NOTE:
We do not recommend sharpening blade but
if you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced.An
unbalanced blade will cause eventual damage to lawn
mower or engine.
The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen while on
the mower.
To check blade balance, drive a nail into a beam
or wall. Leave about one inch of the straight nail
exposed. Place center hole of blade over the head
of the nail. If blade is balanced, it should remain in
a horizontal position. If either ends of the blade moves
downward, sharpen the heavy end until the blade is
balanced.
GRASS CATCHER
The grass catcher may be hosed with water, but
must be dry when used.
Check your grass catcher often for damage or
deterioration. Through normal use it will wear. If
catcher needs replacing,replace only with a manu-
facturer approved replacement catcher.Give the
lawn mower model number when ordering.
