heavy mulching, reduce your width of cut by over-
lapping 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.

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.
NOTE:
Remove the blade adapter and check the
key inside hub of blade adapter. The key must be in
good condition to work properly. Replace adapter if
damaged.
TO REPLACE BLADE
1.Position the blade adapter on the engine cranks
haft. Be sure key in adapter and crankshaft keyway
are aligned.
2.Be sure the trailing edge of blade(opposite sharp
edge) is up toward the engine.
3.Install the blade bolt with spring washer into
blade adapter and crankshaft.
4.Use block of wood between blade and lawn mower
housing and tighten the blade bolt, turning clockwise.

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 ca-
tcher needs replacing, replace only with a manufa-
cturer approved replacement catcher. Give the lawn
mower model number when ordering.
DRIVE WHEELS ( power propelled)
Check rear drive wheels each time you mow to be
sure they move freely. The wheels not turning freely
means trash, grass cuttings, etc. may be inside the
drive wheel and dust cover area and must be cleaned
out to free drive wheels.If necessary to clean the d-
rive wheels, check both rear wheels.
