This tractor is equipped with an adjustable brake
system mounted on the right side of the transaxle

Road test tractor for proper stopping distance as
stated above. Readjust if necessary,
Tire Care
Maintain tire pressure in front at I4 PSI and rear tires
at 12 PS!.
Blade Sharpening
For best results mower blades must be kept sharp. The
blades can be sharpened with a few strokes of a file or
on a grinding wheel. We suggest they be sharpened
after every 25 hours of mowing. Do not attempt to
sharpen while on mower. If you mow in sandy soil
check the blades after each two mowings. The sand
wears the blades away rapidly,

When grinding, care should be taken to maintain
blade balance and the blade should be checked
for proper balance before remstaflation on mower.
Unbalanced or bent blade will cause excessive
vibration when running, and eventual damage to
mower or engine. Replace bent or damaged
blades.
To check blade balance, drive a nail into a beam
or watt. Leave about one inch of the straight nail
exposed. Place center hole of clean blade over the
head of the nail (Fig. 23). NOTE: CENTER HOLE
OF BLADE ON NAIL. IF BLADE iS PROPERLY
BALANCED, BLADE SHOULD REMAIN IN POSI-
TION SHOWN IN FIG. 23. IF EITHER END OF THE
BLADE MOVES DOWNWARD, BLADE tS NOT
BALANCED. SHARPEN THE HEAVY END UNTIL
BLADE tS BALANCED.
