0 Keep tires free of gasoline, oil, or insect control chemi­
cals which can harm rubber .

BLADE CARE
For best results mower blades must be kept sharp. Re­
place bent or damaged blades.
BLADE REMOVAL (See Fig. 13)
» Raise mower to highest position to allow access to
blades.
» Remove hex bolt, lock washer and flat washer securing
blade.
® Install new or resharpened blade with trailing edge up
towards deck as shown.
• Reassemble hex bolt, lock washer and flat washer in
exact order as shown.
» Tighten bolt securely (30-35 Ft. Lbs. torque).
IMPORTANT: BLADE BOLT IS GRADES HEATTREATED
NOTE: We do not recommend sharpening blade - but if you
do, be sure the blade is balanced.
TO SHARPEN BLADE (See Fig. 14)
Care should be taken to keep the blade balanced. An
unbalanced blade will cause excessive vibration and even­
tual damage to mower and engine.
“ The blade can be shar pened with a file or on a grinding
wheel. Do not attempt to sharpen while on the mower.
° To check blade balance, you will need a 5/8" diameter
steel bolt, pin, or a cone baiancer. (When tisihg a cone
balancer, foliow the instructions supplied with bal­
ancer.)
» Slide blade on to an unthreaded portion of the steel bolt
or pin and hold the bolt or pin parallel with the ground.
If blade is balanced, it should remain in a horizontal
position. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced,
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
BATTERY (See Fig. 15)
Your tractor has a battery charging system which is suffi­
cient for normal use. However, periodic charging of the
battery with an automotive charger will extend its life.
» Acid solution level in each battery cell should be even
with bottoms of vent wells. Add only distilled or iron free
water if necessary. Do not overfill.
® Keep battery and terminals clean.
» Keep battery bolts tight.
“ Keep vent caps tight and small vent holes in caps open.
- Recharge at 6 amperes for 1 hour.

the battery to “leak" power.

tery cable and remove battery from tractor.

baking soda to one gallon of water. Be careful not to get
the soda solution into the cells,
