nance,
BRAKE OPERATION

at high speed in highest gear, then brake must be adjusted,
(See TO ADJUST BRAKE” in the Service and Adjust­
ments section of this manual)
TIRES
" Maintain proper air pressure in all tires (See “PROD­
UCT SPECIFICATIONS" ОП page 3 of this manual).
* Keep tires free of gasoline, oil, or insect control chemi­
cals which can harm rubber.
* Avoid stumps, stones, deep ruts, sharp objects and
other hazards that may cause tire damage.

IMPORTANT:
BLADE BOLT IS GRADE 8 HEAT TREATED
NOTE: We do not recommend sharpening blade - but if you
do, be sure the blade is balanced-
TO SHARPEN BLADE (See Fig. 13)
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 sharpened 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 balancer (When using a cone
balancer, follow 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. 14)
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.
