nance.
BRAKE OPERATION
If tractor requires more than six (6) feet stopping distance
at high speed in highest gear, then brake must be adjusted.
(See “TO ADJUST BRAKE” in the Service and Adjust

all

cals which can harm rubber.

Avoid stumps, stones, deep ruts, sharp objects and
other hazards that may cause tire damage.
NOTE:
To seal tire punctures and prevent flat tires due to
slow leaks, tire sealant may be purchased from your local
parts dealer. Tire sealant also prevents tire dry rot and
corrosion.

FIG. 9
TO SHARPEN BLADE (See Fig.
10)
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 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, ora cone balancer. (When using a cone
balancer, follow the instructions supplied with bal
ancer.)
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
•
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.
V-BELTS
Check V-belts for deterioration and wear after 100 hours of
operation and replace if necessary. The belts are not
adjustable. Replace belts if they begin to slip from wear.
