Always observe safety rules when performing any maintenance.
BRAKE OPERATION
If tractor requires more than six (6) feet stopping distance at high speed _n highest gear, then brake must be ad- justed. (See "TO ADJUST BRAKE" in the Service and Adjustments section of this manual),
TIRES
•Maintain proper air pressure in all tires
(See "PRODUCT SPECIFICATIONS" section of this manual).
•Keep tires free of gasoline, oil, or insect control chemicals which can harm
Ribber.
•Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.
NOTE: To seal tire punctures and prevent fiat tires due to slow leaks, tire sealant
may be purchased from your local parts dealer. Tire sealant also prevents tire dry rot and corrosion.

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing 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 eventual
damage to mower and engine.
•The blade can be sharpened with a file
or on a gdnding wheel. Do not attempt to sharpen while it is 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 bal- ancer, follow the instructions supplied
with balancer).
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 onto 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 ina horizontal position. If either end of the blade moves downward, sharpen the
heavy end until the blade is balanced. Center Hole
