Failure to use this procedure

could cause sparking, and the gas in either
battery could explode.

Clean the battery by removing it from the tractor and 
washing with a baking soda and water solution. If 
necessary, scrape the battery terminals with a wire 
brush to remove deposits. Coat terminals and exposed 
wiring with grease or petroleum jelly to prevent 
corrosion.

Some common causes for battery failure are: 

• incorrect initial activation

• undercharging

• overcharging

• corroded connections

• freezing

Be sure to shut the engine off,

remove ignition key, disconnect the spark plug
wire(s) and ground against the engine to
prevent unintended starting before removing
the cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves or a rag to grasp the cutting
blade.

Periodically inspect the blade

spindles for cracks or damage, especially if
you strike a foreign object. Replace
immediately if damaged

.

The blades may be removed as follows.

•

Remove the deck from beneath the tractor, (refer to 
Cutting Deck Removal on page 19) then gently flip the 
deck over to expose its underside.

•

Place a block of wood between the center deck 
housing baffle and the cutting blade to act as a 
stabilizer. See Figure 16.

•

Use a 15/16" wrench to remove the hex flange nut 
that secures the blade to the spindle assembly. See 
Figure 16.

•

To properly sharpen the cutting blades, remove 
equal amounts of metal from both ends of the 
blades along the cutting edges, parallel to the 
trailing edge, at a 25° to 30° angle. See Figure 17.

 If the cutting edge of the blade has already 

been sharpened to within 5/8" of the wind wing radius, 
or if any metal separation is present, replace the blades 
with new ones. See Figure 17.

It is important that each cutting blade edge be ground 
equally to maintain proper blade balance. 

A poorly balanced blade will cause excessive vibration 
and may cause damage to the tractor and result in 
personal injury. The blade can be tested by balancing it 
on a round shaft screwdriver. Grind metal from the 
heavy side until it balances evenly. 

When replacing the blade, be sure to install the blade 
with the side of the blade marked ‘‘Bottom’’ (or with a 
part number stamped in it) facing the ground when the 
mower is in the operating position. 

 Use a torque wrench to tighten the blade 

spindle hex flange nut to between 70 foot-pounds and 
90 foot-pounds. 

A fuse is installed in your tractor’s wiring harness to 
protect the tractor’s electrical system from damage 
caused by excessive amperage. 

If the electrical system does not function, or your 
tractor’s engine will not crank, first check to be certain 
that the fuse has not blown. 

It can be found under the hood mounted behind the top 
of the dash panel on the support bar. 

Always use a fuse with the

same amperage capacity for replacement.
