CUTTING BLADES

WARNING: 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.

WARNING: Periodically inspect the

blade adapter and/or spindle 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) then

gently flip the deck over to expose its un-

derside.

•

Place a block of wood between the center

deck housing baffle and the cutting blade

to act as a stabilizer. See Figure 22.

•

Use a 15/16" wrench to remove the hex

flange nut that secures the blade to the

spindle assembly. See Figure 22.

To properly sharpen the cutting blades, re-

move 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 23.
IMPORTANT: 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 23.
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.
IMPORTANT: Use a torque wrench to

tighten the blade spindle hex flange nut to

between

foot-pounds

and

foot-pounds.

BATTERY
The battery is sealed and is mainte-

nance-free. Acid levels cannot be checked.

•

Always keep the battery cables and termi-

nals clean and free of corrosive build-up.

•

After cleaning the battery and terminals,

apply a light coat of petroleum jelly or

grease to both terminals

•

Always keep the rubber boot positioned

over the positive terminal to prevent short-

ing.

IMPORTANT: If removing the battery for any

reason, disconnect the NEGATIVE (Black)

wire from it’s terminal first, followed by the

POSITIVE (Red) wire. When re-installing the

battery, always connect the POSITIVE (Red)

wire its terminal first, followed by the NEGA-

TIVE (Black) wire. Be certain that the wires

are connected to the correct terminals; re-

versing them could change the polarity and

cause damage to your engine’s alternating

system.
Charging the battery:
If the tractor has not been put into use for an

extended period of time, charge the battery

with an automotive-type 12-volt charger for a

minimum of one hour at six amps.
