• Always keep the battery cables and terminals 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 shorting.

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

NEGATIVE (Black) wire. Be certain that the wires are

connected to the correct terminals; reversing them

could change the polarity and result in damage to your

engine’s alternating system.

Charging

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.

WARNING: Batteries give off an explosive

gas while charging. Charge battery in a well

ventilated area and keep away from an open

flame or pilot light as on a water heater, space

heater, furnace, clothes dryer or other gas

appliances.

Jump Starting

WARNING: When removing or installing

the battery, follow these instructions to

prevent the screwdriver from shorting against

the frame.

IMPORTANT: Never jump your tractor’s dead battery

with the battery of a running vehicle.

• Connect end of one jumper cable to the positive

terminal of the good battery, then the other end to

the positive terminal of the dead battery.

• Connect the other jumper cable to the negative

terminal of the good battery, then to the frame of

the unit with the dead battery.

WARNING: Failure to use this procedure

could cause sparking, and the gas in either

battery could explode.

Cleaning

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.

Battery Failures

Some common causes for battery failure are:

• incorrect initial activation • undercharging

• overcharging • corroded connections

• freezing

These failures are NOT covered by your tractor’s

warranty.

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

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 21) 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 19.

• Use a 15/16" wrench to remove the hex flange nut

that secures the blade to the spindle assembly. See

Figure 19.

• 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 20.
