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 cause damage to your engine’s alternating system.

IMPORTANT:

1.Battery wires must be connected to the correct terminals. Reversing them could change the polarity and damage engine’s alternating system.

2.Do not jump-start a damaged battery.

3.When storing the battery, disconnect the negative terminal and store with full charge.

CHARGING

If the unit 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.

WARNING: Do not use the tractor battery to start other vehicles.

Cleaning the battery

Keep the terminals and the top of the battery clean and free from corrosion. Clean the battery with baking soda and water or a commercial battery cleaner. If nece- ssary, scrape the battery terminals with a wire brush to remove deposits. Coat terminals and exposed wiring with grease or petroleum jelly to prevent corrosion.

CAUTION: Do not allow any cleaning solution to get inside the battery.

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.

FUSES

Two fuses are 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. See Figure 18.

GOODBAD

Figure 18

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

The other can be found under the seat mounted to the inside of the tractor frame next to the battery tray. Pull the fuse out and inspect it to determine if it is good or blown.

WARNING: Always use a fuse with the same amperage capacity for replacement.

CUTTING DECK REMOVAL

To properly remove the cutting deck, proceed as follows:

•Place the PTO/Blade Engage knob (or lever) in the disengaged (Blade Stop) position and engage the parking brake.

•Lower the deck by moving the deck lift lever into the bottom notch on the right fender.

•Remove the PTO belt from around the electric PTO clutch and from around the PTO idler pulley(s).

NOTE: The deck belt on the deck does NOT need to be removed in order to remove the deck.

•Looking at the cutting deck from the left side of the tractor, locate the deck support pin on the rear left side of the deck.

•Pull the deck support pin outward to release the deck from the deck lift arm. See Figure 19.
