2.3.5 Fast Charging
Fast charging sends a relatively heavy initial current (50-60 amps) through the
battery. This will impart a fairly good charge in one to two hours.
As battery begins to take on a charge, charger current will automatically
decrease.
A fast charger will not bring a battery up to full charge. When the battery is
about 3/4 charged, use a slow rate to bring battery up to full charge.
If battery does not respond to a fast charge, try the slow charge method.
2.3.6 Jump Starting the Tractor
Cold weather reduces battery efciency. For example, at 32F, battery capacity
is reduced to 65%, and at 0F, capacity is reduced to 40%.
A 12-volt booster battery can be connected in parallel with battery on the
tractor to aid in cold weather starting. Heavy duty jumper cables will supply
signicantly more current than light duty cables.
To minimize risk of re or explosion when jump starting a
vehicle:
• Keep sparks and ame away from battery to avoid battery gas explosion.
• Do not allow the booster and dead vehicles to touch. Set park brakes and
turn both vehicle ignitions OFF.
• Connect one end of the positive (red) booster cable to the positive (+)
terminal on the dead battery and then the other end of this red cable to the
positive (+) terminal of the booster vehicle battery.
• Connect the end of the negative (black) booster cable to the negative
(-) terminal of the booster vehicle battery and the other end of this black
cable to a unpainted bolt or bracket on the dead vehicle (good ground)
located as far as possible from the dead battery to minimize the possibility
of igniting any hydrogen gas.
• Start the booster vehicle and let it idle for several minutes, then start the
dead vehicle. If the vehicle fails to start in a normal manner, discontinue
jump starting and service the vehicle for other problems.
• Once the dead vehicle is running, disconnect the booster cables in the
reverse order they were installed.
• Never allow booster cable ends to touch while connected to a battery.
