2. Look at the side of the battery. The electrolyte must be
up to the Upper line (Fig. 26). Do not allow the
electrolyte to fall below the Lower line (Fig. 26).

3. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery,
page 26.
Adding Water to the Battery
The best time to add distilled water to the battery is just
before you operate the machine. This lets the water mix
thoroughly with the electrolyte solution.
1. Remove the battery from the tractor; refer to Removing
the Battery, page 25.
Important
Never fill the battery with distilled water
while the battery installed in the tractor. Electrolyte could
be spilled on other parts and cause corrosion.
2. Clean the top of the battery with a paper towel.
3. Remove the vent caps from the battery (Fig. 26).
4. Slowly pour distilled water into each battery cell until
the electrolyte level is up to the Upper line (Fig. 26) on
the battery case.
Important Do not overfill the battery because
electrolyte (sulfuric acid) can cause severe corrosion and
damage to the chassis.
5. Wait five to ten minutes after filling the battery cells.
Add distilled water, if necessary, until the electrolyte
level is up to the Upper line (Fig. 26) on the battery
case.
6. Reinstall the battery vent caps.
Charging the Battery
Important
Always keep the battery fully charged
(1.260 specific gravity). This is especially important to
prevent battery damage when the temperature is below
32 F (0 C).

1. Remove the battery from the chassis; refer to Removing
the Battery, page 25.
2. Check the electrolyte level; refer to Checking the
Electrolyte Level, page 25.
3. Make sure that the vent caps are installed in the battery.
Charge the battery for 1 hour at 25 to 30 amps or
6 hours at 4–6 amps. Do not overcharge the battery.
4. When the battery is fully charged, unplug the charger
from the electrical outlet, then disconnect the charger
leads from the battery posts (Fig. 27).

5. Install the battery in the tractor and connect the battery
cables; refer to Installing the Battery, page 25.
Note: Do not run the tractor with the battery disconnected,
electrical damage may occur.
