4. Open the cell covers to see into the cells. The
electrolyte must be up to the lower part of the
tube (Fig. 54). Do not allow the electrolyte to get
below the plates.
5. If the electrolyte is low, add the required amount
of distilled water; refer to Adding Water to the
Battery.
6. If the fluid level is correct, press the cell covers
onto the battery and replace the battery shield.
IMPORTANT: Keep the battery shield in
place to protect the battery from heat.

Adding Water to the Battery
IMPORTANT: Use only distilled water.
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. Clean the top of the battery with a paper towel.
2. Lift off the filler caps (Fig. 54).
3. Slowly pour distilled water into each battery cell
until the level is up to the lower part of the tube
(Fig. 54).
IMPORTANT: Do not overfill the battery
because electrolyte (sulfuric acid) can cause
severe corrosion and damage to the chassis.
4. Press the cell covers onto the battery.
5. Replace the battery shield.
IMPORTANT: Keep the battery shield in
place to protect the battery from heat.
6. Replace the front grill of the tractor, securing it
with the two previously removed screws and
