Changing The Front Axle Oil; Servicing The Battery - Toro Groundsmaster 120 Operator's Manual

Changing the Front Axle Oil

After every 500 hours of operation, change oil in the front
axle.
1. Run machine before changing oil to warm oil. Warm
oil flows more freely and carries more contaminants
than cold oil.
2. Clean area around drain plug and place a drain pan
below drain plug on axle (Fig. 38).
3. Remove drain plug and allow oil to flow into drain pan
(Fig. 38). After oil is drained, reinstall drain plug.
4. Remove fill plug and fill to plug level with SAE EP-90
wt. oil (approximately 14.9cl (44 oz.)) (Fig. 38).

Servicing the Battery

Warning
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Service Interval/Specification
Check the electrolyte level in the battery every 50 hours.
Always keep the battery clean and fully charged. Use a
paper towel to clean the battery case. If the battery
terminals are corroded, clean them with a solution of four
parts water and one part baking soda. Apply a light
coating of grease to the battery terminals to prevent
corrosion.
Voltage: 12 v, 280 Cold Cranking Amps

Checking the Electrolyte Level
1. Raise seat and remove belt guard. See Removing Belt
Guard on page 21.
2. With the engine off, open the covers to see into the
cells. The electrolyte must be up to the lower part of
the tube (Fig. 39). Do not allow the electrolyte to get
below the plates. (Fig. 39).
3. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery,
page 33.
4. Reinstall belt guard. See Installing Belt Guard on page
21.

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. Clean the top of the battery with a paper towel.
2. Lift off the filler caps (Fig. 39).
3. Slowly pour distilled water into each battery cell until
the level is up to the lower part of the tube (Fig. 39).
Important
Do not overfill the battery because
electrolyte (sulfuric acid) can cause severe corrosion and
damage to the chassis.
4. Press the filler caps onto the battery.
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
0 C (32 F).
1. Raise seat and remove belt guard. See Removing Belt
Guard on page 21.
2. Remove the battery from the holder.
3. Check the electrolyte level; refer to Checking
Electrolyte Level.
