As a further precaution, only charge the battery in a well
ventilated area.
Always shield eyes and protect skin and clothing when
working near batteries.
Batteries contain sulfuric acid and may emit explosive
gases. Use extreme caution when handling batteries. Keep
batteries out of the reach of child ren.
Battery Maintenance
The battery is filled with battery acid and then sealed at
the factory. However, even a "maintenance free" battery
requires some maintenance to ensure its proper life cycle.
Spray the terminals and exposed wire with a battery
terminal sealer, or coat the terminals with a thin coat of
grease or petroleum jelly, to protect against corrosion.
Always keep the battery cables and terminals clean and
free of corrosion.
Avoid tipping. Even a sealed battery will leak electrolyte
when tipped.
WARNING! Batteries contain sulfuric acid and may
emit explosive gases. Use extreme caution when
handling batteries. Keep batteries out of the reach
of children.
Battery Storage
1. When storing the tractor for extended periods, disconnect
the negative battery cable. It is not necessary to remove
the battery.
2. All batteries discharge during storage. Keep the exterior
of the battery clean, especially the top. A dirty battery will
discharge more rapidly.
3. The battery must be stored with a full charge. A discharged
battery can freeze sooner than a charged battery. A fully
charged battery will store longer in cold temperatures than
hot.

Recharge the battery before returning to service. Although
the tractor may start, the engine charging system may not
fully recharge the battery.
Hydrostatic Transmission
Your zero turn tractor is equipped with dual integrated
hydrostatic pumps/transaxles that are sealed and are
maintenance-free. However, the model ZT 54 is equipped with
a transmission oil expansion reservoir. Under normal operating
conditions, the oil level in the expansion reservoir does not need
to be checked and no additional oil is needed. If checking the
reservoir oil level, proceed as follows:
l_ll WARNING!
Check the oil level ONLY before
starting the tractor when the transmission oil is fully
cooled.
Pivot the operator's seat forward and clean the reservoir
cap and the area around the cap to prevent debris from
contaminating the transmission oil. See Fig. 6-3.

Figure 6-3
Turn the reservoir cap counterclockwise to re-move, then
check the oil level in the reservoir. Oil should be visible
at the bottom of the cup, but the oil level must NOT be
above 1/4"from the bottom of the cup. DO NOT FILL THE
RESERVOIR.
If necessary to add oil because of some type of leakage, use
a quality 20W50 motor oil and add only enough oil to bring
the level within 1/4"of the bottom of the reservoir. Reinstall
the cap and fully tighten.
TireMaintenance
Check the tire air pressure after every 50 hours of operation or
weekly. Keep the tires inflated to the recommended pressures.
Improper inflation will shorten the tire service life. See the tire
side wall for proper inflation pressures. Observe the following
guidelines:
Do not inflate a tire above the maximum pressure shown
on the sidewall of the tire.
Do not reinflate a tire that has been run flat or seriously
under inflated. Have a qualified tire mechanic inspect and
service the tire.
Lubrication
Using a pressure lubricating gun, lubricate the front castor
wheel axles and the front pivot axle with Cub Cadet 251H
EP grease after every 10 hours of service.
Periodically lubricate all other pivot points with a quality
lubricating oil.
