SERVICE AND MAINTENANCE
1. Remove the hex washer screw securing the battery hold-down bracket to
the frame. Then flip the battery hold-down bracket up to free the battery.
See Figure 28.

2. Remove the hex cap screw and sems nut securing the black negative battery
lead to the negative battery post (marked NEG). Move the cable away from
the negative battery post.
3. Remove the hex cap screw and sems nut securing the red positive battery
lead to the positive battery post (marked POS).
4. Carefully lift the battery out of the tractor.
5. Install the battery by repeating the above steps in the reverse order.
WARNING
Always connect the positive lead to the battery before connecting the
negative lead. This will prevent sparking or possible injury from an
electrical short caused by contacting the riding mower body with tools
being used to connect the cables.
Charging the Battery
1. Test and, if necessary, recharge the battery after the riding mower has been
stored for a period of time.
2. A voltmeter or load tester should read 12.6 volts (DC) or higher across the
battery terminals. See Figure 29.

3. Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps.
Servicing Electrical System
A fuse is installed to protect the riding mower’s electrical system from damage
caused by excessive amperage. Always use the same capacity fuse for replacement.
If the electrical system does not function, check for a blown fuse.
If you have a recurring problem with blown fuses, call 1-888-331-4569 to schedule
electrical system service from Sears Parts & Repair.
Relays and Switches
There are several safety switches in the electrical system. If a function of the safety
interlock system described earlier is not functioning properly, call 1-888-331-4569
to have the electrical system checked by Sears Parts & Repair.
Hydrostatic Transmission
Your zero turn tractor is equipped with dual integrated hydrostatic pumps/
transaxles that are sealed and are maintenance-free. However, this model 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:
WARNING
Check the oil level ONLY before starting the tractor when the transmission
oil is fully cooled.
1. 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 Figure 30.
Figure 30
2. 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 the “FULL COLD” line. See Figure 30. DO NOT FILL THE RESERVOIR.
3. 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 to the “FULL COLD” line. Reinstall the
cap and fully tighten.
NOTE: Prior to the initial operation of the tractor, the oil level in the reservoir
may be slightly higher than the maximum due to air in the oil lines.
Operation of the tractor will eventually purge the air from the lines and the
oil level will settle to the maximum.
