MAINTENANCE
Battery Removal and Installation
A CAUTION
• Before working on, or near, the electrical sys­
tem, shut the engine off, allow it to cool, dis­
connect the spark plug wire and prevent it from
touching the spark plug. Remove the Engine
Ignition key from the keyswitch.
• Remove all rings or other metal jewelry.
Failure to do this could result in personal injury
or property damage.
ACAUTION
The mower’s battery contains sulphuric acid and
other toxic materials.
• Do not damage the battery case. If the case
is broken or damaged, avoid contact with
battery contents.
• Dispose of battery properly. Check with local
authorities for proper disposal methods.
Failure to follow these instructions could result in
personal injury or property damage.
To remove the battery:
1. Use a 1 / 2 -inch wrench to remove the two bolts that
attach the rear of the hood to the rear hood. Then
loosen the four bolts (two on each side) that secure
the sides of the hood to the right and left frame
plates. Remove the hood.
2. From behind the rear hood, disconnect the plug
on the battery leads from the plug on the mower
wiring harness.

5. Carefully remove the top battery vibration pad.
6. Lift the battery and bottom vibration pad up, out of
the mower.
To install the battery:
1. Inspect both of the battery’s vibration pads for
damage and deterioration. Replace them if necessary.
Also inspect the hole (in the left-hand side of the rear
hood) that the battery wires go through—there should
be a plastic grommet in this hole to prevent the bat­
tery wires from chafing and then short circuiting.
2. Fold the larger battery vibration pad around the
battery as shown in Photo 5-53.
3. Fold the smaller vibration pad over the top and
forward side of the battery as shown in Photo 5-53.
4. Place the battery in the battery bracket. Make sure
that the battery’s leads are on the left-hand side.
Insert the leads through the hole in the left-hand side
of the rear hood.

3. Push the battery leads and the plug forward,
through the hole in the left-hand side of the rear
hood.
4. Use a 5/16-inch wrench to remove the bolt that
secures the lower front end of the battery clamp to
the front of the battery bracket. Take the battery clamp
off the mower.
5. Place battery clamp over battery. Secure it to the
front of battery bracket with previously removed bolt.
6. If the battery needs to be charged, please refer to
“Battery Charging” on Page 40 of this Manual.
7. After the battery has been charged, reconnect the
plug on the end of the battery leads to the plug on the
mower’s wiring harness.
8. Reinstall the hood on the mower. Use a %-inch
wrench to securely tighten all six bolts that secure it. 41
