Servicing Electrical System
A fuse is installed to protect the tractor’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. See
Figure 7-2.
Figure 7-2
If you have a recurring problem with blown fuses, have the
tractor’s electrical system checked by your authorized MTD
Service Dealer
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, have the electrical system
checked by your authorized MTD Service Dealer.
Deck Removal
Remove the mower deck from the tractor as follows:
Move the tractor to a level surface, disengage the PTO,
stop the engine, and set the parking brake.
Move the deck gauge wheels or rollers to their highest
setting (lowest deck setting).
Remove the ‘V’ belt from the PTO pulley, located on the
bottom of the engine, using one of the following two
methods.
WARNING!: The muffler at the rear of the
tractor may be extremely hot, and could cause
serious burns. Use extreme caution when near
the muffler. Allow the muffler to fully cool
before removing the belt from the PTO pulley.
Releasing belt tension with the idler pulley.
Using the deck lift handle, raise the deck to the
position that provides the most horizontal run of the
belt between the deck idler pulleys and the PTO pulley
on the bottom of the engine.

Battery Removal
WARNING!: Battery posts, terminals and
related accessories contain lead and lead
compounds. Wash hands after handling.
The battery is located on the right/rear of the tractor
beneath the seat box frame. To remove the battery:
Remove the two hex tapping screws from the battery
holddown bracket and remove the bracket. Use care
to avoid losing the trim strip from the bottom of the
bracket. See Figure 7-1.
Figure 7-1
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.
Remove the hex cap screw and sems nut securing the
red positive battery lead to the positive battery post
(marked POS).
Carefully lift the battery out of the tractor.
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 tractor body with tools being
used to connect the cables.
Charging the Battery
Test and, if necessary, recharge the battery after the tractor
has been stored for a period of time.
A voltmeter or load tester should read 12.6 volts (DC) or
higher across the battery terminals.
Charge the battery with a 12-volt battery charger at a
MAXIMUM rate of 10 amps.
