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.
If you have a recurring problem with blown fuses, have the
tractor's electrical system checked by your Troy-Bilt 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
Troy-Bilt Service Dealer.
Deck Removal
Remove the mower deck from the tractor as follows:
1. Move the tractor to a level surface, disengage the PTO, stop
the engine, and set the parking brake.
2. Move the deck gauge wheels or rollers to their highest
setting (lowest deck setting).
3. 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
1. 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.
