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
Service Dealer.
Deck Removal
Remove the mower deck from the tractor as follows:
Move the tractor to a level surface, disengage the PTO, stop
1.
the engine, and set the parking brake.
Move the deck gauge wheels or rollers to their highest
2.
setting (lowest deck setting).
Remove the ‘V’ belt from the PTO pulley, located on the
3.
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
1.
that provides the most horizontal run of the belt between
the deck idler pulleys and the PTO pulley on the bottom of
the engine.
Working from the middle of the tractor, pivot the idler
2.
bracket and movable idler pulley rearward away from the
backside of the ‘V” belt just far enough to lift the belt up
and over the idler pulley. See Figure 7-4.
From beneath the rear of the tractor, slide the belt off of the PTO
