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:
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!
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.
2.
Working from the middle of the tractor, pivot the idler
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.

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.
2.
Sitting behind the tractor facing forward, reach beneath
the tractor to grasp the belt at the front of the PTO pulley.
WARNING!
Use caution to avoid pinching your
fingers when rolling the belt off the PTO pulley.
3.
Pull the left side of the belt rearward and downward while
manually turning the PTO pulley to the right until the belt
rides out onto the edge of the lower sheave of the pulley.
NOTE: If pulling the right side of the belt, turn the pulley to
the left.
4.
While still holding the belt downward, continue turning
the PTO pulley until the belt is rolled off the pulley. Refer to
Figure 7-5.

5.
Lower the deck to the ground using the deck lift handle.
6.
Locate the LH and RH deck support pins on each side of the
deck. Pull the deck support pins outward and lock in the
disengaged position to release the deck from the tractor's
LH and RH deck lift arms. Refer to Figure 7-6.
7.
Raise the deck lift arms out of the rear hanger bracket slots
by raising the deck lift handle on the tractor to its highest
position. Refer to Figure 7-6.
8.
Slide the deck forward so that the deck front hanger rod can be
lifted out of the two slots of the front deck bracket. After
lifting the front hanger rod out of the slots, slide the deck
rearward so that the rod can no longer engage the slots.
9.
Using care to prevent the front hanger rod from falling
back into the deck bracket slots, carefully slide the cutting
deck (from the right side) out from underneath the tractor.
