On each side of the mower deck, make sure that the
•
deck support pins are pulled outward and fixed in the
disengaged position. Refer to Figure 7-3.
Using the deck lift lever, lower the deck lift arms and
•
guide into the slots of the hitch brackets on the rear of
the mower deck.
From either side of the tractor, align the deck lift arm
•
hole with the deck support pin and release the pin so
that it goes through the deck lift arm. Repeat on the
other side of the tractor to secure the deck.
After first making sure the deck V-belt is still pulled
•
tight behind the deck idler pulleys, route the deck belt
rearward above the spacer between the two front drive
transmissions and toward the PTO pulley on the bottom
of the engine.
Using the deck lift handle, raise the deck to the posi-
•
tion that gives you the most horizontal run of the belt
between the deck pulleys and the PTO pulley on the
bottom of the engine.
Remove the wire tie, string, or clamp holding the V-belt
•
behind the deck idler pulleys. Then roll the belt onto
the PTO pulley and place the narrow side of the left run
of the belt in the V-idler pulley.
Pivot the idler bracket handle fully rearward and hold in
•
position while routing the backside of the left run of the
V-belt around the inside of the flat idler pulley. Refer to
Figure 7-2.
WARNING!:
The idler bracket is under spring
tension, use caution to avoid pinching your
fingers when installing the belt onto the idler
bracket pulleys
.
After making certain the V-belt is properly placed in the
•
PTO pulley and idler pulleys, carefully pivot the idler
bracket handle forward to tension the belt.
Removing the Deck Frame and Mower Deck
WARNING:
Do not operate the tractor without
an approved attachment installed on the front
of the tractor. Doing so could affect the trac-
tor’s stability and could cause an accident.
When replacing the mower deck with an optional attach-
ment, the mower deck and deck frame should be removed
from the tractor together. Proceed as follows:
WARNING!
Disengage the PTO, release the
forward or reverse control pedal, engage the
parking brake, stop the engine and remove
the key to prevent unintended starting.
Using the deck lift lever, place the mower deck in the
•
position that results in the most horizontal run of the
deck drive belt between the deck pulleys and the PTO
pulley on the bottom of the engine.
From the left side of the tractor, grasp the idler bracket
•
handle and pivot it rearward to relieve tension from the
deck drive belt. Remove the belt from the V-idler pulley
and flat idler pulley by pulling the belt downward. Care-
fully release the idler bracket handle. See Figure 7-2
From the left of the PTO pulley, pull the left side of
•
the drive belt downward and roll the belt off the PTO
pulley. Refer to Figure 7-2. Use the deck lift lever to fully
lower the deck.
To reduce the possibility of the deck drive belt disengag-
•
ing the spindle pulleys beneath the deck cover, grasp the
two sides of the deck belt just behind the belt keepers on
the two rear deck idler pulleys and pull the belt rearward.
Pinch the two sides of the belt together just behind the
rear most belt keeper and use a wire tie, string, or some
type of spring clamp to temporarily hold the two sides
of the belt together while removing the deck and deck
frame.
From either side of the tractor, just behind the mower
•
deck, disconnect the tractor lift link from the deck lift
arm by removing the internal cotter pin and withdraw-
ing the clevis pin. See Figure 7-7. Move to the other side
of the tractor and disconnect the lift link on that side in
the same manner.
Figure 7-7
On the left side of the deck frame, locate the safety
•
electrical harness connection. Spread the lock tabs on
the harness connector and disconnect the deck frame
safety harness. See Figure 7-8.
