slipping while cutting grass; and frayed edges, burn
marks, and cracks on the belt.

Replacing the Mower Belt

The signs of a worn belt include squealing while the
belt is rotating, blades slipping while cutting grass,
and frayed edges, burn marks, and cracks on the belt.
Replace the mower belt if any of these conditions are
evident.

1.

Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.

2.

Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.

3.

Lower the mower to the 76 mm (3 inches)
height-of-cut position.

4.

Remove the mower-deck curtain; refer to

Releasing the Mower-Deck Curtain (page 31)

.

5.

For each of the belt covers, loosen the 2 bolts,

but do not remove them.

6.

Slide the cover until it is clear of the bolts and lift
it up and out to remove it.

7.

Remove the floor pan to access the idler pulley.

8.

Using a spring removal tool, (Toro Part No.

the lowest height-of-cut.

10.

Remove the belt from the mower-deck pulleys
and remove the existing belt.

11.

Install the new belt around the mower pulleys
and the clutch pulley under the engine (

Figure

59

).

WARNING

The spring is under tension when
installed and can cause personal injury.

Be careful when removing the belt.

12.

Using a spring-removal tool, (Toro Part No.
92-5771), install the idler spring over the deck
post and placing tension on the idler pulley and
mower belt (

Figure 59

).

13.

Ensure that the belt is properly seated in all
pulleys.

14.

To install the belt covers, insert the tabs on the
each cover into the corresponding slots on the
deck bracket, ensuring that they seat.

15.

Rotate the cover to the deck and slide the
notches under the loosened bolts until they are
seated.

16.

Tighten the bolts to secure the cover to the deck.
