Mower Belt Replacement

Note: It is not necessary to remove the mower to install a

new belt. However, for easier access mower can be

removed. See Mower Removal in the Operation section.

1. Park the tractor on a smooth, level surface such as a

concrete floor. Disengage the PTO, turn off the

engine and lock the parking brake. Remove the key.

2. If mower is not removed, lower the mower lift and

place the mower in the lowest cutting position.

3. Push the idler arm (A, Figure 50 or 51) to relieve belt

tension. Drop the belt from the PTO (electric clutch)

pulley.

IMPORTANT: Note the position of all belt guides relative

to the belt and pulleys before loosening.

4. Some Models. Loosen the belt stop bracket(s) (C) or

belt covers (C).

5. Remove the old belt and replace with a new belt.

Make sure V-side of belt runs in arbor pulley grooves

and the flat backside runs against the idler pulley.

6. Some Models. Position the belt stop bracket(s) (C) in

their original positions. There must be 1/8” clearance

between the belt stop and the pulleys.

7. Install mower on tractor if it was removed. See

Operation section.

8. Run the mower under no-load condition for about 5

minutes

To avoid damaging belts, DO NOT PRY

BELTS OVER PULLEYS.
