Be sure to shut the engine off, remove 

ignition key, disconnect the spark plug wire(s) and 

ground against the engine to prevent unintended 

starting before removing the belt.

All belts on your tractor are subject to 

wear and should be replaced if any signs of wear are 

present.

The V-belt found on your tractor is specially 

designed to engage and disengage safely. A substitute (non-

OEM) V-belt can be dangerous by not disengaging completely. 

For a proper working machine, use factory approved belts.
To change or replace the deck belt on your tractor, proceed as follows:
1. 

Lower the deck by moving the deck lift lever into the 

bottom notch on the right fender.

2. 

Remove the belt guards by removing the self-tapping 

screws that fasten them to the deck. See Figure 7-7.

3. 

Remove the belt keeper rod from around the engine pulley.

Avoid the possibility of a pinching 

injury. Do not place your fingers on the idler spring 

or between the belt and a pulley while removing the 

belt.

5. 

Remove the deck belt from around all pulleys, including 

the deck idler pulley.

6. 

Route the new belt as shown in and Figure 7-7.

7. 

Remount the belt guards removed earlier.

NOTE: Several components must be removed and special tools 

(i.e. air/impact wrench) in order to change the tractor’s drive belt. 

See an authorized MTD Service Dealer to have your drive belt 

replaced or phone Customer Support as instructed on page 2 for 

information on ordering a Service Manual.
