How to Put the Deck Belt on a MTD 754-0329A

If you own an MTD lawn tractor in the MTD 400 series or the MTD 600 series equipped with a 38-inch mower deck, when it comes time to replace the mower deck drive belt, you can use the belt "MTD 754-0329A" as a replacement. This belt replaces the OEM or original equipment manufacturer belts listed as 754-0329A and 754-0433. The only time you must replace the belt is when it dry-rots or starts to slip on the pulley system.

Things You'll Need

• Socket set
• New belt

Instructions

1. Park the mower on level ground, turn it off and remove the spark plug wire from the spark plug to disable the mower.

2. Locate and remove the mounting bolts from the deck mounting brackets on the left side, right side and front side of the mower deck. Use a socket set to remove the bolts.

3. Raise the driver's seat and disconnect the battery cable connectors from the battery with a socket. Lift the battery out of the battery compartment and place it off to the side.

4. Look down through the battery box and locate the 7/15-inch bolt that secures the transaxle pulley to the transaxle. Remove the bolt with a socket.

5. Locate the anchor bolt spring on the left side of the tractor and remove it with a spring puller. This loosens tension on the mower deck drive belt.

6. Remove the upper belt from the transaxle pulley and then slide the deck out from under the mower.

7. Remove the belt from the pulleys on the mower deck and then place the new belt onto the mower deck. Slide the mower deck back under the mower.

8. Place the belt over the transaxle pulley and then reconnect the anchor bolt spring.

9. Secure the transaxle pulley to the transaxle with the bolt and socket.

10. Place the battery back into the battery box and reconnect the wire terminals.

11. Reconnect the mower deck to the mounting brackets with the hex bolts and socket. Replace the spark plug wire.
