The ground drive belt connects the engine crankshaft to the transaxle pulley to drive the rear wheels.
The drive belt is vital for moving the john deere riding mower forward. But how will you find out that your mower’s drive belt is working properly?
If the belt is worn, you will hear a squealing sound when you are driving the mower. It will move sluggishly as the belt slips on the pulley. And if it is broken, the mower won’t move.
To solve this issue, you need to replace the belt –

- Remove the mower deck – Disengage the cutting blades, disconnect the right suspension arm and right rear deck bracket. Pull out the deck from under the frame.
- Detaching the ground drive belt – Remove the engine pulley bolt and then pull the engine pulley off the crankshaft. Release the drive belt from the idler pulleys and belt guides.
- Lifting the battery: Release the bolts that connect the cables to the batteries. And put the battery out of the battery box.
- Removing the ground drive belt: Release the drive belt from the transaxle pulley and pull out the ground drive belt.
- Install the new ground drive belt: Loop the belt over the transaxle pulley, position all the bolts, connect all the cables, and install the engine pulley bolt and washer.
- Reinstall the mower deck – Push the deck near and under the tractor frame. Reconnect all the connections, right suspension arm, and deck bracket. Check the belt moving on the mower deck, and adjust everything. And then, reconnect the spark plug wire and lower the tractor hood.
Go through the manual to see how to remove the cutting deck and then the belt. You can also ask the help of an assistant to do things faster.
