How do you change a drive belt on a troy bilt bronco tiller?

To change the drive belt on a Troy-Bilt Bronco tiller, first, ensure the tiller is turned off and disconnected from any power source. Remove the rear cover to access the drive belt, then carefully detach the old belt from the pulleys. Install the new belt by looping it around the pulleys in the same configuration as the old one, and reattach the rear cover securely. Finally, test the tiller to ensure the belt is functioning properly.
