I show you how to easily change the deck belt on your Troy-Bilt Bronco riding mower without removing the deck. This is the belt that controls the blades. The belt on this mower had been installed incorrectly so I didn’t have to initially loosen the idler pullies–but if your belt is intact you probably will to get the old belt off. This is the same process for most riding mowers.
