How to Tighten a Tiller Belt

Place the front of the tiller against a wall to act as a support to the tiller and to keep the tiller from lurching forward during the testing phase.

Place the tiller into neutral and then power the tiller on. Allow the tiller to idle while you work on the clutch.

Position yourself in front of the belt guard on the right side of the mower and inspect the belt for movement. If the belt moves while the tiller is in neutral, it indicates an improperly adjusted clutch.

Locate the clutch cable extending from the clutch lever. The cable runs though a metal bracket. On the bottom end of the bracket you will see a Hex-shaped sleeve. On the top of the bracket, you will see a hex-nut.

Turn the hex-shaped sleeve two full rotations away from the mounting bracket with a wrench and then turn the hex-nut until it rests tight against the top of the bracket.

Pull in on the clutch handle, place the tiller in "forward" and then slowly start to release the clutch. With the clutch lever released approximately ¼ of the way, the tines on the tiller should start to move. If they do not move, back the hex-nut away from the bracket two turns and try again.
