Replacing the Drive Belt
The blade drive belt, tensioned by the spring-loaded
idler pulley, is very durable. However, after many

burn marks, and cracks. Replace the belt if any of
these conditions occur.

Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2.
Remove the belt covers from the top of the
cutting unit and set the covers aside.
