I have a Toro 22" Recycler Model 20331 walk behind self-propelled lawn mower. A few weeks ago the front wheels stopped turning when the lever was engaged. I checked the belt while holding the lever down and it seemed awfully loose so I guessed it had stretched too much. I couldn't find a belt locally so I had to order one off Amazon.
Yesterday I installed the new belt and tested it. Holding the lever down engages the front wheel transmission and the wheels spin, but this only works for a few seconds. It doesn't matter if the wheels are on the ground or tipped up in the air. Is there an additional adjustment I must fix?
