Norm, I don't think I explained it quite correctly. So what is happening is that the belt comes off the idler pully on the left hand side and it hits what they call I think the clutch pully. What is happening is that the belt will flip on its side on the left hand clutch pulley. So the belt will run on the side of the v over the left pulley instead of sitting in the belt in its v formation. When you put a brand new drive belt on and tension it up, you can start the mower and let it run at idel and the belt does not run on its side and runs normal. But as soon as you up the revs the belt will slip/flip back over onto its side on the left hand clutch pulley and continue in this manner all future rotations. unless you re tension and flip it back. It was doing my head in so I paid a very experienced mobile mower mechanic too look at it. He said he has never seen a greenfield do that before in 30 years. He didn't have time to change the clutch pulleys there and then but that was his suggestion for rectification.
Talking to an ex greenfield dealer he suggested I try and obtain an A134 Super 2 raw edge belt as a first shot before replacing the clutch pulley. However I did the ring around to about 10 belt places and no one could get one. So the project for the weekend is to replace the left hand clutch pulley and the idler pulley and hope and pray that fixes.
Bruce: in answer to your question its a 34 inch greenfield fast cut with the briggs and Stratton 27hp in it. I think its like 2017/2018 vintage.
