Does any one have a good pic of the belt routing? I seem to have mine correct from all the pic's I can find. It wooks fine in the down position, but when you lift the machine up to transport it pulls the belt tight and ingauges the machine. Was this just how they worked?
Todd, I Think I have the same unit you do.
Thanks,
Jason

The loop in the belt comes forward a ways when on the tractor, right above the pivot point. Thinking about it, how would it engage unless the pedal operated PTO was engaging?

I have the same 620, and it looks like I have my belt the same. Does you belt get tight as you raise the machine, and then the machine is running?

I don't have a blower on a tractor now but I do remember that when the blower is raised and lowered it did move in an ark, that would move it a little closer and further away for the tractor but not all that much.
When my clutch was released (belt loose not turning) I noticed that there was a lot of slack in it, and when clutch engaged (belt tight and turning) it worked fine.
Maybe try to loosen the belt off a bit, there is a lot of adjustment in those.
If you look at my 3rd pic you can see the belt is tight. (clutch engaged)
The 4th pic the belt is loose (not engaged) you can see how much slack the is, need too zoom in to see this.
The pic posted by "mikebramel" shows the same thing.
