My B-100 automatic is really teeing me off!
It doesn't want to keep pulling itself like it should. Acts like a belt slipping. The belt does touch itself where the idler pully pushes the belt tight.Maybe the new belt is too long,
I have a new (Toro) belt and a new tension spring on the idler.
The tow valve is also closed, and a new (hydro type) filter installed with fluid level correct.
As the tractor slows for an incline, you can push down on the "parking brake" handle and feel it pull a little better, but still not right (in my opinion).
Anyone have other suggestions?
