I have what is probably a simple question about the PTO on my 1320. First a brief background, I just bought the tractor last fall (2007) from a guy that was only using the tractor, the deck was laying behind his garage collecting rust. I decided to get the mower running this spring so I replaced the blades, idler pulleys on the deck and PTO and some miscellaneouse springs, bushings, bolts etc. Mounted the deck up and it appeared the PTO was functioning OK, the belt tightened and the pulley brake released when the lever was pushed forward and of course the opposite when pulled back. When I started the mower up, the blades started spinning right along with it even though the PTO was in the off position. This of course got the pulley brake and belt to smoking. The belt is the correct part number and size and is loose when the PTO is off.
My question is, is there supposed to be some kind of clutch on the pulley coming off the engine crankshaft? Or is the belt supposed to be pushed completely off of that pulley when the PTO is not engaged? I don't understand how the blades are not going to spin when the engine is running if this is not the case.
