I just bought a used Troy-Bilt Super Bronco 46" Riding Mower...I believe it's a 2009. I used it for about a 1/2 hour and then the PTO (blade engage lever) stopped working. When I swing it up the blades do not engage and the lever seems much easier to operate. I originally suspected it was the PTO cable that connects the lever to the plate on the blade deck. I thought it might have stretched out (because there was way too much slack) but now I'm thinking that when the previous owner had the belts changed the pulleys weren't properly re-adjusted. I have no experience with these mowers. Any ideas as to what the problem could be? Here is a diagram of the PTO lever [URL="http://partstream.arinet.com/Image?arik=xlOoLenQ3FIMfutcqZzT&arib=TRB&arim=iHgosf8xs9iGaD0Y6BPEmA2&aria=urg6BG9WkgNUuIGNQIX0Pw2&ariz=2&ariv=http%3A%2F%2Fwww.thetroybiltpartstore.com%2F%3Fgclid%3DCMztv8zTpr4CFbIDOgodnj8AcA"]http://partstream.arinet.com/Image?arik=xlOoLenQ3FIMfutcqZzT&arib=TRB&arim=iHgosf8xs9iGaD0Y6BPEmA2&aria=urg6BG9WkgNUuIGNQIX0Pw2&ariz=2&ariv=http%3A%2F%2Fwww.thetroybiltpartstore.com%2F%3Fgclid%3DCMztv8zTpr4CFbIDOgodnj8AcA[/URL] Here is the 46" Mower Deck [URL="http://partstream.arinet.com/Image?arik=xlOoLenQ3FIMfutcqZzT&arib=TRB&arim=iHgosf8xs9iGaD0Y6BPEmA2&aria=VRPVW-4ZcO8__vPjMJnKyA2&ariz=1&ariv=http%3A%2F%2Fwww.thetroybiltpartstore.com%2F%3Fgclid%3DCMztv8zTpr4CFbIDOgodnj8AcA"]http://partstream.arinet.com/Image?arik=xlOoLenQ3FIMfutcqZzT&arib=TRB&arim=iHgosf8xs9iGaD0Y6BPEmA2&aria=VRPVW-4ZcO8__vPjMJnKyA2&ariz=1&ariv=http%3A%2F%2Fwww.thetroybiltpartstore.com%2F%3Fgclid%3DCMztv8zTpr4CFbIDOgodnj8AcA[/URL] Any tips, clues, advice etc. would be much appreciated.

Model 20031 bought in '04. No problems until now. Mower barely moves forward and can't be pulled backwards. Can hear either an intermittent grinding noise or belt slipping noise. Was working fine 4 days ago. Any help would be appreciated.
