Troy Bilt Horse won't go in forward or reverse

[austinferris]

My 2010 Troy Bilt Horse Model No. 13WX79KT211 will not go into forward or reverse. It has a hydrostatic transmission. The belts seem to be intact. I was making a sharp turn when all of a sudden the tractor wouldn't go forward anymore at all. I thought maybe the transmission bypass rod had become disengaged and that rod seems loose and like it doesn't work at all. Please let me know if you have any ideas.

Belt might just off one of the idler pulleys. I had a neighbor that his kept coming off until I installed a new belt. He just be going across his yard and the belt would jump off especially if he had to brake quickly.
