14AT809H766 with the vari-drive system. *see attachment
I recently changed both drive belts with MTD p#'s and the mower drove as it should for about 5 minutes (I was so happy LoL) then the pedal went to the floor and the mower stopped moving again.
I checked all pulleys/ "throttle" linkage/...
I recently acquired a new (to me) Troy Bilt 14AT809H766 with the Briggs & Stratton 752B0344E1 21HP engine.
I has right under 300 hours on it. I just installed all new filters and changed the oil.
Anyways, about 3/4 into cutting our 2 acres I could smell burnt rubber and a bit of black smoke...
