Troy Bilt Zero turn mower Model#17AA5ABP766 will not move
Starts... Can turn on the Blades...Belts are moving but mower will not move F or R

 

[ILENGINE]

Possibility that the bypass lever/rod has been pulled on the hydros causing the no move situation. Other than that the only other thing I can think of would be the belt came off or something, even though you said the belts were moving.
