Husqvarna YTA19K42 hydrostatic transmission noise

SOURCE: Husqvarna, GTH2454T Hydrostatic power loss.

If it's like mine the transmission is sealed and cannot be serviced. A local repair shop told me most likely the problem isn't with the transmission but rather the engine pulley is worn. He said if sand or debris gets between the belt and the pulley which has a definite "V" shape to it that it will wear down to a "U" shape. Now mine has a foot clutch on the left side so he had me pull back on the pedal which manually tightens the belt. I did this and it works like a champ. This winter I'll change the pulley.

Don't ever crank it again. They forget to connect something at the factory. Do any more, and they'll fight you not to fix it. Now, call them and make them fix it.
