Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
you say engine turns in wrong direction? Is the drive for blade correct? I doubt the engine is turning in opposite direction, could the linkage to the hydrostat have gotten flipped over, so reverse and forward are reversed?
the hydrostat is directional. It will work in either direction.
I see question is still open.??
Is transmission full of oil? If tires are of ground, do you get any movement.? Is the input shaft being turned by engine?
Drive belt turning transmission input shaft?
Is the transmission turning the same direction as it was before? If not, can belt be twisted to turn shaft same direction as before.
I don't find a breakdown of the hydrostat transmission . It may have internal pump that can be flipped to change input direction. Do you have parts diagram for transmission ? The 1659 manual I found only shows a manual transmission.
Do you have any numbers off the transmission? Make and model?
