My zero turn had 1000 hrs and one side was significantly less powerful than the other and would not back up on an incline. I had to remove the units to drain the original oil as they were not designed for oil changes. I drained them and added Amsoil and it breathed new life into both sides after only a few minutes of driving. One side is still stronger than the other but both work significantly better and I’m hoping to get several more mowing seasons out of them now. I will be using this in all future zero turns and recommending it to my friends.
