No kidding, I didn't even get time to ask the question before being sent into the system!!
Last fall the Hydro-drive Quit on a very hot day.
The engine conttinued to run, but the drive smoked, and froze up.
The mower will move if I open the release valve, so I can push it around, but it will not move under power.
I bought the mower second hand with all original documentation, but first want to know if the thing is even repairable. It was working, but the problem appears to be in the hydro drive.
I was going to start with a flush and refil of the fluid, as I suspect this was never done by the original owner.
I do have his service records and they only mention tune-ups at the service center where he bought it, no drive service. He did get new belts and blades on the mower at one point.
I know this thig is pushing 30 years old but also have herad how tough these old CI drives are. Will a flush do any good or is it something worse?
