Ok here we go. let me start at the end I have replaced filter and fluid and checked level. I have replace the orfice in the safety valve. check for worn parts. and have not fix the problem which is when all three control levers and in the center position you can here the hydro pump build pressuer and the engine lose rpms when I move the vales off center the rpm's go up and the hydro pump sound nornal. What is wrong?

I have temporay used a jumper hose between two ports and bungy one of the levers open. this relives the pressuer on the pump and the engine run at normal rpm. but I dont want to leave it like this


Thanks for your help

Thanks

Definetly something's still not quite right in your saftey/regulator valve. What did the pistons and their bores look like? Dosen't hurt to clean them up with fine emery cloth. Might not be a bad idea to take the valve off of the tractor and totally disassemble and clean it. Might be some junk in the passage below the screen.

I would run off a copy of that troubleshooting procedure posted by MN Scott. Any 460 owner should also run off a copy in case they ever have problems. It was very well written and informative. Hal
