    This is a 2003 model,you can hand push the 7.5' poly blade left or right. I tried a new hand controller I have with no luck, I also removed the cushion and pilot valves and they look ok. The next step is to try a couple of angle cyls from another plow to see if they will hold, any other ideas? I also checked the angle solonoid and the O-rings look good and it is operateing ok, The plow works ok, but the cyls won't hold.

    Before you go out and buy a cushion valve, I would check the "S2" (solenoid cartridge) valve to see if it is stuck, or not spooling, power to the valve ( maybe the wire is not making good contact) or a foreign material inside the channel. It is the middle valve behind the cover.

    Here is the mechanic's guide pdf

    I had the same problem, had air in the system, let the lift ram bottom out then angle back and forth a couple of times should work

    I'm with twin. Follow the trouble shooting guide in that manual. There is a passage on your exact problem.
