My 4710 with power reverser has 2 filters one of them is for the power steering did you change them both

I just changed the power steering filter($54). After adding fresh fluid I used the loader to lift the front end off the ground. As soon as it was off the ground the wheels went full left and I can"t move them.

(quoted from post at 10:00:26 04/18/11) As soon as it was off the ground the wheels went full left and I can"t move them.

Sounds like a PS valve problem. Is tractor still under warranty?

I just scanned through the troubleshooting section of my 4310 manual for eHydro and it does not mention that (wheels pulling to one side and staying there) as a possible problem. Maybe try turning them back with the engine off and all hydraulics bled from lever pulling and pedal pushing.

I just replaced the power steering piston(you can"t repair the original one ,welded ends) and everything is working fine. Thanks for your help
