    4120 Steering Intermittently Won't Turn Left

    The steering on my 4120 works fine 90-95% of the time. The other 5-10% of the time, the steering won't turn left. The steering wheel will turns forever without stop. At anytime, I can turn right, and it works fine. This happens with the engine hot or cold, moving or at a standstill, a brushcutter on or off the 3 point hitch, and with a load in the FEL, or an empty FEL. It is a hydrostatic transmission model, and the hydrostatic/transmission fluid level is correct, and have not noticed any leaks.
    I have clipped a few doorways, because of the loss of steering and it is starting to make me angry. Does anybody have a clue as to what it can be? Thanks.

    It could be either the orbital steering valve or the cylinder, unfortunately your probably going to have to wait till it happens more frequently to narrow it down.
