I am hoping to find some help with advice on my F3680 steering. After mowing for about 3 hours the steering on my mower all but went out. The steering wheel turned normally, but there was no or very little movement/turning of the rear tires. After letting the mower sit for a day, the steering appears to work normally with no apparent leaks in the lines that I can see.
According to the shop manual the steering system consists of the oil strainer, hydraulic pump, flow priority valve, steering controller, and steering cylinder. In accordance with the troubleshooting guide - if the mower "can not be steered" the problem is a faulty steering controller or broken hose. What I am not sure of is what does "can not be steered" mean exactly. Does it mean the steering wheel turns but the tires do not move (my problem)? I really have no definite indication of what may be causing the problem, and at this point it appears to be an intermittent one.
I am trying to see if anyone has experienced this before that can help provide some troubleshooting suggestions that will help me define the specific problem or malfunctioning part. I do not wish to "shotgun" replace parts until the problem is fixed, especially since a new power steering controller is over $900.
