        Is he reservoir full?  The power steering reservoir is a lot smaller than the main hydraulic sump and it doesn't take much of a leak to drop it down to where it won't work well.  The other thing that could cause that issue is if the seals in the steering cylinder are leaking/bypassing – since it is a double-acting cylinder, leakage past the seals would cause pressure to build on both sides, neutralizing the power.  The rebuild kit is cheap.

          Hi Rich. Yes the reservoir is full, I check it often because of the one leaking fitting. When it's low the steering wheel turns but not the wheels, so the blown seal makes sense.

            Well this is interesting. We got dumped on big time last night, 26″ in 12 hours. After digging my way to the tractor and dealing with an uncooperative starter the steering worked just fine. It's like it needed it to be 17 out to work. Any thoughts?hmmm I'm not complaining mind you, I used the loader to clear 200' of driveway so I could move a car, a trailer and a truck. In the morning I'll search for the back blade that angles and finish my driveway and do the neighbors.

              Sounds like the cylinder seals are bypassing when the fluid is warm enough to thin out some, but not bypassing so much when cold and thick.  I suppose you could test this easily enough by draining and refilling with much heavier hydraulic fluid.  Or just spend the $25 and put new seals in the cylinder and a new bonded washer and be done with it.
