What kind of cylinder are you using? If it is an MM cylinder with the lock out feature, you could have something in the top where the plunger is or a bent plunger that is not allowing it to work properly. I agree, I would look at the hydraulic coupler first.

I have swapped couplers - I have swapped hoses - The problem exists when I move the inside hydraulic lever toward the front of the tractor. When I move it back, the cylinder acts as it should - when I move it forward, it is very slow whichever way the cylinder is moving. I set the stop bolt where it is slow - if I move further forward, it pulls the engine down and does nothing. If moving the lever forward moves the cylinder out, when resting, the cylinder will slowly creep out on its own. I was hoping there might be an adjustment that I missed short of big time disassembly. On a different subject, any simple solutions to a power steering that works to the right, but not to the left?

What kind of cylinder are you using? There is a small accuating lever in the power steering valve up front (lower left under radiator corner) that could be worn. You can slightly loosen the 4 cap screws that hold the valve on, take a large slip joint pliers and try moving the valve a little and see if that helps. It works best when you have someone turning the steering wheel and checking it as you go. Just a thought on the hydraulic issue. Are the hoses on the tractor connected to the proper ports? Different ports go for single or double acting cylinders. If one lever works just fine they probably are but wouldnt hurt to check them.

Could be an internal valve issue, remove little cover and observe movements. R. and L. P.S. issues could be the "tickle" lever in the control valve.

I'm a real novice at this - what is the "tickle" lever. Is it on the hydraulic system under the seat or up front on the power steering system?
