Hello all,
The three point hitch on my Deere is pulsing when there is weight on the arms and it is not in the full down position. It typically happens about 2 Hz when the ROD valve in a normal position. Much slower (1/4 Hz) when the ROD is fully closed. I've replaced the seals on the ROD valve, cylinder cover, cylinder and rockshaft control valve (external to the RCV, not internal). I've also installed a new cylinder relief valve. There has been no change in behavior. There are no external hydraulic leaks. It seems like the RCV is the only point left in the system that hasn't been changed. Would this typically be the culprit for this type of behavior?
This isn't an antique tractor, but this forum was recommended for the experience of its users in tractor repair.
Thanks for any help you can provide.
