Used my 4320 yesterday the 3 point is very slow to react, and then will drop down on while turning for my return pass moldboard plowing.

Sounds as if hyd system has an internal leak, my guess leak is rockshaft piston seal or RS control vales leaking. How many hrs of use since hyd filter was changed & hyd oil suction screen cleaned? I suggest to acquire a 5000 psi gauge & check hyd stand-by pressure.

Not sure what has been done on the tractor. Other than upgrading the batteries and installing something that helps it start better. Needed the Deere item.

I spent the last year cleaning all of the dirt and oil from off. Just baby powdered the tractor to find oil leaks.

Going to be splitting to replace the clutch and fly wheel. This fall when time permits. Internal transmission seal is leaking.

Hyd pto control valve on this model has a long history of causing hyd problems
