I have a 4020 1965 syncro. Replaced all fluids, cleaned all screens, replaced front hydraulic pump and steering column hydraulic cylinder assembly with upgraded. No fluid leaks anywhere. While raising the 3 point it is jerky at the beginning, then raises most of the way then jerks at the top. Any ideas? thanks in advance
 
Get a John Deere technical manual. Read it like a spiritual fundamentalist reads the Bible. It's likely going to tell you to do a flow and pressure test which will require connections to specific ports on the tractor with a pressure gauge and flow test procedure.
 
Is this 3pt problem at the start of the day, after every startup, or when ever the 3pt is being used??
 
It happens all the time, whenever 3 point is being used. I do have a manual and will dig into that deeper. I assume it will tell me how to set the stand by pressure also. thanks
