What if the pto is always spinning with the handle off ,, then when you throw it up to work it does fine . It’s not to bad but is aggravating when you have to turn tractor off took hook up . It’s on a 1971 4020 power shift . Enjoy your channel!
It was done right before I bought it, so I don't have the part numbers.... But I think all that can be sourced through the deere dealer as an upgrade. also, there's a guy on Yesterday's tractors.com by the name of Tim S. He'd be the guy who could get you the right part numbers for that. He posts in the JD forum.
