Hi Pete. That sure is going to be a nice 4020 when its done. My father and I got a 4020 from a guy and he bought it from france. It looks identical to yours with the lift asist three point hitch. I was just wondering if you know the serial number, it would be nice to compare it to ours and see if the numbers are close. I attached a picture but dont have one of the rear end to show you the resemblance. thanks and good luck with your restorations.
