I was fortunate enough to run across a person who gave me a Ford 3910 about 10 years ago. It’s a 2wd and no FEL. It came off of a sod farm with over 10,000 hours on it. I haven’t had to do anything with the motor as it keeps going. It’s only 47 horsepower and probably about 43 at the pto. It’s all I need until I’m gone. I’m just a causal user now just using it 6-8 days a year. Hopefully you can find something. I’m always looking and I can pass along information if I come by a 4000 series. They are solid tractors.
