This is stupid, and selfish, but I had to share with someone.
I just bought a used 1969 4020 and I am THRILLED!!
It has been well used as a forestry tractor and I'll probably continue to do the same. (there is so much diamond plate and re-bar welded on that I've been thinking of it as "Frankenfourty") The engine runs great, shifts smooth, and starts easily.
I wish I could bottle the feeling I have now!
Thanks for indulging me
