We had all kinds of relatively small, older tractors on the farm. Ford 9n, 900, IH A, H, 240, JD H, 420U, 2020, 2010, 1530, Case 530. Later JD5500N, and Massey 275. Had a nice IH1066 for a while, but it was too big for what the 1530 had been doing. It was replaced by the MF275. My dad had a caterpillar 22 with a homemade blade when I was young, but I only ran it a little. (no electric starter) Hand cranked the IH a and H's a lot, and the JD H a couple times.
Been skidding logs lately with the last IH H. It is a 1948. It goes in the 4th of July parade, and has been on 5 Great Iowa Tractor Rides. 2009-2017. I bought that one because H's are low maintenance, nearly anyone can learn to drive it in 5 min or less, fairly light, durable, and best of all, they are cheap and plentiful for the time being. It runs over small trees pretty easy. No live PTO, Live Hydraulics, and n 3pt. hitch. Great for pulling trailers/implements/logs and joy rides.
