good basic work tractors.. good parts support depending on t he model, some very good.. pretty easy to work on. I consider them the average mans tractor.. etc.
if you are gonna get one to play with in the 35-45hp range I have 2 suggestions.. a gasser 55-62 860/861 preferably with factory power steering (or 63/64 4000 with dual clutch and ps).. or a newer 3 cyl 3000 diesel , power steering, 8spd dual stick tranny with dual clutch. if you need a larger machine.. then a 4000/4600/5000 would be quite a bit of tractor..
