Guess it depends on budget and dealer support. 4x4 versus 2wd etc etc.
I looked at a brand new MF 2607H, they make them smaller, the smallest one is basically a brand new MF 135. A real farm tractor built like the ones years ago. I'd also look at the Deere 03 series, think the 5103's are getting cheap, same deal, basic farm tractor.
Orange any smaller M series.
Red, personally I look for a CX50, 3220, 495 485 etc. Same deal, real farm tractor with some weight. Keep in mind this are all 25-35 years old now.
