Fellows, I think you may be comparing Chevy's to those Cadillacs....a utility tractor is just that. Utilitarian. A much larger farm tractor will generally take operator ergonomics into account and have a better seat suspension, and larger tires and wheels that help smooth out the bumps a little.
And that farm tractor may spend much of its working life in huge, established fields. Not the woods, or crossing creeks, or running over logs, or clinging to the side of a hillside. With no suspension to speak of, the terrain is usually the problem, not so much the tractor.
