In that size tractor, there are very few bad tractors. I'd just stay away from the Chinese tractors and European tractors. The Chinese tractors, because of quality and parts availability, and the European tractors mainly because of parts availability.
The tractors made in Japan, South Korea, and India (i.e, Mahindra) are all excellent these days. That will cover most of the tractors below about 50 hp, and actually it will cover most up to 60 hp. Except for maybe John Deere, most of the utility tractors are primarily from overseas companies -- but many of them are assembled in this country.
Maybe our friend Todd L., will pop in. He just went through a long search for a new 40 hp 4WD tractor with front-end loader, and bought a Mahindra. But, he looked a lot of tractors and brands over the last year or so. I've had a Mahindra for five years and it has been great. I never even got to use the warranty.
