I would look for a Kubota BX series tractor with either a 54" or 60" mower deck. I bought mine 5 years ago, and it has been a great machine. Mine is a BX22, which has a mid mount mower, front loader, and a small backhoe. It was expensive, but I will have it for the rest of my life. You can find cheaper machines, but they won't last as long. If you can't afford new, look for a used machine. They are just about bullet proof, and the Kubota 3 cylinder engine is good for about 10,000 hours with just oil changes. There are some good deals on used ones, when people upgrade because they want something newer or larger. I would stay away from the BX1500, since it is a 2 cylinder engine that vibrates a lot.
