We have several tractors (a hobby now held over from traditional farming) and tend to get the most reliable use out of our 50/60's era gasoline Deere tractors. The most trouble comes from the diesel machines with higher hours(what is typically seen as affordable), in fact every one of our diesel tractors is layed up right now. The bobcat is temperamental on its best days. However, the most useful machine on our property is our kawasaki mule, used every day and is a plain and simple labor multiplier. This is what I suggest most people start with unless they need a PTO for other tasks. By the most well maintained machine that is suitable for your needs or put the money down for a new Kubota.
