I looking to buy a used tractor to help out on our small farm. This will be my first tractor. I would like to keep the price around $12k. I want 4wd, a loader and between 40 and 50 hp. The tractor will be used to bushhog, till gardern, grade driveways, move round bales and possibly square bale some hay. I would like a Kubota but would entertain other models as well, just do not know which models to look for and which to stay away from. The age of tractor is not a big deal but do want something that will last me awhile. Any advice will be appreciated.
