Why buy used when you can buy new. I'm a Massey Ferguson and Kubota dealer, and your budget is well in reach. For your operation I would suggest a 500 series Massey Ferguson. Either the 573 or the 583 would fit this. This is a great line of tractors. They are simple to operate, and everything is still mechanical on these tractors compared to other brands that have electrical operation. For example the 3pt lift is as simple as pull the lever up to raise and push the lever down to lower
Some of the competitors have electrical components such as the 3pt lift. If that Ohio winter weather gets into some of those electrical components, you can be prepared to take it to the dealer. That can get costly if its out of warranty.
These 573 and 583 tractors have pre heaters /glow plugs for those winter months in Ohio as well. Best of all you will be getting one of the best engines on the market. PERKINS!!!!! I see these tractors running Perkins engines with 7 to 8000 hours on them with no problems. Plus its one of the cheapest engines to rebuild. Also, for you hay operation I would consider a shuttle shift tractor. It makes a hay operation go so much easier.
If you can't find a great deal in Ohio, let me know. If you don't mind dropping 8hp I know I can sell you a brand new 72 engine
hp 4x4 tractor with a shuttle shift transmission, dual hydraulic outlets and canopy top for less than you budget. Best of all a FULL WARRANTY.
