With the price of Kubota parts, you are going to go broke if you need to purchase all the parts new. I would be looking for a BX1800 or BX2200 tractor that is being parted out, and purchase everything from that tractor to install on your tractor. The best part is if you can remove the parts yourself, because that way, you will know exactly where and how everything goes back together, and you will have every nut, bolt, washer, etc.. You might even want to look for a machine locally that has everything that you want, at a reasonable price.
