My personal experience with Kubota motors has been all great. I have owned two 1990's B20 backhoes. One I bought was from a rental place. You know that must have seen some abuse and still ran great everyday untill i sold it. I currently own two B26 backhoes and motors have performed flawlessly. Also own one Kx121-3 also a great motor. I think they are bullet proof. You can't kill them.
