That Kubota must be a lemon. I can count on my fingers the number of times I have had to fix my small JD over the last 27 years, and I have used it hard. That said, I understand how the tractor works and don't do things in a way that breaks things. I also do not lend it out except when it comes with an operator (me). I don't know your brother, but do you think he might be hard on equipment? Kubota's are known for reliability, and my friends that have compact versions have been very pleased.
