What I think I know about Ventrac is more than I really know. With that said they are really good machines but very expensive to repair. You have 1 real option and that is have dealer fix it. I have not heard much on them breaking. But that may be because most can not fix them themselves. Now with that said if i could get one that was designed for hill mowing i would buy it and put it to work making me money right away. Hill mowing is needed in my neck of the woods. I could get a $60,000 contract from the city right now if i had such a thing. Problem is money to start. Do not have any. Back to your question. No idea what resale is but im sure it is high as supply is low and demand it high. I would try to find retail cost and if it is 1/2 or less of the price I would buy it.
