We have a 4wd 4025 and love it. This August will be its 3rd birthday. We have had to get the fuel line thing done, but it was under warranty and a new battery. That is it. Its powerful enough to do what we want to do. I can carry a huge round bale on the front and rear at the same time. It pulls over an 8' disk in high range. Runs a 6' shredder and 6' tiller like they are toys.
