I have a Kubota 2050, 25 engine hp and 20 pto hp, I recently purchased a home on 4 acres that had a huge brush pile in the middle of the property. I spent the summer trying to figure out what to do with it. It was approx 40 foot square and 10 ft high. So I did research on pto driven chippers and finally purchased an Oxxn chipper a little over a month ago. I have a fireplace so I cut up any fireplace worthy wood and ran the rest of it through my new oxxn chipper. I have about one day of work left and the whole pile will be gone. That chipper is really amazing, and my tractor has no problem running it. I purchased the hydraulic feed version and it works great. I would buy it again and would recommend it to anyone needing a good chipper. From what I can tell most replacement parts can be purchased at the farm store or auto supply. The people at oxxn are very helpful too. Hope this helps. Just MHO.
