Love the unit but think that there should be some kind of tension pulley system on the belts that power to chipper drum. Also, should include a couple extra replacement belts. It’s very easy to over feed hard wood especially larger pieces and stall out the chipper drum. Once the user is familiar with its limitations, on feed speed, the feed rate will become less problematic. The 15hp motor double pulley will slip on the belts resulting in burning the belts. I shut it down fairly quickly after sticking the chipper, but did burn some of the belt rubber.
