After putting a few more hours on my
chipper over the weekend I can say now that it does perform very well now that I know what it likes. I did tension the springs a bit but not much. I spent some time before hand with my saw cleaning up some of the limbs to accommodate the
chipper and things went much smoother. Now I know when Im limbing to be more selective of how I cut the limbs up. I do still wish I would have gotten the 6" model though, even the largest oak limbs went through this
chipper with no problems and the tractor never bogged at all.
