I have come to the decision that if I want wood chips, it makes sense for me to utilize whatever an arborist will drop by rather than creating them myself. The equipment, the time, the cost, and the feedstock are all significant issues for me to deal with compared to spending the time developing relationships with the folks who already have all of that.
I have a little
homeowner chipper and use it for dealing with brush but I can't imagine getting one of those large chuck and duck chippers and keeping it maintained to only use it a couple times a year. Perhaps if I had more forested property and time on my hands it would be a different story.
