Do any of you own a DR wood chipper? Is so, I would like to hear your thoughts about it. I am looking at a model that has 13hp and says it can chip branches up to 4.5 inches thick. I need it to clear out invasive Chinese privet (some of them are that big). I had a smaller chipper before, but it was underpowered and was a cheapo brand. The price of the DR is about $2300. For that price, I really need it to work.
