I'm looking for a new (or used, really) wood chipper that can take 5" or more with a tow behind hitch. Not a PTO, but a stand alone gas model. Anyone have one they're overjoyed with and can recommend? I bought the DR Power leaf vac and chipper combo for $2200 bucks and was so disappointed with the chipping (pathetic) and the leaf suction (dismal) that I sent it back.
