Yeah, a rotary or forestry mulcher makes a lot more sense for what you're trying to do.
I agree, i wouldnt try to do what he is talking about with a chipper.
pay somebody to clean it up once with a mulch head, you can hit with a mower after that.
I bought a 3in chipper for around the yard, if you go that route, definitely by something twice the size for what you are planning to chip/shred. My 3in barely did 2in stuff well, and it was insanely loud.
