As someone who spent many, many years iperating wood chippers all day, I can comfortably say:

1. They shouldn't have been using a drum chipper. For a body, you want a nice disc chipper, mainly because of where the ejector is located and how well the debris can be directed.

2. It's clearly a homeowner model. No horsepower at all. Dude is basically just juicing Carl by the time Marge finds him.

3. You have a whole fucking lake there and you're chipping into the snow on the shore? It looks like someone set a pie on a fucking landmine, Gaear.

4. You need a big pile of brush to help the parts run into the chipper and then after each body part, I'd suggest running a couple of nice clint piles, preferably of something bushy like fir or pine, through by itself. You want to clear the chipper knives/disc and the clean brush is also going to lay down some nice green cover over the hige juicy mess you're making.
