Title from the CBS story - http://minnesota.cbslocal.com/2018/05/16/richfield-man-dead-landscaping-accident/
This is from a thread on Reddit. I don't know his exact relation to this story. He also linked to this picture.
"Chipper got clogged, happens from time to time. Newbie loading, wiry oak both probable led to the jam.
There are ways to clear the jam safely, though they can be a chore.
There is a heavy metal shield that completely covers the anvil. For those that dont know, they anvil is a 3 inch thick, 3 foot diameter solid steel wheel that the blades mount to. This big ass heavy steel wheel is no joke, hence the heavy duty cover.
You can open the cover to remove debris, but removing the cover unplugs a safety switch that will prevent the machine from running. Of course, a guy could jump the switch, or use an old plug off another machine, or use some other basic way to defeat this safety feature. Doing so however, will allow the machine to spin the anvil, which doesnt **** around, with no protective cover. Bold move Cotton.
This pic is from yesterday. You can see half of the anvil exposed, due to the cover being gone. This is unusual because the cover is hinged (you can see the hinge pipe on the top of the remaining cover section).
Long story short: faster way to clear a jam is to remove cover and start the machine. Anvil/blades started spinning and hit the movable half of the anvil cover and sent it flying, into guys head. Now he is dead."
