This is the classic farm accident.Combine corn heads,corn pickers,haybines,all have fast rotating roller shafts and will eat you alive if you get close.He’s lucky he only lost an arm.

Agreed.

But as I read the story, it does not say he was sucked into the machine. It says he got stuck in it.

My guess is the machine was off, his arm got jammed in trying to get the packed stalks out. The heat from friction while running had been great enough that the stalks started to burn while he was stuck, and there was no choice but to cut his arm off, not even time to call for help on a cell phone.
