To all members who haven't grown grown up around corn-pickers or combines: NEVER, EVER grab a corn stalk that is wiggling around in the snapping rolls while the machine is running or idling. You may think you can tug on that stalk and pull it out, THEN in an instant those snapping rolls grab it and down it goes and your arm goes right in there,too! If I remember correctly reading the owners manual on Dad's old cornpicker, I believe the snapping rolls take a 1000 ft per minute. That is 16.6 feet per second, even if your reaction time (to release your grip) was .300 seconds(fast), those snapping rolls already took 5 feet of stalk or your arm into it. Please be safe.
