Thank you all for all the info. Last October my neighbor was cought in a PTO shaft that was driving a grain auger. Thank God two helpers were around the corner, heard the scream followed by the tractor loading down. He was air lifted to shock-trama in Baltimore. It was touch and go there for a while, he almost lost use of an eye. Many operations later he's back to getting around. Scars will last a long time.
Again it was just the harvest time, hurry up and get it done, shaft guards were not in place - no time for that now - we have corn to combine. Ask him how he feels about it now! I still worry about the Highschool kids he hires to help at harvest time.
I'm a volunteer leader for our 4H club and you keep stressing safety, but it dosen't hit home till it's too late and someone you know is injured or killed.
John - thanks for the resources on tractor safety. Our 4H group WILL be going over it next Tuesday (again).
