Lived in the country my whole life. Never have done that one.

Thank goodness for modern tractors. I have had to start different tractors from the ground that over the years(my old 4020 especially), it pays to double check everything before and to do nothing in a hurry. It seems like tractors that are hard to start will start on the first spin when they are in gear.
I hurt my back several years ago. It will be fine for months at a time and then "pop". I have had it take me from standing up down to my knees. It is terrible when a grown man has crawl back to the house because he can't find anything to get ahold of to pull himself up to walk.

It wouldn't be so bad if the wife didn't think it was funny.
If you haven't every hurt your back, be thankful and be careful.
