Always a crowd-pleaser, but I think what would be an even more fair competition, would be to race a $200 scythe against a $200 mowing machine. Or better yet, determine how many calories the scytheman burned, and then give the machine an equivalent amount of calories of gasoline, and see how far it gets!
A team of 10 men with scythes versus a tractor-powered, sickle-bar mower. Each side mowed a 120 meter strip of tall grass. It looks like it was calculated to be an even match. Yes, the scythers win! By a scythe stroke. I wonder how many calories the 10 men burned, and how many oil-calories the machine burned?
