Whiffletrees

Also known as whippletrees. You use them with a team of horses. Ken Laundry, the owner, hasn't needed them since he bought his tractor in 1951. During the Great Depression, Ken used to cut blocks of ice from the lake and haul them to local ice houses. He used to plow his fields behind a horse. Now Ken keeps the whiffletrees hanging in his barn, just in case. Which, these days, seems like a good idea.
