I'm on an email list that posts new homemade tools daily. Usually homemade hand tools, belt sanders, drill presses, sheet metal benders, etc. But today this pic captioned "tractor cow rotator" came across with no explanation, and it appears to be a tractor mounted device for rotating a cow. Couldn't google up an explanation and couldn't think of any reason you would rotate a cow.
Anybody have a reason for this device's existence?
