lol, that was funny Barbara.
Beth, I started doing searches of discs and came up with "transport disc, also known as a wheel disc". I don't know what they're called around here. I've never seen one with the wheels before.
Andy, Disc harrows used to break up the ground and smooth it out, such as in the Spring, in a corn field before they plant. It gets rid of the old rows and tills in the old stalks and weeds. You need a lot of horsepower to run ground engaging equipment that big. It basically does what a rototiller does, but on a large scale.
Be back with a pic in an hour or so.
Give us this day our daily bacon.
