I spent many days as a kid, following mules and horses behind the old walking plow. The Vulcan #12 was a wicked piece. But, the Chattanooga # 95 was a wonderful tool. That one was left handed, with slatted moldboard. It was lighter, and ran true enough for a very small boy (me), to plow all day, in the KY creek bottoms. And, don't let anyone fool you. Those old plows could really turn the sod or stalk ground completely over, and do it 6 to 10 inches deep, when properly set up. But a lot of folks, just "cut and covered", as dad called it. By the way, I see some folks doing that with the small tractors too.
I will be watching for one of those to "adapt" to the Yella' Mule.
