The moldboard was one piece, the share that cut the furrow was the second, and the third was the landside that guided the plow. This made replacing individual parts cheaper and easier, it also was credited for having good balance and made it easy to create straight lines. This inspired further innovation to the plow.

The plows had the ability to clear themselves out so prairie soil didn't get stuck to them. Created the first steel plow but never patented his work, or produced them on a large scale.
