One David Peacock received a patent in 1807, and two others later.

Newbold sued Peacock for infringement and recovered damages.

Pieces of Newbold's original plough are in the museum of the New York Agricultural Society at Albany.
Another inventor of ploughs was Jethro Wood, a blacksmith of Scipio, New York, who received two patents, one in 1814 and the other in 1819.
