David Ward King (October 27, 1857 – February 9, 1920) was an American farmer and inventor of the King road drag. His invention, which was the horse-drawn forerunner of the modern road grader, had a great influence on American life because his invention improved the widespread dirt roads of his day to the extent that they could accommodate the advent of the automobile, rural mail delivery and mail order catalogues.
