Maitland is a farming community. One of the farmers from Maitland was David Ward King, inventor and promoter of the King road drag—an invention that essentially was two logs lashed together and dragged behind horse or mule teams that was an effective and inexpensive method to grade dirt roads. It was the horse-drawn forerunner of the modern road grader. The invention came at the time Henry Ford started to mass-produce automobiles. Before its invention, wet country roads became muck and were often nearly impassable. The use of the King Road Drag kept rural roads solid, even when wet, which rendered them passable all the time. These improved rural roads made possible both the advent of the automobile and rural mail delivery.
