Gravely lawn tractors sorted by year. The Gravely Motor Plow Company was founded in 1916 in Dunbar, West Virginia building a successful line of two-wheel walking tractors. The company later moved to Charleston, North Carolina and, in 1964, Gravely entered the four-wheel garden tractor market. Gravelys used a unique rear-engine design on their tractors. Ariens purchased Gravely in 1982, and still owns the brand.
The first lawn mower was invented by Edwin Budding in 1830 in Thrupp, just outside Stroud, in Gloucestershire, England. Budding's mower was designed primarily to cut the grass on sports grounds and extensive gardens, as a superior alternative to the scythe, and was granted a British patent on August 31, 1830.
