Gravely Lawn Tractor History. 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.
Gravely built its reputation largley on the 2 wheel walk behind tractors, but the riders use many of the same attachments (though they do need a special front implement mount kit on the riders). Both the two-wheelers and tractors are built to last.
