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.
Those rapid units look pretty Good. They look like they would be user friendly and take a lot less effort to move around than a 5000 series Gravely. I also found This company for a 2 wheel in Mass. I thought the current gravely's were being built in WI also, which is why that china ad surprised me.
