Another, more discreet, name for LSD that comes on a blotter/tab.
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.
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. http://www.bcsshop.com/index.htm. I thought the current gravely's were being built in WI also, which is why that china ad surprised me.
