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.
Dull Mowers. Turf may have a gray to brown cast following mowing. In most cases this discoloration can be attributed to dull rotary mowers, although reel-type mowers may cause the same kind of damage. Basically, the discoloration is due to tearing, splitting, or shredding of the tips of the grass blades.
