Cooter was the mechanic in the fictional Hazzard County, in Georgia. He owned The Hazzard County Garage in Hazzard County Square, directly across from the Police Department and the County Bank. Sometimes called "Crazy Cooter" (his CB handle), he was a wild and scruffy-looking man, usually seen in sleeveless shirt, filthy blue jeans, and a well-worn ball cap. He maintained a steady business, mainly because the Duke boys were constantly damaging their car, The General Lee and ultimately eventuating the wreckage of the county patrol cars as well (as Cooter once pointed out, following the Dukes around is guaranteed to increase his business). Everything from a new door or bumper to a simple wash and wax cost $35.42. Cooter drove a variety of trucks. In the first season, he drove a brown 1969 Chevy C-10 tow truck; in the second season he drove a blue and white 1967 Ford F-350 Custom tow truck, and he also had a blue 1968 Chevy pickup; in the third season and half of the fourth season, he drove a yellow 1979 Ford F-350 Custom tow truck; in the half of the fourth season and rest of the series, he drove a blue and white 1968-72 GMC C-Series tow truck.
Cooter was also an "honorary Duke", as he was the best friend of the family and he regularly assisted them in foiling Boss Hogg and Sheriff Rosco P. Coltrane. During the episode, "Happy Birthday General Lee", it is explained that Cooter actually helped in restoring The General Lee from a wrecked black 1969 Dodge Charger. He was also the supplier of its unique orange paint (it was all that he had, in a quantity sufficient enough to paint a car with). It is also suggested that it was he who supplied the famous "Dixie" horn. Though Cooter also owns a small farm, it's apparent that it isn't used for farming. It has also been implied that Cooter often lives out of his truck. Though Cooter wouldn't start a fight without good reason, he does enjoy a good fight (being quite a good fighter, himself, Cooter rarely loses a fair fight).
During the 1979-1980 season, Ben Jones boycotted the show due to a dispute with the producers: Jones felt the character should have a beard and the producers insisted that he be clean-shaven. As a result, Jones left the show for several episodes and it was explained in the series that Cooter was out of town. Filling in for Cooter at the garage during his absence were his cousins, B.B. Davenport (in only one appearance, played by Mickey Jones), and L.B. Davenport (played by Ernie W. Brown). Ben Jones eventually gave in and returned to the show with the episode "Treasure of Hazzard", (1980).
