Abstract
A detachable or separable scraper bar attachment for various types of trad vehicles includes first, second, and third generally planar rectangular bar elements which when fixedly interconnected and attached to a vehicle's body frame form a generally U-shape or .mu.-shape configuration, of which the first and third bar elements constitute generally parallel legs of the u-shape or .mu.-shape portion. It is mounted with the legs generally also parallel to the vehicle's cylindrical drive sprocket hub subassembly. One leg is in close proximity to the hub to facilitate the scraping of collected mud or debris, and the other leg is adapted to be operatively rigidly attached to the vehicle frame; and the second bar element which constitutes a bight portion connecting the legs of the u-shape or .mu.-shape portion is notably canted at an angle of between about 45.degree. and 60.degree. to laterally deflect the scraped-off mud or debris away from the track paths. The separable mounting of the second and third bar elements is necessary to facilitate mounting, demounting and related maintenance involving the drive sprocket hub assembly.
