Abstract
An end bit for selective and adjustable mounting to an earthmoving vehicle structure, such as a bulldozer blade, having opposite corner portions. The bit includes transversely extending cutting edge portions and a mounting portion adapted to be selectively mounted to either of the opposite corners of the blade with one or the other of the cutting edges exposed in cutting position and with the nonexposed cutting edge disposed in a retracted position. The mounting portion is further adapted to permit the bit to be selectively repositioned on either blade corner portion in any one of a plurality of different extended positions to compensate for wear of the exposed cutting edge.
