Abstract
Abstract A digging bucket adapted for side dumping in one or two directions is open at one or both lateral ends. At said one or both open ends the bucket has an extension member which cooperates with the bottom of the bucket and which during side dumping is movable from a retracted position to an active position in which it forms a laterally outwardly projecting extension of the bucket bottom so as to deposit the excavated material at a distance from the excavating vehicle.
