A continuous excavating and loading machine having a front mounted rotary digging element divided into sections to allow cantilevered support, digs a width greater than that of any other part of the machine so that the machine may advance on the surface it has cut. The digging element is driven by digging chains which also break up material in their path so that the full digging face is excavated. Excavated material is discharged outwardly from the digging element by both centrifugal force and gravity after rotation past top center. The excavated material falls onto a conveyor system to be elevated and transported to the rear of the machine for transfer to appropriate carriers. A moldboard blade trims surface irregularities and pushes passed material forward into the bucket wheel. A movable skid plate, held against the cut surface by a constant force, supports digging torque reaction loads and damping is provided for shock conditions.
