[ What is claimed is:] [1.] A scarifier machine for removing soil comprising:a self-propelled frame;at least one milling drum mounted for rotation about an axis, including active elements secured to the drum for contacting the soil to be removed;a protective sump reciprocally connected to the frame for supporting the drum on the axis for motion on a curved path laterally and transversely of said axis;a first motor connected to the milling drum for rotatably driving the drum about the axis;a second motor:shaking means operatively connected to the second motor and mechanically connecting the sump to the frame for reciprocating the sump, including a shaft having a longitudinal axis, a first support having proximal and distal ends, and being secured at the proximal end to the frame;an eccentric mounted on and rotatably secured in the distal end of the first support for reciprocating the shaft relative to its longitudinal axis; anda second support having proximal and distal ends, the proximal end secured to the sump and the distal end coupled to the shaft for carrying the sump and milling drum together for synchronous relative motion.
