ABSTRACT:
A device intended to be mounted on a vehicle and used for breaking up ice and compacted snow on road surfaces or similar surfaces. A number of breaker disks are mounted side by side on a common shaft which is supported cross-wise on the vehicle. The disks are rotatable and roll in the direction of travel of the vehicle. The shaft is movable up and down and can also tilt from side to side to some extent. Yielding down pressure is applied to the shaft by a hydraulic cylinder. In one form of the device, stationary clean out fingers are mounted between the disks. The disks are spaced apart by gaps of from one to four times the thickness of the disks.
