Abstract
In order to improve the efficiency and reliability of the cutter units employed in large scale ice disaggregation systems, a cutter configuration is employed characterized by an outwardly extending arm which sweeps rearwardly from the direction of travel to provide clearance for ice chunks and then sharpwardly forwardly to terminate in an ice-engaging portion. The ice-engaging portion includes a relatively long and narrow central 'pick' portion for breaking very cold ice, chisel-like cutting edges directed to each side of the base of the 'pick' portion to fracture cold ice as well as warm ice, and an inverted skate portion which cleaves the ice and promotes passage of the ice chunks around the tooth structure to facilitate clearing.
