    Abstract: An ice removing attachment for a vehicle includes an ice cutting roller rotatably supported transversely of a vehicle and including a plurality of spaced apart cutting discs having a plurality of circumferentially staggered cutting blades extended transversely between adjacent discs. Forward and rearward scraper blades are supported rearwardly of the roller for scraping away ice cut by the roller. The forward scraper blade has a plurality of teeth along the lower edge thereof defining open spaces between them. The rearward scraper blade has a lower scraper edge which is continuous along at least those transverse positions which follow in the path of the open spaces in the forward scraper blade. The roller and blades may be supported at the front of or beneath the vehicle or both. Roller portions at the front of the vehicle may be made steerable and, in certain embodiments, a toggle mechanism may be provided for rigidifying the vehicle suspension when the ice removing attachment is in operation.
