A vehicle-mounted ice-scraping mechanism includes a tool carrier mounted on the vehicle, and a plurality of non-rotatable ice-scraping tools mounted on the tool carrier and depending downwardly therefrom. Each tool includes a shank mounted to the tool carrier, and a cutting head depending downwardly from the shank. The cutting head is formed of a steel main body, and a carbide insert is mounted in the steel body at a location spaced from a front end of the steel body. During a wear-in period, front and bottom surfaces of the steel body define a rake face and a clearance face, respectively, of the tool. After the wear-in period, front and bottom surfaces of the insert define the rake face and clearance face, respectively. The tool is oriented such that the shank and the rake face extend upwardly and forwardly to define a positive rake angle. The tool shanks are cylindrical and are mounted in cylindrical bores in the tool carrier. The cutting heads are situated so closely together that they abut one another and thereby prevent rotation of the tools relative to the tool carrier.
