Abstract
An apparatus for cutting and breaking rock includes a cutting disc (13) having an attached wedge (11). Cutting disc (13) can be rotated by shaft (16) to cut a groove into rock. After a pre-determined distance, wedge (11) is forced into the cut groove to cause the rock above the groove to be broken away. Shaft (16) is powered by a drive motor, and can include a kick back mechanism to prevent wedge (11) from being trapped in the cut groove. The entire apparatus can be mounted to the three point linkage of a tractor.
