  • Track cleaner and grinder head attachment
    Patent number: 11821156
    Abstract: The present invention is a grinder head for attaching to a track cleaner. The present invention also includes the grinder head attached to a track cleaner. Preferably, the present invention will continuously grind and load hard frozen minerals like taconite or ice. In addition, the present invention preferably aids in removal of hard-to-handle material such as wet, sticky bentonite from tracks which can be difficult in the summer months. The grinder head attachment will preferably allow operators to use a track cleaner to remove materials, preferably in one pass, during the colder months when the bentonite is frozen and much easier to handle. Preferably, the present invention will also be able to remove concrete or asphalt surfaces at road crossings.
