A two piece scraper blade is provided that includes a scraper member that is releasably connected to a base member. The scraper member can be of a different material than the base member to provide various advantages including with respect to its wear resistance. Further, in one form, a toolless interconnection is provided for ease in attaching the scraper member to the base member. In another form, the scraper member and base member are provided with engaging surfaces with one of the surfaces including teeth for gripping into the other surface when the scraper member is connected to the base member. In this form, the forces for inserting and removing the scraper member from the base member are greater than the form in which a toolless interconnection is provided, and thus a more robust connection between the scraper and base members is provided thereby.
