A scarifying blade for use on earthmoving equipment (e.g. a road grader). The lower working edge of the blade has attached to it several spaced rotatable bits, and attached to at least one of the ends of the blade is an end rotatable bit at an angle of about 30 to 60 degrees relative to the spaced bits on the lower edge of the blade. The end bits prevent loosened material from spilling around the end of the blade and they also provide other additional advantages.
