Brontosaurus

A piece of large equipment used for land clearing. The brontosaurus cutting head is a spinning drum that grinds shrubs and small diameter trees into small wood fiber mulch.  Free-spinning cutting teeth are arranged in parallel rows on the drum.  As the drum rotates at high speed, centrifugal force causes the cutting teeth to stand up and contact material being cut. The cutting head is usually attached to the arm of a modified excavator.
