The 500 series Baumalight Brush Fire brush mulchers will efficiently mulch heavy brush and small trees and are offered with two different types of teeth. The Planer style teeth feed their appetite for brush bit by bit, taking small bites and providing the most efficient mulching and cutting. The Ripper style teeth have more of a shredding mulching action. Their v-shaped design makes them less susceptible to impacts with hard objects like stones, making them the better choice when mulching below grade and in fence lines.
