New to mulcher teeth? Start with how to choose the right tooth for your terrain. Also stocking teeth for Diamond Mowers heads. Several of these teeth also fit Rayco mulcher teeth. Aftermarket teeth and knives for Caterpillar forestry mulchers, shipped from the US. The same teeth fit CAT HM series heads and FAE rotors, which is why each product is named for the rotor it fits: C/3, C/1, Type C, Type E, Mini and Max, in carbide and steel, with interchange numbers on every listing. The Top Sharp Knife for FAE Max also fits CAT machines with the newer BL rotors (BL4, BL5, HM6015). Not sure which rotor your head has?
