Efficiency Meets Versatility

Far more versatile than drum or disk chippers, Rotochopper grinders efficiently process tangled, pliable branches and solid trunks, as well as pre-ground or chipped wood. Best of all, Rotochopper "Perfect In One Pass" technology creates more opportunities for wood waste by delivering the particle size, texture, and even color you need to meet market demands for fuel, animal bedding, and colored landscape mulch
