The FM9DD, FM14DD and FM18DD are wood chippers specifically designed to chip all kinds of wood that has 
been freshly cut up to diameters of 75mm (FM9DD), 100mm (FM14DD) & 125mm (FM18DD). NOTE: Do not 
insert wood over the diameter specified, roots, trunks or knots, stones, plastic, metal or any other objects that
