Abstract: A mower assembly for cutting and mulching material. The mower assembly comprises a mower housing, a first disc cutter, a second disc cutter and an anvil. The first and second disc cutters are orientated such that their outer edges are spaced apart so that counter-rotation of the discs urges material to move between the discs from an inlet area toward an outlet area. Material travelling from the inlet area to the outlet area is subject to cutting and shredding by cutting teeth on the disc cutters. Material moving into the outlet area is subjected to further cutting and shredding through contact with the anvil.
