A mower assembly for cutting and mulching material. The mower assemblycomprises a mowerhousing, a first disc cutter, a second disc cutter and an anvil. The first andsecond disc cutters areorientated such that their outer edges are spaced apart so that counter-rotation of the discs urgesmaterial to move between the discs from an inlet area toward an outlet area.Material travellingfrom the inlet area to the outlet area is subject to cutting and shredding bycutting teeth on the disccutters. Material moving into the outlet area is subjected to further cuttingand shredding throughcontact with the anvil.
