The present invention relates to lawnmowers, in particular to walk-behind lawnmowers having a mulching function. We describe a lawnmower discharge deflector guard (10) for a lawnmower having a cutter blade (21) rotatably mounted within a cutting cavity (22), wherein the cutting cavity is in communication with a discharge chute (24) and having a discharge chute outlet formed in a face of the lawnmower closable by means of a closure flap (25) wherein the guard (10) is adapted for demountable attachment to the lawnmower adjacent the discharge chute outlet to enclose said outlet and receive, in use, grass cuttings therefrom, wherein the guard (10) forms a substantially air/grass cutting-tight seal with said face of the lawnmower and wherein the guard has an operatively inner surface having a substantially vertical portion forming a discharge aperture (35) with said face of the lawnmower and extending below a cutting height of the lawnmower. We also describe a lawnmower incorporating the guard (10).
