Lawnmowers, in particular walk-behind lawnmowers, have a mulching function. A lawnmower discharge deflector guard for a lawnmower has a cutter blade rotatably mounted within a cutting cavity. The cutting cavity is in communication with a discharge chute and has a discharge chute outlet formed in a face of the lawnmower closable by a closure flap. The guard is configured for demountable attachment to the lawnmower adjacent the discharge chute outlet to enclose the outlet and receive, in use, grass cuttings therefrom. The guard forms a substantially air/grass cutting-tight seal with the face of the lawnmower. The guard has an operative inner surface having a substantially vertical portion forming a discharge aperture with the face of the lawnmower and extending below a cutting height of the lawnmower. A lawnmower incorporating the guard is also described.
