A lawnmower (10) capable of being switched between a bagging mode and a mulching mode is disclosed. The lawnmower includes a shutter mechanism (40) provided on an internal peripheral surface of a housing (11) which opens downward for storing a cutting blade (14). The shutter mechanism (40) is switched, by the operation of the shutter mechanism (40), between a bagging mode for delivering cut grass from the housing (11) to a cut grass storage container (22) and a mulching mode for discharging the cut grass out below the housing (11). The shutter mechanism (40) has a kicker (47) on a shutter body (42) positioned in the interior of the housing (11). The kicker (47) guides the cut grass to the bottom of the housing (11) during the mulching mode.
