Abstract
A convertible lawnmower with a mulching mode and a discharge mode includes a housing and a mulching system. The housing includes a discharge opening. The mulching system includes a mounting ring and a shutter ring. The mounting ring is coupled substantially concentrically to the housing and includes an upper surface, a lower surface, and a sidewall that extends substantially axially therebetween. The sidewall is formed with a retaining groove and at least one installation groove. The retaining groove extends at least partially circumferentially within an inner surface of the sidewall and each installation groove extends axially from the lower surface to the retaining groove. The shutter ring is only coupled to mounting ring via the retaining groove such that the shutter ring is selectively shiftable between a mulching mode and a discharge mode.
