  • Combination grass discharge and mulch plug insert apparatus and method for a lawnmower
    Patent number: 8015785
    Abstract: A combination grass discharge and mulch plug insert apparatus and method are provided where the insert can include a first end configured for communication with a discharge opening of a lawnmower and a second end also configured for communication with the discharge opening. The first end can be configured for preventing discharge of grass clippings from the lawnmower, whereas the second end can be configured for allowing discharge of grass clippings through the second end. Further, the insert can be reversible such that it can be oriented in either a first position in which the first end is inserted into the discharge opening or a second position in which the second end is attached to the discharge opening. As a result, the lawnmower can be easily converted between mulching and side- or rear-discharge modes of operation.
