Abstract
Apparatuses and methods for changing the mode of operation for a lawnmower can include a door assembly having a shutter door pivotably movable with respect to a discharge opening of the lawnmower between a closed position in which it obstructs the discharge opening and an open position in which the discharge opening is substantially unobstructed. A handle can be positioned adjacent to an upper surface of the mower deck of the lawnmower and coupled to the shutter door, wherein the handle is pivotably movable with respect to the upper surface to cause movement of the shutter door. A locking member can be positioned between the handle and the upper surface, the locking member being movable with respect to the handle and operable to retain the handle in one of a plurality of predetermined positions corresponding to the closed positions and open position of the shutter door.
