Abstract: A cutter housing for a lawnmower can include first and second cutting chambers with first and second chamber walls and first/second discharge openings. First and second ring gates that have openings and blocking segments can be concentrically placed within respective first and second chamber walls, and rotatably attached to the cutter housing. The first and second ring gates can be rotated between: (a) an opened position in which the first/second ring gate is positioned with the first/second ring opening having a first overlap with a first/second discharge opening to provide a discharge mode, and (b) a closed position in which the first/second ring gate is positioned with the first/second ring opening having a decreased overlap, relative to the first overlap, with the first/second discharge opening to provide a mulch mode. The ring gates can be stopped at intermediate positions to provide a partial mulch mode or partial discharge mode.

Abstract: A lawn mower and a cutter housing assembly can include a cutter housing, a first and second rotation arms, and first and second plates pivotably attached to the cutter housing. The first plate and second plate can be selectively rotatable between: (a) a discharge mode in which the plates are positioned a first distance from the front wall of the cutter housing to provide a first gap, and (b) a mulch mode in which the plates are positioned a second distance greater than the first distance from the front wall to provide a decreased gap. A first actuator and second actuator can be connected to the first and second rotation arms to cause rotation of the first and second rotation arms when actuated. Actuation of the first actuator and second actuator can cause the first plate and second plate to move between the discharge mode and the mulch mode.

Abstract: The disclosed subject matter is directed to a lawnmower that can include a cutter housing with a first chamber wall defining a first cutting chamber. A first discharge opening can be located in the chamber wall, and the cutter housing can include a slot arrangement. A conversion assembly can include an adjustable wall slidably attached to the cutter housing so as to be selectively movable within the slot arrangement between an opened position and a closed position to place the lawnmower in either a discharge mode or a mulch mode (or somewhere in between).

Abstract: Various types of lawnmowers are disclosed that include a cutter housing having a chamber wall and a discharge opening therein. A mulch gate can be provided with an interior scroll-shaped face and can be pivotably attached to the cutter housing so as to be movable between an opened gate position and a closed position. In the opened position, the mulch gate is positioned such that the discharge opening is opened to an exterior of the lawnmower to allow clippings to pass therethrough and out of the lawnmower. In the closed position the mulch gate closes the discharge opening to provide a mulch mode in which clippings remain in the cutter housing for added cutting by the lawnmower blade. When the mulch gate is in the closed gate position, the interior scroll-shaped face of the mulch gate can be substantially continuous with a wall interior surface of the chamber wall.

Abstract: A discharge guard assembly for a mower includes a cutter housing having an opening for discharging cuttings. A guard is hingedly attached to the housing so that the guard can move between a closed position and an open position. A latch contacts a stop on the guard to hold the guard in the closed position to allow the mower to operate in a mulching configuration. The latch is movable to an unlatched position in which the guard is free to rotate to the open position to allow cuttings to be discharged through the opening in the housing.

Abstract: An anti-rotation apparatus usable with power driven equipment. The power driven equipment may include a deck, a deck bracket connected to the deck, and a handle. The handle may be pivotally mounted to the deck bracket and capable of rotating in a first direction and a second direction opposite the first direction. The anti-rotation pin has a first portion configured to prevent rotation of the handle in the first rotational direction; and a second portion configured to prevent rotation of the handle in a second rotational direction opposite the first rotational direction.
