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.

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.

A leaf mulcher includes a carriage, a plurality of wheels rotatably secured to the carriage, and a main housing having a front and a rear. A scoop is removably coupled to the front of the main housing and configured to direct leaves into the main housing to be mulched. The leaf mulcher also includes an impeller housing having an entry and an exit, where the entry of the impeller housing is coupled to a rear of the housing. In addition, the leaf mulcher includes a bag having an intake conduit coupled to the exit of the impeller housing and is configured to receive mulched leaves, and an impeller is within the impeller housing and has an insert and nut. A motor is coupled to the impeller and is configured to spin the impeller to create a vacuum to draw leaves into the impeller housing where the leaves are mulched.

The present invention provides an improved cutting blade comprising an elongate body portion mountable to a mowing and/or slashing machine having a left side and a right side, said left side and said right side having a leading edge and an opposing trailing edge and a downward portion provided on an outer end of the left side and the right side of the cutting blade, said downward portions having at least one cutting portion, wherein on the left side of the cutting blade, the cutting portion(s) are provided on an inner side of the downward portion and on the right side of the cutting blade, the cutting portion(s) are provided on an outer side of the downward portion. The present invention provides an improved cutting blade having a horizontal body portion with staggered cutting portions.

An agricultural working device, such as a mulcher, is improved with a working rotor which is driven by a drive shaft and a cutting rail with a cutting edge which can be directed towards the working rotor. Sensors for acquiring parameters of working rotor and/or cutting rail are provided. An electronic control apparatus is provided with at least one encoder to set the cutting rail. A method for setting the position of a cutting rail of a working device, such as a mulcher, relative to a working rotor, is configured in such a way that the rotational speed of a drive shaft and the rotational speed of the working rotor are measured and compared with one another. When a ratio of the rotational speeds differs by a predefined threshold, a change in the position of the cutting rail is brought about.

An attachment device, in particular a milling machine and/or a mulcher, for use with a carrier vehicle, includes at least one functional unit which is configured for a supply of energy by way of the carrier vehicle, in order to achieve rapid and/or simple initial start-up, the attachment device has at least one control unit which, in at least one operating state, automatically controls and/or regulates at least one limit value of an operating parameter of the functional unit.

A discharge accessory for a lawnmower includes an inlet end and a hook disposed at the inlet end. The hook defines a channel. A lever arm extends from the hook in a direction transverse to the channel, and a protrusion is disposed in the channel. The protrusion extends in a first direction transverse to the channel and to the lever arm, and the protrusion extends in a second direction transverse to the channel.

Various types of lawnmowers are disclosed that include at least one cutter housing having a chamber wall with a discharge opening therein. The mowers can include a rolling shutter formed of multiple steel sheets held together by pins. In discharge mode, the rolling shutter can be wrapped around a roller cylinder. In mulching mode the rolling shutter can extend to close off the discharge opening of the mower.

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).

An electrically actuated mulch control lever includes an upper plate and a lower plate pivotably mounted together on a top surface of a mower deck. A compression spring is retained between the upper plate and the lower plate urging the upper plate and the lower plate to pivot together. An electric linear actuator is connected to one of the plates, and a mulch gate hinge is attached to the other plate.
