A lawn mower includes a deck structure having, in an embodiment, a baffle with teeth at a front end of the deck structure opposite to a discharge opening for directing vegetation to be cut into the pathway of a blade. A trim divider edge portion, in an embodiment, prevents long vegetation from sliding around the edge of the deck structure. A trim vacuum structure portion, in some embodiments, in the form of an inclined surface at the rear end of the deck structure opposite a side of the discharge opening or at a center location of the deck structure reduces pressure within the deck structure for lifting vegetation to be cut.

A mulch kit control lever includes a handle pivotably mounted to a support plate with a tension spring connecting the handle to the support plate and urging the handle to pivot to either a mulching position or a side discharge position relative to the support plate. The tension spring is connected before the mulch kit control lever is installed on the mower deck. A retainer slides in a slot in one of the support plate and the handle preventing over-travel of the handle past the mulching position and the side discharge position.

A lawn mower includes a blade assembly configured to perform a cutting function, a deck formed with an accommodating space for accommodating at least part of the blade assembly and a power mechanism configured to drive the blade assembly to rotate about a rotation axis. The blade assembly includes a cutting blade and a chopping device. The cutting blade is configured to be driven by the power mechanism to rotate about the rotation axis, and the cutting blade includes a cutting edge. The chopping device includes a chopping body, a plurality of chopping teeth, and a plurality of branching ports provided between two adjacent ones of the plurality of chopping teeth. The chopping body is configured to be driven by the power mechanism to rotate and the chopping teeth extend upward or downward from the chopping body.

Uneven distribution of grass clippings in a grass clippings receptacle of a lawn mower can be minimized. A lawn mower includes: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive mowed grass clippings; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to open and close the grass clippings transport passage and an actuator configured to open/close-drive the shutter; a controller configured to control the shutter device; and a speed sensor for detecting a travel speed of the lawn mower, wherein the controller is configured to open/close-control the shutter device based on the travel speed.

A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a liner mounting system for mounting a replaceable wear liner between the rotor and the inner wall, the liner mounting system including: an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner; and a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall.

A mower assembly for cutting and mulching material. The mower assembly comprises a mower housing, a first disc cutter, a second disc cutter and an anvil. The first and second disc cutters are orientated such that their outer edges are spaced apart so that counter-rotation of the discs urges material to move between the discs from an inlet area toward an outlet area. Material travelling from the inlet area to the outlet area is subject to cutting and shredding by cutting teeth on the disc cutters. Material moving into the outlet area is subjected to further cutting and shredding through contact with the anvil.

The present disclosure is directed to a mulch plug configured to attach to a lawnmower by one or more attachment points, including a snap-fit attachment point. The snap-fit provides a more secure attachment to the lawnmower than attachment mechanisms on existing mulch plugs, in turn providing more even distribution of mulch and less clogging and locking of mower wheels.

A shutter assembly for a lawnmower can include a cutter housing, a shutter, and a lever. The shutter can be rotatably attached to the cutter housing so as to be movable between (a) a first shutter position in which a blocking panel is positioned such that the blocking panel opens the discharge opening, and (b) a second shutter position in which the blocking panel is positioned such that the blocking panel closes the discharge opening, and the second shutter position corresponds to a mulching position. The lever can be attached to the shutter and extend through the cutter housing slot. The lever can move the shutter between the first shutter position and the second shutter position. The lever can include a handle knob assembly that includes a button that is biased, by a spring, to lock in any one of a plurality of positions on the cutter housing.

A mower capable of reducing noise generated by rotation of a cutter blade is provided. A mower is provided with an upper cutter blade and a lower cutter blade (15) inside a housing. The lower cutter blade has a wing portion (42) and a wing chamfered portion (51). The wing portion overhangs upward from a second rear end portion (47) of the lower cutter blade on an opposite side in a rotational direction, at both end portions (45) in a longitudinal direction. The wing chamfered portion is chamfered so that a wing outer end portion (53) of the wing portion is inclined from an upper surface to a lower surface.

A mower deck to be mounted on a traveling vehicle is disclosed. The mower deck includes a housing having a top wall, at least one blade rotated downwardly of the top wall and about a vertical shaft, and a blade baffle unit extending downwards from the top wall in such a manner as to surround an outer circumferential area of a rotational path of the blade to create therein a mulching blade rotation space, the blade baffle unit having a front baffle located on an advancing side of the traveling vehicle and a rear baffle located on a reversing side of the traveling vehicle. The front baffle extends downwards from the top wall to exceed the rotational path so as to prevent discharge of cut grass pieces via a lower end of the front baffle. The rear baffle extends downwards from the top wall by such an extent to allow discharge of the cut grass pieces.
