A walk power mower has a traction drive system that includes a front transmission powering a pair of front wheels and a rear transmission powering a pair of rear wheels. A first one of the transmissions provides forward motion of the mower when it is active and a second one of the transmissions provides rearward motion of the mower when it is active. A slidable handle grip on the handle having a cross bar long enough to be gripped by both hands of the user activates the first one of the transmission when it is slid downwardly on a handle out of a neutral position thereof. The slidable handle grip activates the second one of the transmissions when it is slid upwardly on the handle out of the neutral position.

A mower comprises a deck comprising an underside cavity with a first interior profile; and a deck insert mounted within the underside cavity. The deck insert has a deck insert interior with a second interior profile different than the first interior profile.

A lawn mower includes a housing having an opened bottom, a drive source for driving the cutter blade in the housing, a flap provided for the cutter blade in a manner that the flap has a changeable flap angle, a grass clippings container storing cut lawn grass, a grass clippings container weight detection unit for detecting weight of the grass clippings container, and a control unit. The control unit controls at least one of the rotational speed of the drive source and the flap angle of the flap in correspondence with the weight detected by the grass clippings container weight detection unit.

A disc mulcher can be connectable to a carrier vehicle and can include a frame connectable to the skid steer, a spindle, a disc, and a variable speed motor. The spindle assembly can be connected to the frame. The disc can be connected to spindle assembly and can be rotatable relative to the frame about a central axis of the disc and the spindle assembly. The variable speed motor can be connected to the frame and can be indirectly coupled to the spindle assembly. The variable speed motor can be operable to rotate the disc.

A convertible lawnmower with a mulching mode and a discharge mode includes a housing and a mulching system. The housing includes a discharge opening. The mulching system includes a mounting ring and a shutter ring. The mounting ring is coupled substantially concentrically to the housing and includes an upper surface, a lower surface, and a sidewall that extends substantially axially therebetween. The sidewall is formed with a retaining groove and at least one installation groove. The retaining groove extends at least partially circumferentially within an inner surface of the sidewall and each installation groove extends axially from the lower surface to the retaining groove. The shutter ring is only coupled to mounting ring via the retaining groove such that the shutter ring is selectively shiftable between a mulching mode and a discharge mode.

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 drive train for driving the rotor, the drive train including: a drive shaft connected to the rotor; a motor comprising a motor shaft; and a removable wear gear connecting the motor shaft and the drive shaft, wherein the wear gear is formed from a material that is softer than a material of the drive shaft or motor shaft.

A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.

A mower includes a cutting deck supporting a cutting blade having a fixed blade sail and a door having a first position in which the door covers an opening through which grass clippings can pass, and a second position in which the door does not cover the opening. The mower also has a switch configured to send a mode signal indicating that the door is in the first position or the second position. The mower also has a controller configured to receive the mode signal and adjust the cutting blade to rotate at a first speed when the mode signal indicates that the door is in the first position, and a second speed when the mode signal indicates that the door is in the second position. The mower also includes an electric battery to power rotation of the cutting blade.

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.

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.
