摘要： A yard waste clearing device includes a horizontal cross-flow fan blade assembly. The cross-flow fan blade assembly is disposed in a housing that operated in concert to produce an airflow from an inlet portion of the housing, through the cross-flow fan blade assembly, and out an outlet portion with a sufficient flow rate to carry plant matter shredded by the cross-flow fan blade assembly to a storage element such as a disposable yard waste bag. A vertical chute from the outlet portion carries the shredded plant matter up to the opening of the yard waste bag so that the yard waste bag may be held vertically, utilizing the available storage space more efficiently.

摘要： A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.

摘要： A lawnmower uses thin, replaceable blades with a hardened cutting edge and a cross-section defining an airfoil retained in cartridges that are inserted and removed from rotors in a blade assembly at need. The cartridges comprise a blade and rotor interlocking elements affixed to the blade, each rotor interlocking element corresponding to one rotor in the blade assembly. Each rotor and rotor interlocking element includes features that allow the two to be securely engaged so that the rotors may be spun quickly in a mower blade assembly to cut grass.

摘要： A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of blades in a blade channel. The blade assembly is covered by a blade assembly guard that is only open underneath at a point where blades in the blade assembly would cut grass during normal operation. A blade assembly access panel in the upper portion of the blade assembly guard allows blades or a blade assembly to be easily replaced.

摘要： A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of multi-ductility blades with a maximum thickness of 0.075 inches in a blade channel and in a substantially tangential orientation. The multi-ductility blades include a hardened cutting edge of Rockwell hardness greater than 50 and ductile portion with Rockwell hardness less than 50.

摘要： A lawnmower uses thin, replaceable blades with a hardened cutting edge and a cross-section defining an airfoil. Such blades are held by blade holding elements in a horizontally rotating mower blade assembly. The blade assembly and blade assembly housing are configured in a specialized cross-flow mower assembly to reduce grass leave tip damage, increase cut quality and overall aesthetic appeal, and create a cross-flow air current while consuming less power and providing a reduced environmental impact.

摘要： A blade cartridge for a horizontal rotary mower includes airfoil blades and diverter blades that alter airflow within the blade cartridge and prevent grass clippings from accumulating. The horizontal rotary lawnmower may be adapted to engage a cleaning station with brushes or cleaning pads to remove grass clippings while the horizontal rotary lawnmower blade assembly is operated in reverse. The cleaning station may automatically engage a reverse operation. The cleaning station may also hone the blades of the blade assembly while operating in reverse.
