Abstract

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.

Abstract

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.

Abstract

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.
