Patent number: 11291158Abstract: 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.Type: GrantFiled: May 1, 2019Date of Patent: April 5, 2022Assignee: HRM Enterprises, Inc.Inventors: Richard Zerbarini, Paul Zerbarini, Robert Zerbarini, David Jalbert

Publication number: 20210282340Abstract: 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.Type: ApplicationFiled: March 9, 2021Publication date: September 16, 2021Inventors: Richard Zerbarini, Paul Zerbarini, Robert Zerbarini, David Jalbert

Patent number: 11006576Abstract: 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.Type: GrantFiled: August 12, 2019Date of Patent: May 18, 2021Assignee: HRM Enterprises, Inc.Inventors: Richard Zerbarini, Robert Zerbarini, Paul Zerbarini

Patent number: 9907226Abstract: 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.Type: GrantFiled: November 14, 2016Date of Patent: March 6, 2018Assignee: HRM Enterprises, Inc.Inventors: Richard Zerbarini, Paul Zerbarini, Robert Zerbarini, Dan Meyer, David Jalbert, Sean Patrick Suiter
