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.
