Abstract:
1. An aerating device for attachment to a self-propelled lawnmower, the aerating device comprising: a frame having a proximal end, a distal end, and a pair of sides extending between the proximal and distal ends; a plurality of tine assemblies mounted for rotation about a tine axis extending through the pair of sides of the frame, each of the plurality of tine assemblies comprising a plurality of tines configured to rotate about the tine axis through first and second spaced apart planes; a platform secured to one of the proximal end or the distal end of the frame to support a user one of in front of or behind the plurality of tine assemblies, respectively, and to facilitate gripping handles of the self-propelled lawnmower, the platform extending from the frame at an elevation that resides in a third plane that is substantially parallel with and located between the first and second planes, wherein weight of an operator on the platform causes rotation of the aerating device about a fulcrum axis; and an attachment mechanism secured to the proximal end of the frame or the platform and configured for attachment to a back end of the self-propelled lawnmower as to permit free rotation of the aerating device relative to the self-propelled lawnmower about the fulcrum axis that extends laterally through the attachment mechanism between the proximal end of the frame and the self-propelled lawnmower substantially transverse to a direction of travel of the self-propelled lawnmower.
