Abstract
Abstract The grass catcher assembly includes an adaptor plate attached to the lawn mower housing above the discharge orifice, the plate having a base portion and an inwardly formed lip overhanging the base portion to provide a hook. The catcher bag frame includes a rigid, projecting loop engageable with the hook to support said catcher bag frame. The loop is attached to the outwardly extending, bag supporting portion of the frame so as to provide spaced points of support transferring the weight of the catcher bag to the lawn mower housing. The adaptor plate includes spaced side abutment portions cooperating with the loop to preclude sideways movement between the loop and the adaptor plate.
