US Patent 7448195 Lawn mower attachment for controlling discharge flow

A lawn mower attachment for controlling lateral discharge of clippings expelled from a discharge chute of a mover is disclosed. The attachment includes a flap pivotably attached to the discharge chute, a control bracket secured to an exterior surface of the lawn mower, and a rod. A first end of the rod is secured to the flap, and a free second end of the rod extends outwardly from the control bracket. The rod extends through and is slideably disposed within a channel in the control bracket. Movement of the second end away from the control bracket pivots a distal edge of the flap away from the discharge chute, while movement of the second end toward the control bracket pivots the distal edge of the flap toward the discharge chute.
