Abstract: A debris receiving receptacle is mounted to the rear portion of a garden tractor or riding mower having a discharge outlet. Interconnecting the mower discharge outlet and receptacle is a conduit comprising, in rearward order, an outlet adapter, an extension member, an elbow having a fore and aft leg telescopingly receiving the extension member and a transverse leg discharging to the receptacle. The elbow is rotatably mounted on the receptacle frame to permit easy removal of the extension member for removing blockages. In a second embodiment the receptacle includes a frame defining an opening disposed about the periphery of the transverse leg, a porous outer shell member and an air impervious bag disposed within the outer shell member and clamped to the frame at its open end.
