Harvest sweeper attachment system

A sweep head unit adapted for mounting on a harvester unit having a collection aperture, said sweep head unit comprising;

• an elongated sweep frame, having a proximal end and a distal end, attached at its proximal end to the harvester unit and extending outward and forward to said distal end;
• and
• a rake subassembly rotatably depending within and below said sweep frame;
• wherein
• said rake subassembly includes a proximal rake plate and a distal rake plate, each mounted on a rotational support bearing secured to said sweep frame
• said rake subassembly includes three equally axially spaced tine bars freely rotatably mounted between said proximal rake plate and said distal rake plate, each said tine bar having a plurality of tines depending therefrom;
• and
• said rake subassembly includes three equally axially spaced tine bars freely rotatably mounted between said proximal rake plate and said distal rake plate, each said tine bar having a plurality of tines depending therefrom, said tine bars being freely rotationally connected to respective rotor plates at the proximal and distal ends of said rake assembly, said rotor plates being offset at approximately forty-five degrees from vertical;
• and
• said rake subassembly is caused to rotate with respect to said sweep frame in use such that said tines of each said tine bar the collection aperture sequentially impact and propel desired objects on a surface forward and inward toward said collection aperture.
