The asparagus picking machine of the present invention comprises a frame assembly which is adapted to be carried by a vehicle adjacent to the ground. A continuous picker belt assembly is mounted on the frame assembly and is trained around a forward sprocket, a rearward sprocket and a chain guide means which is located between and below the two sprockets. The picker belt assembly comprises a plurality of elongated spaced apart parallel picker bars extending parallel to the rotational forward and rearward axes of the sprockets. The belt assembly includes chains which interconnect the spaced apart picker bars. The chains are trained around the forward and rearward sprockets and are guided through the guide means so as to travel in a downward and rearward inclined path from the forward sprocket to the guide means and then through an S-shaped pattern as the chain passes through the guide means. The asparagus protruding upwardly from the ground extends between the spaced apart picker bars and is snapped off when the picker bars move into the S-shaped pattern caused by the guide.
