摘要：The present invention is a grain drill and a method retrofitting a previouslymanufactured grain drill to provide accurate weight determination of seed in a seedhopper of the grain drill. A grain drill in accordance with the invention includes a frame
having a plurality of wheels for supporting the grain drill during rolling over a surface ofground to be planted with seed grain; a hopper for containing the seed grain to beplanted in the ground; a support which is joined to opposed sides of the frame and tospaced apart locations of the hopper to transfer weight of the hopper to the frame, thesupport including at least one weight sensing device which senses a weight of seed grainin the hopper transferred through the support to the frame and provides an output ofthe sensed weight of the seed grain in the hopper; and a display, coupled to the output,for displaying the weight of the seed grain contained in the hopper.
