Abstract
A multi-row seed planter has a seed hopper for each row and may also have a herbicide and/or insecticide hopper for each row. The hoppers have generally rectangular top openings the rims of which are tubular in cross-section and referred to as 'perimeter tubes'. The closure lids for the hoppers slide on and off from the hopper openings. When each lid reaches its fully closed position it snaps into place and cooperating formations on the lid and perimeter tube retain it in its fully closed position against agitation and vibration during planter travel.
