Abstract

A foldable drill implement has a supply hopper mounted on a center frame section and a rearwardly mounted broadcast hopper extending onto wing frame sections. Various augers connect the supply hopper to the broadcast hopper and maintain a level of fill in the broadcast hopper. Recycling augers return accumulated excess material from outer ends of the broadcast hopper for redistribution to planter drills. Folding of the wing section relative to the center frame section utilizes swing plates and spacer plates to dampen oscillation of the wing sections. Controls regulate flow of material by sensing accumulated excess material and deactuating the augers.
