CA 2272826

A depth control structure for an agricultural seeder, having laterally spaced opener structures including pivotally mounted opener beams extending rearwardly and downwardly from the seeder frame to journal openers for vertical motion, provides a depth control wheel adjustably supported forwardly of each opener. Each depth control wheel is journaled in the rearward portion of a body beam pivotally supported in its forward portion on the seeder to extend rearwardly with at least its rearward portion below the associated opener beam. The medial portion of the body carries adjustment structure interconnected with the superior opener support beam to fixedly maintain and adjustably vertically position the depth control wheel relative to the associated opener. The depth control wheels have a cylindrical periphery with substantial width to aid in compacting and conditioning the earth that is to define a potential seed furrow for seed placement. The depth wheel moves vertically responsive to vertical motion of the associated opener to provide uniform placement depth for seeds.
