Abstract
A planter includes a pair of toothed wheels which sweep mulch away from the path followed by furrow opening discs. The sweeper wheels are carried on the trailing end of a parallel bar linkage attached to a tool bar by which the planter is pulled. As a result of the parallel bar linkage, the sweeper wheels may float upwardly and downwardly independently of the planter frame in order to conform to uneven ground. A spring acts on the parallel bar linkage and may be adjusted either to press the wheels downwardly into the ground if the mulch is hard and dense or to urge the wheels upwardly and relieve some of the weight of the wheels from the ground if the mulch is loose and the underlying soil is relatively fine.
