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 and achieve more effective removal of the mulch without significantly disturbing the soil. The forward location of the sweeper wheels enables a coulter to be mounted on the planter frame and slice vertically into the ground ahead of the furrow opening discs.
