摘要：
A planter unit for planting seeds as it traverses a field in a direction of travel includes a seed delivery tube and a furrow opener configured to open a furrow in the soil for receiving seeds dropped through the delivery tube. A gauge wheel assembly controls the depth of penetration of the furrow opener. The planter unit also has a furrow closing tool that closes the furrow, the furrow closing tool positioned after the delivery tube in the direction of travel. The planter unit also has a row cleaning and depth control tool positioned after the furrow closing tool. The row cleaning and depth control tool has first and second row whippers that push excess soil out away from above where seeds were dropped in the furrow, wherein vertical position of first and second row whippers is selectively adjustable relative the vertical position of the furrow opener.
