  • Patent number: 4671193
    Abstract: A planting tool especially for minimum tillage operations has a leading rolling coulter and an elongated, rigid knife behind the coulter to hold open a slot cut in the soil by the coulter. Blades mounted on the vertical knife cut lateral slices in the soil extending outwardly from each side of the slot and between the soil surface and the slot bottom. A fertilizer conduit deposits a band of fertilizer in the bottom of the slot and seeds gravitate through a seed tube onto a V-shaped deflector which directs them in both directions into the lateral slices in the soil. Press wheels mounted on the knife close and recompact the soil after the seeds are planted outwardly and above the band of fertilizer in the slot. The press wheel also serves as a gauge in conjunction with a flexible tool mount to regulate the depth of operation of the tool components relative to the soil surface.
