  • Patent number: 6405665
    Abstract: A furrowing tool for an agricultural planter is formed in a modular configuration to provide for paired row seeding operation. The furrowing tool includes a seedbed furrowing member having an edge lying in a flat cutting plane to form a substantially flat seedbed as the furrowing tool is drawn through ground and a fertilizer furrowing member extending below the cutting plane to form an indentation in the seedbed. The seedbed furrowing member is formed with an upper surface extending rearwardly from the edge and with a void between the upper surface and the cutting plane. The furrowing tool further includes a forwardly and downwardly directed fertilizer dispensing passage to direct a stream of fertilizer at a forward direction into the indentation formed in the seed bed. The stream of seeds is also directed forwardly onto the seedbed through the void formed between the upper surface and the cutting plane.
