  • Patent number: 5417171
    Abstract: A seed and fertilizer boot is mounted on a conventional cultivator shank. The boot has side-by-side fertilizer and seed tubes. One tube leads to a downwardly and rearwardly sloping delivery spout while the other delivery tube projects below the delivery spout. A flat knife is mounted on the front of the straight delivery tube to form a narrow furrow immediately in front of the associated delivery tube for receiving seed or fertilizer from the tube. The knife is adjustable along the tube so that its depth can be adjusted to compensate for wear. A second knife extends along the front face of the delivery spout to form a second furrow immediately beside the first furrow. This closes the first furrow and packs the soil onto the planted seed or fertilizer. The second knife also provides a shallower furrow for planting fertilizer or seed as the case may be. Like the first knife, the second knife is adjustable. Where desired, a skid-type packer can be mounted on the shank to close the furrows.
