Abstract

An extension for use with a furrow opener is disclosed for properly placing seeds in a furrow. The extension attaches to the furrow opener to help direct bouncing seeds into the vertex in the bottom portion of the furrow. The extension comprises an elongated flexible body member defining a general arcuate shape, and also defines an upper segment and a lower segment. The upper segment defines an attachment structure for releasable engagement to the furrow opener. The lower segment depends downwardly and rearwardly from the furrow opener and extends into the furrow. The lower segment has a width dimension decreasing continuously along its length, the width dimension substantially equal to but less than the width of the furrow along the length of the extension. The extension does not contact the furrow. The lower segment terminates at a trailing end, which is spaced above the centrally located bottom portion of the furrow.

2. An extension as defined in claim 1, wherein said lower segment has a downwardly facing concave lower surface.

3. An extension as defined in claim 2, wherein said downwardly facing concave lower surface transforms along the length of the lower segment of the extension to a downwardly facing planar lower surface at said trailing end.

4. An extension as defined in claim 1, wherein said lower segment defines laterally extending and downwardly curving shoulder flanges.

5. An extension as defined in claim 1, wherein the furrow opener is a planter having a seed tube, with the extension attachable to the seed tube.

d. said lower segment terminating at a trailing end, said trailing end configured to be spaced above the centrally located bottom portion of the furrow.

8. An extension as defined in claim 7, wherein the seed tube has a downwardly depending lower end and a rearwardly facing surface, and wherein a protrusion extends from the rearwardly facing surface adjacent to the lower end of the extension, and wherein said attachment structure further comprises:

a. an aperture formed in said upper segment of said extension to receive the protrusion; and

b. a releasable fastener to secure said extension to the seed tube.

9. An extension as defined in claim 8, wherein said attachment structure further comprises:

a. a longitudinal slot formed in said upper segment of said extension; and

b. an insert fixedly positionable in said slot, and defining said aperture for receiving the protrusion.

10. An extension as defined in claim 8, wherein:

a. said insert is positionable in said slot at a plurality of fixed positions along the length of said slot to adjust the amount the extension extends beyond the seed tube.

11. An extension as defined in claim 9, wherein:

a. said slot defines laterally opposing, inwardly facing sidewalls defining a first sawtooth pattern;

b. said insert defines laterally opposing, outwardly facing sidewalls defining a second sawtooth pattern corresponding to said first sawtooth pattern; and

c. said insert positionable in said slot such that said first and second sawtooth patterns mate together and fixedly position said insert in said slot.

12. An extension for properly placing seeds in a furrow for use with a drill having a furrow opener for creating a seed furrow having at least one disk blade, a chute for dropping the seeds into said seed furrow, and a closing device for closing said seed furrow, a scraper apparatus attached to the furrow opener for cleaning the disk blade, and the seed furrow having a centrally located bottom portion and upwardly and outwardly extending sidewalls defining a maximum width dimension, and the sidewalls intersecting at the vertex of the bottom portion and defining a minimum width dimension said extension comprising:
