Abstract

A resilient seed firming attachment for a planting machine designed to effectively place seed at a consistent depth and at consistent spacing. The attachment may be of any geometrical configuration having a length adequate to firm the seed in the opened furrow and is mounted in a position trailing the discharge end of a seed boot. The resilience of the seed firming attachment being variable and having a control mechanism to ensure that sufficient force is applied to the seed to firm it into the soil at the desired planting depth. By controlling the amount of flex, the proper seed planting depth and firming will be accomplished in a variety of soil and moisture conditions. The seed firming device is also variable so that the amount of down pressure will not modify the depth desired and obtained by the furrow opening device.

Claims

1. A planting assembly having a furrow opening mechanism, a seed dispensing means, including a seed tube for directing the seeds downwardly and rearwardly as the planting assembly moves forward, and structure for guiding and firming seeds in the furrow as seeds are deposited, comprising:

a flexible member with first and second ends;

means for attaching and supporting said first end of said flexible member on the planting assembly with the second end of said flexible member extending downwardly and rearwardly applying downward pressure in the bottom of the furrow to firm the seeds in the soil;

said flexible member includes a first, second and third section;

the first section, which includes said first end, being inflexible, the second section of said flexible member being flexible and located between said first and said third sections, said second section including means for varying the flex of said second section, and the third section, which includes said second end, is inflexible.

2. The invention in accordance with claim 1, wherein said means for varying the flex of the second section of said flexible member are cut-outs in the second section.

3. The invention in accordance with claim 2, wherein said means for varying the flex of said second section of said flexible member includes means for flex at a predetermined value.

4. The invention in accordance with claim 1, wherein said third section of said flexible member conforms to the bottom of the furrow.

5. The invention in accordance with claim 1, wherein said third section has a width sufficient to assist the seed tube in preventing the bounce of seeds in the furrow.

6. The invention in accordance with claim 1, wherein said third section has a cross-section equal to a width of the burrow.

7. The invention in accordance with claim 1, wherein said flexible member flexes between said first and second ends due to the weight of the planting assembly forcing the flexible member against the soil at the bottom of the furrow.

8. The invention in accordance with claim 1, wherein said second section of said flexible member flexes sufficiently to permit said third section to become horizontal at the bottom of the furrow.

9. The invention in accordance with claim 3, wherein said second section of said flexible member has a memory which returns the second section to an un-flexed state when flexing force is removed.

10. The invention in accordance with claim 1, wherein said means for supporting the first end of said flexible member on said seed tube assembly and retaining said flexible member attached to the assembly resist the forces applied to the third portion of said flexible member by the resistance of the soil against the weight and lateral movement of the planting mechanism.

12. The invention in accordance with claim 1, wherein said flexible member is a unitary member made of plastic.

13. The invention in accordance with claim 3, wherein said means for controlling the flex of said second section includes a position adjustable rigid member inserted in one of said geometric cut-outs to limit the flex of said cut-out.

11. The invention in accordance with claim 11, wherein said means for retaining said flexible member are straps removably attached to said seed tube assembly.
