Abstract

An attachment assembly for the disc of a mobile agricultural device, including a washer configured to attach to a disc of the mobile agricultural device. The washer may be attached to a center location of the disc. The washer is operatively connected to a deflector bar. The deflector bar substantially prevents debris from accumulating between the disc and a fertilizer assembly attached to the disc, as the disc rotates. The deflector bar in other embodiments, may be directly connected to a fertilizer assembly, rather than to the washer.

Claims

1. An agricultural planter system that deflects trash with a trash deflector, the agricultural planter system comprising:

an attachment body defining an attachment body aperture configured to align with an axis of at least one disc of the agricultural planter system;

a deflector bar operatively attached to the attachment body, wherein the attachment body aperture is configured to position the deflector bar relative to the at least one disc; and

a fertilizer bar associated with the at least one disc, wherein at a first location the fertilizer bar and the deflector bar are spaced from each other at a predetermined distance.

2. The agricultural planter system of claim 1, wherein the attachment body aperture is a bolt aperture configured to receive a bolt for securing the attachment body to the at least one disc along the aperture thereof.

3. The agricultural planter system of claim 1, wherein the deflector bar is stainless steel or plastic.

4. The agricultural planter system of claim 1, wherein the deflector bar is welded to the attachment body at a first end.

5. The agricultural planter system of claim 1, wherein the deflector bar is integrally formed with the attachment body.

6. The agricultural planter system of claim 1, wherein the deflector bar is configured to substantially prevent debris from traveling along the at least one disc towards the attachment body, past the first location.

7. The agricultural planter system of claim 1, wherein the fertilizer bar comprises a fertilizer tube configured to deposit fertilizer in a furrow.

8. The agricultural planter system of claim 1 further comprising:

a hitch bar configured to attach to a tractor, the hitch bar comprising

at least one wheel for supporting the hitch bar as the hitch bar is pulled by the tractor, the at least one wheel is located at a bottom portion of the hitch bar; and

the at least one disc is for creating a furrow, wherein the at least one disc is located at the bottom portion of the hitch bar adjacent to the at least one wheel;

wherein

the attachment body is operatively connected to the at least one disc and the deflector bar is configured to substantially prevent debris from traveling along a complete rotation of the at least one disc.

9. The agricultural planter system of claim 8, further comprising at least one fertilizer assembly operatively connected to the at least one disc, the at least one fertilizer assembly comprising a fertilizer bar operatively attached to a top portion of the at least one disc;

and a fertilizer tube operatively attached to a first end of the fertilizer bar, the fertilizer tube configured to deposit fluids within the furrow created by the at least one disc.

10. The agricultural planter system of claim 9, wherein at the first location the deflector bar and the fertilizer tube are spaced a predetermined distance from each other, and the deflector bar is configured to substantially prevent debris located on the at least one disc from rotating upwards with a rotation of the at least one disc past the first location.

11. The planter system of claim 1, wherein the attachment body comprises a retainer defining the attachment body aperture configured to receive a bolt assembly of the at least one disc.

12. The planter system of claim 10, wherein the deflector bar is operatively attached to a bottom portion of the retainer with the deflector bar angled upwards, such that when the retainer is attached to the at least one disc, the deflector bar is substantially angled towards a top portion of the at least one disc.

13. The planter system of claim 1, wherein the fertilizer bar comprises an attachment portion configured to align with the axis of the at least one disc.

14. The planter system of claim 13, wherein the attachment portion of the fertilizer bar and the attachment body define the same attachment body aperture.

15. The planter system of claim 1, wherein the attachment body comprises a main body and an attachment tab defining the attachment body aperture.

16. The planter system of claim 15, wherein the deflector bar is coupled to the main body.

17. The planter system of claim 1, wherein the axis of the at least one disc defines a disc aperture configured to align with the attachment body aperture.

18. The planter system of claim 1, wherein the attachment body is positioned between the at least one disc and a planter bar, wherein the planter bar is coupled to a planter.

19. The planter system of claim 18, wherein a fastener received through the attachment body aperture secures the at least one disc to the planter bar and the deflector bar.
