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. A deflector for use with a mobile agricultural tool, comprising:

a disc attachment bar having a first end and a second end and an outer surface opposite an inner surface, with an aperture extending therethrough proximal to the first end, with the aperture configured to attach the disc attachment bar to a disc of the mobile agricultural tool having a portion of the disc attachment bar that includes the second end positioned upwardly and rearwardly relative to the mobile agricultural tool;

a deflector bar operatively attached to the disc attachment bar, which locates the deflector bar relative to the aperture; and

a fertilizer bar operatively attached to the disc attachment bar at the second end, wherein the disc attachment bar positions the deflector bar relative to the fertilizer bar and relative to the inner surface, wherein at a first location the fertilizer bar and the deflector bar are spaced from each other at a predetermined distance established by the relative positions, wherein the deflector bar extends away from the disc attachment bar in a direction that positions an end of the deflection bar below the fertilizer bar and the fertilizer bar extends from the disc attachment bar such that when the disc attachment bar is attached to the disc of the mobile agricultural tool the fertilizer bar lines up with the disc rearwardly allowing fertilizer to be deposited directly behind the disc and the deflection bar aligns with the side of the disc.

2. The deflector of claim 1, wherein the disc attachment bar comprises a bolt aperture configured to receive a bolt for securing the disc attachment bar to the disc.

3. The deflector of claim 1, wherein the deflector bar is stainless steel.

4. The deflector of claim 1, wherein the deflector bar is welded to the disc attachment bar at the first end.

5. The deflector of claim 1, wherein the deflector bar is integrally formed with the disc attachment bar.

6. The deflector of claim 1, wherein the deflector bar is configured to substantially prevent debris from traveling along the disc towards the disc attachment bar, past the first location.

7. The deflector of claim 1, wherein the fertilizer bar comprises a fertilizer tube configured to deposit fertilizer in a furrow behind the disc.

8. The deflector of claim 1, wherein the deflector bar is oil tempered wire.

9. The deflector of claim 1, wherein the deflector bar is operatively attached to a bottom portion of the disc attachment bar.

10. The deflector of claim 1, wherein the disc attachment bar is operatively attached to the disc at a center point of the disc.

11. The deflector of claim 10, wherein the fertilizer bar is directly connected to the second end of the disc attachment bar.

12. The deflector of claim 11, wherein the deflector bar is directly connected to the first end of the disc attachment bar.

13. The deflector of claim 12, further comprising a fertilizer tube operatively attached to one end of the fertilizer bar, the fertilizer tube configured to deposit fluids within a furrow created by the disc.

14. The deflector of claim 13, wherein the deflector bar extends from the first end of the disc attachment bar towards the fertilizer tube.
