Abstract

A shank assembly for an agricultural tillage implement including a shank, a point removably connected to the shank, and a protective guard removably connected in between the point and the shank. The point retains the protective guard on the shank. The protective guard is configured for protecting the shank and flexing in response to a movement of the shank.

First claim

The invention claimed is:

1. A shank assembly for an agricultural tillage implement, comprising:
a shank;
a point removably connected to the shank through a fastener; and
a protective guard removably connected in between the point and the shank wherein the protective guard is secured onto the shank by the fastener which mounts the point to the shank, such that the point retains the protective guard on the shank, and the protective guard being configured for protecting the shank and flexing in response to a movement of the shank.

2. The shank assembly of claim 1 , wherein the protective guard comprises a front surface and a rear surface, the front surface at least partially contacts the point and is at least partially covered by the point, and the rear surface contacts the shank.

3. The shank assembly of claim 2 , wherein the protective guard comprises a protective guard body with an upper portion and a lower portion which connects in between the point and the shank.

4. The shank assembly of claim 3 , wherein the upper portion comprises an upper shape with a crop-engaging protrusion for engaging and diverting a soil from contacting the shank, and the lower portion comprises a lower shape that is different than the upper shape.

5. The shank assembly of claim 3 , wherein the lower portion comprises at least one through hole for receiving the fastener therethrough, and the fastener jointly mounts the point and the protective guard to the shank.

6. The shank assembly of claim 5 , wherein point at least partially covers the lower portion but does not cover the upper portion.

7. The shank assembly of claim 5 , wherein the fastener exclusively mounts the point and the protective guard to the shank.

8. The shank assembly of claim 1 , wherein no other mounting hardware is used to secure the protective guard to the shank except that which is used to connect the point to the shank.

9. The shank assembly of claim 1 , wherein the protective guard is non-metallic.

10. The shank assembly of claim 9 , wherein the protective guard comprises an ultra-high molecular weight (UHMW) polyethylene.

11. An agricultural tillage implement for an agricultural vehicle, comprising:
a frame; and
a shank assembly connected to the frame, comprising:
a shank;
a point removably connected to the shank through a fastener; and
a protective guard removably connected in between the point and the shank wherein the protective guard is secured onto the shank by the fastener which mounts the point to the shank, such that the point retains the protective guard on the shank, and the protective guard being configured for protecting the shank and flexing in response to a movement of the shank.

12. The agricultural tillage implement of claim 11 , wherein the protective guard comprises a front surface and a rear surface, the front surface at least partially contacts the point and is at least partially covered by the point, and the rear surface contacts the shank.

13. The agricultural tillage implement of claim 12 , wherein the protective guard comprises a protective guard body with an upper portion and a lower portion which connects in between the point and the shank.

14. The agricultural tillage implement of claim 13 , wherein the upper portion comprises an upper shape with a crop-engaging protrusion for engaging and diverting a soil from contacting the shank, and the lower portion comprises a lower shape that is different than the upper shape.

15. The agricultural tillage implement of claim 13 , wherein the lower portion comprises at least one through hole for receiving the fastener therethrough, and the fastener jointly mounts the point and the protective guard to the shank.

16. The agricultural tillage implement of claim 15 , wherein the fastener exclusively mounts the point and the protective guard to the shank.

17. The agricultural tillage implement of claim 11 , wherein no other mounting hardware is used to secure the protective guard to the shank except that which is used to connect the point to the shank.

18. The agricultural tillage implement of claim 11 , wherein the protective guard is non-metallic.

19. The agricultural tillage implement of claim 18 , wherein the protective guard comprises an ultra-high molecular weight (UHMW) polyethylene.
