Abstract

An agricultural tillage implement has a disk frame assembly connected to a pull hitch extending in a travel direction with frame members extending generally laterally with respect to the travel direction. At least one disk blade is connected to and supported by the frame members to till soil over which the agricultural tillage implement traverses. A disk scraper mounting member is connected to at least one frame member. A channel shaped disk scraper is connected to the disk scraper mounting member using a bolted joint connection. The channel shaped disk scraper has a square mounting end adjoining an inner perpendicular surface of the disk scraper mounting member. The channel shaped disk scraper is operable to scrape residue from the at least one disk blade and deflect it away from the travel direction.

First claim

What is claimed is:

1. An agricultural tillage implement, comprising:
a disk frame assembly connected to a pull hitch extending in a travel direction;
said disk frame assembly having at least one frame member extending generally laterally with respect to the travel direction;
at least one pair of disk blades, each disk blade including a convex surface near an edge on one side and a concave surface near the edge on an opposite side, wherein each disk blade is operably connected to and supported by the at least one frame member so that the at least one pair of disk blades are positioned to till soil over which the agricultural tillage implement traverses;
at least one disk scraper mounting member connected to the at least one frame member; and
at least one disk scraper connected to the at least one disk scraper mounting member using a bolted joint connection, the at least one disk scraper having a square mounting end adjoining an inner perpendicular surface of the at least one disk scraper mounting member, the at least one disk scraper positioned between the pair of disk blades such that the disk scraper extends between the at least one pair of disk blades, the disk scraper positioned near the convex surface of one disk blade and near the concave surface of the other disk blade, the at least one disk scraper operable to scrape residue from the pair of disk blades and to deflect it away from the travel direction.

2. The agricultural tillage implement of claim 1 , wherein no portion of the at least one disk scraper contacts the ground.

3. The agricultural tillage implement of claim 1 , wherein the at least one disk scraper mounting member is connected to the at least one frame member through at least one disk blade bearing hanger assembly, the at least one disk blade bearing hanger assembly further functioning to rotatably connect the at least one pair of disk blades to the at least one frame member.

4. The agricultural tillage implement of claim 1 , wherein the at least one disk scraper mounting member is connected to the at least one frame member so that the at least one disk scraper is adjustable relative to the at least one pair of disk blades.

5. The agricultural tillage implement of claim 1 , wherein the at least one pair of disk blades further comprises at least two gangs, each gang including at least one pair of disk blades, and wherein the at least one disk scraper mounting member further comprises a disk scraper mounting member associated with each pair of disk blades on each gang.

6. The agricultural tillage implement of claim 1 , wherein the at least one frame member further comprises at least two frame members, and wherein the at least one disk scraper mounting member further comprises a disk scraper mounting member associated with each of the at least two frame members.

7. The agricultural tillage implement of claim 1 , wherein the agricultural tillage implement is one of a multi-section field disk ripper, a disk harrow, a disk ripper, an in-line ripper, a strip-till, and a vertical tillage implement using disk blades.

8. The agricultural tillage implement of claim 1 , wherein a lower portion of the scraper first contacts the residue when the implement is traveling in the travel direction, and wherein the disk scraper is configured to be positioned such that its end is near a central shaft which extends through each disk blade in order to move residue away from the central shaft.

9. The agricultural tillage implement of claim 1 , wherein the end of the at least one disk blade is configured to extend no lower than a central shaft which extends through each disk blade.

10. The agricultural tillage implement of claim 9 , wherein the disk scraper is U-shaped.
