Abstract

An agricultural tillage implement including a carriage frame assembly and pull hitch towed by a tractor and secondary frames supported by the carriage frame assembly. The secondary frames mount gangs of disk blades for tilling the soil in a travel direction. Bearing hanger assemblies support the gangs of disk blades below the secondary frames and deflector/scraper elements are mounted on the bearing hanger assemblies for scraping soil and residue from the disk blades and deflecting it away from the travel direction.

Claims

1. An agricultural tillage implement, comprising:

a carriage frame assembly including a pull hitch extending in a travel direction;

secondary frames extending generally laterally with respect to the travel direction; and

,

gangs of disks blades connected to and supported by said secondary frames to till soil over which the tillage implement traverses;

bearing hangers supported from the secondary frames for rotation about an axis generally lateral to the travel direction;

at least one fastener;

a structural element connecting the secondary frames to the bearing hangers; and

a single piece scraper/deflector element positioned horizontally adjacent to the disk blades, said scraper/deflector element being positioned aft of the bearing hangers relative to the travel direction and fastened to the bearing hangers by said at least one fastener extending through said scraper/deflector and connected to said bearing hanger to scrape residue and deflect it away from the travel direction; and

wherein said single piece scraper/deflector element is a flat plate that extends in a horizontal plane when fastened to the bearing hanger.

2. The agricultural tillage implement of claim 1, wherein the structural element for supporting the bearing hanger is a C-shaped element to provide a resilient mounting, said at least one fastener extending through said scraper/deflector and said C-shaped element to said bearing hanger.

3. The agricultural tillage implement of claim 1, wherein the disk blades have a concave and convex side and said scraper deflector is positioned to be adjacent the concave side of the disk.

4. The agricultural tillage implement of claim 3, wherein the scraper/deflector has a curved scraping edge for conforming to the concave side of the disk.

5. The agricultural tillage implement of claim 4, in which the scraper deflector comprises a plate-like element having elongated holes for fastening to the bearing hanger to provide adjustment relative to the concave side of the disk blades.
