## CPC

- A01B 61/046: {the device including an energy accumulator for restoring the tool to its working position}
- A01B 21/083: {of the type comprising four individual disk groups each pivotally connected at fixed locations to a substantially rigid frame}
- A01B: SOIL WORKING IN AGRICULTURE OR FORESTRY; PARTS, DETAILS, OR ACCESSORIES OF AGRICULTURAL MACHINES OR IMPLEMENTS, IN GENERAL (making or covering furrows or holes for sowing, planting or manuring A01C5/00; mowers convertible to soil working apparatus or capable of soil working A01D42/04; mowers combined with soil working implements A01D43/12; soil working for engineering purposes E01, E02, E21)

## 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 support 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 through a C shaped resilient element. Stop elements are mounted on the bearing hanger assemblies and to a cross bar to limit deflection of the C shaped elements by abutting some of the secondary frames.

## Claims

### Claim 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 frame members connected to said secondary frames and extending in a fore and aft direction relative to the travel direction;
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;
a resilient structural element connecting the secondary frames to the bearing hangers; and
a plurality of stops each supported by and mounted to at least one of said bearing hangers and being positioned to limit the deflection of the resilient element by abutting at least one of the secondary frames through a frame member; and said stop having a structural element having a generally horizontal plate supporting said bearing hanger assembly, a curved central plate element positioned in a plane parallel to the travel direction and a vertically oriented plate;
a generally transversely extending bar interconnecting said stop elements at the vertically oriented plane so that the deflection of the resilient support is limited by abutment between said transversely extending bar and said frame members extending in a fore and aft direction; and
U-shaped fasteners embracing said transverse bar and being removably connected to said vertically oriented plate.

### Claim 2 (depends on 1)

The agricultural tillage implement of claim 1, wherein the resilient structural element is a C-shaped element connected at one end to said secondary frames and at the other end to said bearing hangers.

### Claim 3 (depends on 1)

The agricultural implement of claim 1, further comprising a scraper/deflector removably fastened to said lower horizontal plate of said stop assembly.

### Claim 4 (depends on 3)

The agricultural implement of claim 3, wherein the lower horizontal plate of said stop assembly is sandwiched between said scraper/deflector and said bearing hanger.
