81	Disk harrow with cushion gang	US303290	1981-09-17	US4407372A	1983-10-04	Henry Rozeboom
A harrow that includes a frame having a generally laterally extending rigid beam, a shaft located below the beam, a plurality of spaced disks mounted on the shaft for rotation therewith and a pair of spaced bearing standards for resiliently mounting the shaft on the beam with each standard including a first generally C-shaped spring having an upper portion connected to the beam and the lower portion rotatably supporting the shaft for low disk impact loads and a second C-shaped spring nested within the first C-shaped spring but spaced therefrom, the first spring, as an increasing portion of its C-periphery contacts the second spring, providing therewith a graduated, higher spring rate at high disk impact loads.
82	Yieldable disc blade assembly	US61192	1979-07-27	US4275791A	1981-06-30	Robert B. Rottinghaus
A yieldable disc blade assembly for individual disc blades which prevents structural damage of the disc blades when such blades contact a rock or other obstruction in the field. Once the disc blade is tripped by the force of the blade encountering an obstruction, the assembly requires a decreased force to move the disc blade from the normal working position to the yielding position away from the obstruction.
83	Disk harrow with beam member suspended by U-shaped springs	US659596	1976-02-20	US4066132A	1978-01-03	Gary Allen Rehn
Disk gangs are resiliently suspended from an implement frame by retroverted flat spring members. Flat surfaces of the springs are oriented perpendicularly to the disk blade shaft to thereby permit vertical and fore-and-aft flexing of the disk gangs as obstacles are encountered and yet minimize lateral movement of the gangs to retain gang blade alignment between front and rearwardly positioned disk gangs.
84	S-shaped standard	US3640348D	1970-02-02	US3640348A	1972-02-08	WOMBLE GEORGE E
The use of a resilient standard, or bearing, to support a disc gang from the main frame, with the standard being made of a plurality of curved portions or convolutions, preferably of a reversed ''''S'''' shape.
85	Implement spring cushion	US3620310D	1969-07-22	US3620310A	1971-11-16	RICHEY CLARENCE B
A disc harrow comprises a peripheral frame and pairs of front and rear gangs mounted on gang frames. A foldable wing is provided at the end of each gang to enable folding to a narrower dimension for transport. The inner end of each gang frame mounts a plate having a threaded aperture that receives a bolt pivotally mounted on the implement pull tube. This permits pivotal movement of the gang frame about its longitudinal axis. Each gang frame projects outwardly through a rectangular aperture in the corner of the peripheral frame. A lever centrally pivoted to the peripheral frame corner engages the gang frame at one end. A compression spring unit pivoted to the frame corner is pivoted to the other end of the lever. As the discs encounter an obstruction, the gang frame pivots to lift the discs over the obstruction. This pivots the lever which compresses and pivots the spring unit such that increasing spring compression decreases the lever arm at which the spring acts on the lever. This provides a constant spring force resisting the pivotal movement of the gang frame.

The present invention relates to a loader structure for adjusting the angle of a bucket which prevents a reinforcing member from being deformed by adjusting the position of a boom along with a reinforcing member by rotating a rotary plate when the position of the boom is adjusted. More specifically, the reinforcing member is inserted and connected into the boom to be able to rotate in a lower part of the rotary plate coupled, to be able to rotate, in a link connection part in which a device bracket, a boom, and an arm are connected. A second operator is connected, to be able to rotate, to a connection bracket connected to an upper part of the rotary plate, the operator, and the arm to be able to rotate. If the position of the boom is adjusted by operating the first operator, the rotary plate rotates to prevent the reinforcing member from being deformed. When the position of the boom is adjusted, the position of the reinforcing member is adjusted along with the boom while rotating the rotary plate. Therefore, the reinforcing member is prevented from being deformed by preventing excessive stress from being applied to the reinforcing member.
