2	Agricultural implement having diverse hitch and gang operation modes	US15160474	2016-05-20	US09497897B2	2016-11-22	Mark Hennes
An agricultural implement (10) has front and rear gangs (12, 13) of rotatable tillage tools arranged to follow each other along a line of travel. The front and rear gangs (12, 13) are mounted to a main frame (21F), which is mechanically linked to a hitch frame (22) by a self-leveling linkage system (32, 33). The linkage system (32, 33) includes a spring assembly (48) arranged to allow relative movement between the hitch frame (22) and the main frame (21F) when the implement (10) is in a lowered field working position. The linkage system (32, 33) has a pivoting cam (41) for changing the field working preload of the spring assembly (48) to provide multiple hitch operation modes. The linkage system (32, 33) is arranged to make the main frame (21F) level and the hitch frame (22) rigid relative to the main frame (21F) when the implement (10) is in a raised position. The linkage system (32, 33) also includes an adjustable stop device (43) that limits upward hitch movement to provide multiple rear gang hitch operation modes.

8	Multiple-piece wing sections for cultivator and oscillation preventing device for same	US31622972	1972-12-18	US3880241A	1975-04-29	VINCENT JAMES H
An improved farm implement of the foldable, sectional tow type including a central section, including a wheeled cart and wing sections hingedly connected to the central section. Each of the wing sections is comprised of a plurality of hingedly connected frames to allow good ground coverage on abrupt terrain. The sections are further connected to the cart for movement between transport positions and cultivating positions and dampening means interconnect the various frames of the wing section and operable to preclude the same from oscillating relative to each other when in the transport position.

Representative implementations of devices and techniques provide a tool bar comprising a structure having a plurality of sections arranged in geometric forms. The geometric forms may change shape to keep a tool that is attached to the structure in a desired position while the tool bar is being used on uneven terrain, such as on a hillside or while the tool bar is rotated or pivoted at an angle with respect to the direction of travel. Changing the shape of the geometric forms can also result in rotating the tool attached to the structure with respect to the tool bar.
