There is disclosed an earth cutting apparatus (200) comprising a plurality of articulated elements (210, 212) including at least a first element (210) having a mounting structure (214) thereon and an adjacent second element (212) hingedly connected to the first element (210). An earth cutting member (216) is provided including a proximal end (216.1) which is pivotally mounted to the mounting structure (214) of the first element (210) and an earth cutting end (216.2). The earth cutting member (216) is slidably connected (218) to the adjacent second element (212) and moveable between an extended position (220) and a retracted position (222), such that hinged movement of the adjacent second element (212) relative to the first element (210) causes the earth cutting member (216) to slidably extend from the adjacent second element (212) to the extended position (220) for operatively cutting earth. Hinged movement of the adjacent second element (212) in an opposite direction causes the earth cutting member (216) to slidably retract to the retracted position (222).

A dynamic linkage for a tool gang on a multi-row agricultural implement. The tool gang can include one or more ground-working or other agricultural tools, which are mounted on a tool gang frame. The tool gang frame is connected to a toolbar by the dynamic linkage, each includes adjusting mechanisms for limiting vertical travel and down-pressure forces applied to the tools. The dynamic linkage is configured for tripping to raise the tool gang for clearing a surface or subsurface obstacle.

A tillage device includes a soil disruptor configured to couple to an agricultural implement. The soil disruptor is sized and shaped to create a soil disruption in a target soil profile beneath a soil surface without tilling the soil surface when the soil disruptor is moved through the target soil profile by the agricultural implement.

A tillage point for an agricultural implement includes a body extending in a lengthwise direction between a tip end and a retention end and in a vertical direction between an upper body surface and a lower body surface, where the body defines a retention slot between the upper and lower body surfaces. Additionally, the tillage point has a fin extending outwardly from the upper body surface in the vertical direction. The fin defines a height in the vertical direction between a base end of the fin positioned adjacent to the upper body surface of the body and a top end of the fin positioned opposite the base end. The fin further defines a lateral width between opposed lateral sides of the fin, where the lateral width of the fin tapers along at least a portion of the vertical height of the fin.
