  • Patent number: 10772252
    Abstract: A tillage implement having a frame member extending in a fore-aft direction of the implement, the frame member pivotally connected in a foldable configuration, the frame member comprising a main frame section; a first wing section and a second wing section, each being pivotally connected at opposing lateral sides of the main frame section in the fore-aft direction; and a middle breaker including a first disc coupled to the main frame section, the first disc laterally offset from a centerline of the middle breaker extending in the fore-aft direction, the first disc having a concave side facing towards the centerline, and a second disc coupled to the main frame section, laterally offset from the centerline of the middle breaker, the second disc having a concave side facing towards the centerline.

  • Patent number: 8544557
    Abstract: A pivot limiting device for an agricultural implement is disclosed. The agricultural implement includes a first frame section pivotally coupled to second frame section at a pivot location. The device includes a compression structure having a spring compressed to a preset load. The compression structure is coupled to the first frame section. A plunger includes a first portion positioned adjacent the second frame section and a second portion positioned adjacent the compression structure to move relative thereto between a first position placing no additional compression on the spring when the second frame section pivots in a first direction and contacts the plunger with a first force less than or equal to the preset load, and a second position further compressing the spring when the second frame section pivots in the first direction and contacts the plunger with a second force greater than the preset load.
