Abstract: A latch assembly includes a carriage bolt including a threaded shaft having an enlarged head at one end with a non-circular shoulder adjacent the enlarged head. Each latch assembly further includes a thrust washer received about the carriage bolt, a nut threadedly received on the threaded shaft, and a cam lever pivotally attached to the nut. The cam lever pivots about a pivot axis perpendicular to a length of the threaded shaft, the cam lever including a cam surface configured to engage the thrust washer, the cam lever being pivotable from an unlatched position to a latched position such that engagement of the cam surface with the thrust washer during pivotal motion of the cam lever biases the thrust washer toward the enlarged head to thereby latch a mounting flange of a concave grate to a support flange of a support frame.

Abstract: Apparatuses, systems, and method for moving a wing frame of an agricultural head from a folded position to an unfolded position and to articulate the wing frame when in the unfolded configuration using a single actuator are disclosed. In some implementations, an agricultural head may include a center frame; a wing frame coupled to the center frame; a first pivot axis pivotably connecting the wing frame to the center frame, the first pivot axis being configured to facilitate rotation of the wing frame between a folded configuration and an unfolded configuration relative to the center frame; and a second pivot axis, offset from the first pivot axis, pivotably connecting the wing frame and the center frame. The second pivot axis may be configured to facilitate articulation of wing frame, in the unfolded position, relative to the center frame.

Abstract: Apparatuses, systems, and method for moving a wing frame of an agricultural head from a folded position to an unfolded position and to articulate the wing frame when in the unfolded configuration using a single actuator are disclosed. In some implementations, an agricultural head may include a center frame; a wing frame coupled to the center frame; and an intermediate portion disposed between the center frame and the wing frame. The intermediate portion may be pivotably connected to the center frame at a first pivot axis and pivotably connected to the wing frame at a second pivot axis. The first pivot axis may be offset from the second pivot axis.

Abstract: A stalk breaker (134, 134?) for a corn head (104) comprises a bracket (154, 154?) that is configured to be fixed to a corn head frame (106); a first spring (138, 138?) that has an upper end that is coupled to the bracket (154, 154?) and a lower end (166, 166?) that extends downwardly from the bracket (154, 154?); a second spring (140, 140?) that has an upper end that is coupled to the bracket (154, 154?) and a lower end (168, 168?) that extends downwardly from the bracket (154, 154?); and a paddle (136, 136?) that is generally planar and is supported on both of the lower ends of the two springs.

Abstract: An auger conveyor (104) is provided for a row crop harvesting head (100) that has a hinged frame (102). The auger conveyor (104) has a first section (122) that is coupled to a second section (120, 124) with a universal joint (130).

Abstract: A corn head divider lift assist linkage comprises two members and a spring pivotally coupled together, wherein one of the two members is pivotally coupled to a row crop divider and another of the two members is pivotally coupled to a bracket that is fixed at the rear of two adjacent row units.

Abstract: A header height sensor (102) for an agricultural harvester has an elongate sensor arm (112), a reversing joint (114) and a rotary sensor (116) mounted to a bracket (106) that is fixed to a point (100) of a harvesting head. The reversing joint includes a housing (152) that limits the deflection of the sensor in a lateral direction.
