Abstract: A locking mechanism for an agricultural header includes a rod configured to extend laterally along the agricultural header and a cam coupled to the rod and configured to engage a respective arm of the agricultural header. The arm is configured to support a cutter bar assembly of the agricultural header, and the arm is configured to rotate relative to a frame of the agricultural header. The rod is configured to rotate in a first direction to a first orientation to engage the cam with the arm to block rotation of the arm relative to the frame, and the rod is configured to rotate in a second direction, opposite the first direction, to a second orientation to disengage the cam from the arm to enable rotation of the arm relative to the frame.

Abstract: A reel assembly for an agricultural header includes a reel arm configured to couple to a frame of the agricultural header and configured to support a reel of the reel assembly. The reel assembly further includes a device mounting assembly movably coupled to the reel arm and configured to support a device that is configured to monitor a terrain feature. The device mounting assembly is configured to move between an extended position and a retracted position relative to the frame to move the device between a first position corresponding to the extended position of the device mounting assembly and a second position corresponding to the retracted position of the device mounting assembly. The device mounting assembly is configured to enable the device to monitor the terrain feature at the first position and the second position.

Abstract: A reel assembly for an agricultural header including a reel arm configured to rotatably couple to a frame of the agricultural header and configured to support a reel of the reel assembly. The reel assembly further includes a device mounting assembly coupled to the reel arm and configured to support a device that is configured to monitor a terrain feature. The device mounting assembly is configured to maintain an orientation between the device and a ground on which the agricultural header is positioned as the reel arm rotates relative to the frame of the agricultural header.

Abstract: A header of an agricultural harvester is provided. The header includes a frame having a centerline defining a first side and a second side of the frame. A first portion of either the first side or the second side of the frame has a first trapezoidal profile that includes a first pair of legs that run along a longitudinal axis of the frame and a first pair of bases that form a height of the frame. The first pair of legs include a first top leg and a first bottom leg, and the first bottom leg is angled toward the longitudinal axis.

Abstract: A header of an agricultural harvester is provided. The header includes a rigid modular frame. The rigid modular frame includes a center section, a first outer section, and a second outer section. The first and second outer sections flank the center section and are rigidly coupled to the center section.

Abstract: A transition device for a combine harvester includes a body having an inlet end and an outlet end. A plurality of vanes are positioned on an interior facing surface of the body for guiding crop material through the transition device. Each vane has a first end positioned either on or adjacent the inlet end of the body and a second end positioned either on or adjacent the outlet end of the body. An arc length between the first ends of two adjacent vanes of the plurality of vanes is less than or equal to an arc length between the second ends of the two adjacent vanes of the plurality of vanes, such that the crop material can expand between the two adjacent vanes upon travelling along a trajectory from the inlet end to the outlet end of the transition device.
