Systems and methods for automatically configuring a cutterbar between a flexible configuration and a rigid configuration in response to actuation of a gauge wheel are disclosed. The cutterbar is coupled to the gauge wheel such that extension of the gauge wheel causes the cutterbar to move into the rigid configuration and retraction of the gauge wheel causes the cutterbar to move into the flexible configuration.

A universal crop head assembly is carried at the front of and by a harvester. The new crop head assembly includes a frame assembly, an intermediate multi-crop reel assembly carried by the frame assembly and having selectively extendable and retractable fingers for small grain harvesting. A lower cutter bar assembly is carried by the frame assembly and for cutting grain stalks. An upper forward cutter bar assembly is carried by the frame assembly and supports an upper cutter bar for cutting corn stalks about an upper end, an adjustable air knife assembly for blowing against severed corn stalks upper ends; and a lower draper belt assembly carried by the frame assembly and for moving grain cut by the lower cutter bar assembly.

A sugarcane harvester includes a basecutter assembly for cutting sugarcane stalks from sugarcane plants; a chopping section for receiving the sugarcane stalks from the intake and cutting assembly and chopping the sugarcane stalks into billets; a discharge assembly for receiving the billets from the chopping section and discharging the billets to a storage vehicle; and a height adjustment system for automatically adjusting a height of the basecutter to avoid unwanted contact between the basecutter and a ground surface.

A flexible header for an agricultural vehicle including a frame, at least one cutter bar movably coupled to the frame, and an adjustment system coupled to the frame and the at least one cutter bar. The adjustment system is configured to adjust a position of the at least one cutter bar. The adjustment system includes at least one linkage assembly. The linkage assembly includes a first link member and a second link member. Each of the first and second link members are rotationally coupled to the frame. The adjustment system also includes at least one fluid spring coupled to the first link member and the second link member such that the at least one linkage assembly translates a substantially linear movement of the at least one fluid spring to adjust the at least one cutter bar.

The present invention provides an autonomous traveling work machine that can accurately receive positioning signals from navigation satellites and autonomously travel without deviating from a traveling path, even in the case of an inclined slope. The autonomous traveling work machine includes a traveling machine body, a positioning receiver that receives positioning signals from navigation satellites, an autonomous traveling control device that performs control for autonomous traveling along traveling paths based on the positioning signals, an inclination detection unit that detects the inclination of the traveling machine body and outputs inclination angle information, an inclination angle determination unit that determines an inclination angle based on the inclination angle information, and a rotation control mechanism that rotates the positioning receiver with one or more degrees of freedom. The rotation control mechanism keeps the positioning receiver horizontal based on the inclination angle.
