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 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.

Systems and apparatuses for articulating float arms of a harvester header between a flexible configuration and a rigid configuration are disclosed. The systems and apparatuses include a locking tube that experiences no torque or approximately no torque when the float arms are in the rigid configuration. Further, the systems and apparatuses also avoid adjustments to ensure that float arms are fully retracted, such as into abutting contact with another portion of a header.

A cutter bar skid shoe for a header of an agricultural harvester. The cutter bar skid shoe includes a skid plate having an upper surface, a lower surface, a fore end and an aft end. The cutter bar skid shoe further includes a cutter knife clip integral with and extending forwardly of the fore end of the skid plate for engaging a cutter knife blade.

A piston lock system having first and second cylinders, first and second pistons telescopically connected to the cylinders, and first and second piston locks. The piston locks are movable in a transverse direction within a planar region between the cylinders, between unlocked positions in which the piston locks are not located between the free ends of the cylinders and the free ends of the piston, and locked positions in which the piston locks are located between the free cylinder ends and the free piston ends. A control link is operatively connected to the piston locks, and configured to simultaneously move the piston locks between the locked and unlocked positions.

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.

A method of height control of a machine attachment during operation at different fore-and-aft pitch angles. A height controller receives a first signal magnitude generated by a height sensor disposed on the machine attachment. The first signal magnitude is relative to a first height of the machine attachment disposed at a first pitch angle. The angular degree change is determined when the machine attachment is moved from the first pitch angle to a second pitch angle. A corrected signal magnitude is determined by applying a correction factor to the first signal magnitude. The correction factor is a product of said angular degree change and a scale factor.
