A system and method for automatically and dynamically controlling a height of a cutting element on a swather or other agricultural machine based on feedback from NIR testing of the cut plant material. An NIR testing system receives and analyzes NIR reflected by the material cut at a particular cut height, and generates an actual value for an RFV or other property of interest. A user interface allows for entering a desired target value. A cut controller compares the actual value and the target value, and adjust (e.g., raises or lowers) a cutting element (by, e.g., changing a pitch of the cutting element) to change the particular cut height if the actual value for the property is different from the target value. If the actual value is substantially similar to the target value, then the cut controller maintains the position of the cutting element.

An agricultural system includes an arm configured to rotate about a pivot joint and to support a portion of a cutter bar assembly, a fluid-filled biasing member slidingly coupled to the arm, an actuator coupled to the fluid-filled biasing member, a fluid pressure sensor configured to measure a fluid pressure in the fluid-filled biasing member, and a controller communicatively coupled to the actuator. The controller is configured to receive an input signal from the fluid pressure sensor indicative of the fluid pressure and to output an output signal to instruct the actuator to adjust a connection point between the fluid-filled biasing member and the arm based on the input signal.

A support system for an agricultural header includes a first actuator configured to couple to a frame of the agricultural header and to a first element of the agricultural header. The support system also includes a second actuator configured to couple to the frame of the agricultural header and to a second element of the agricultural header. Furthermore, the support system includes a third actuator configured to couple to the frame of the agricultural header and to the second element of the agricultural header. The support system also includes a fluid supply system configured to provide pressurized fluid to the first actuator and to the second actuator. The third actuator is fluidly isolated from the fluid supply system, the first actuator, and the second actuator.

The present invention relates to a finger-bar-type mower in which blades reciprocate left and right to mow grass. The mower includes: a connection gear which is power-connected to a driving means of the mower; a reduction gear connected to the connection gear; a shaft rotating according to rotation of the reduction gear; a bridge accommodating and supporting the connection gear and the reduction gear; a blade which is power-connected to the shaft and is reciprocated left and right according to rotation of the shaft, the blade including cutting edges; a guide part supporting the bridge and extending along the blade; and wheels respectively connected to both ends of the guide part, wherein the shaft is disposed in center regions of the blade and the guide part.

An eccentric mount is used to adjust floatation force applied to a cutter bar of a pull type mower when the cut height of the cutter bar is changed. The eccentric mount is rotated to increase or decrease the tension on springs suspending the cutter bar. The eccentric mount is calibrated to adjust incrementally in relation to the position of the skid shoes to provide a floatation force to the cutter bar appropriate to the cutter height as determined by the spring shoe setting.

A header for an agricultural harvester includes: a header frame; a flexible cutterbar carried by the header frame; a plurality of flex arms coupled to the cutterbar; and a flex arm drive assembly coupled to at least one of the flex arms and configured to selectively, linearly displace the at least one coupled flex arm in a vertical direction relative to the header frame.

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

An agricultural vehicle header having a frame having a main truss extending in a lateral direction, at least one support arm extending from the frame in the forward direction, a cutter assembly attached to a respective distal end of each at least one support arm, and a linkage connecting a respective proximal end of each at least one support arm to the frame. The linkage includes a virtual pivot located below the main truss, and at or behind the main truss with respect to the forward direction. An agricultural vehicle having the header is also provided.
