An agricultural mowing assembly that includes an agricultural vehicle and at least one mowing device connected to the agricultural vehicle. The at least one mowing device includes a frame and a cutter bar movably connected to the frame. The cutter bar is configured for mowing a crop material in a field. The agricultural mowing assembly also includes a cut quality detection system that includes a plurality of sensors connected to the frame and configured for sensing color variations on the field and a controller operably connected to the plurality of sensors and receiving the sensed color variations on the field from the plurality of sensors. The controller is configured for determining a cut quality of the cutter bar based upon the sensed color variations on the field.

A sickle cutting apparatus having a plurality of knife guards and a sickle bar having a plurality of sickle knife blades driven for reciprocating movement relative to the knife guards. The length of the cutting edge of each knife blade from a transverse rearmost cutting line at which a cutting action occurs is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.2 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.

A cutting system for a harvesting header includes a transversely extending cutter bar, a transversely extending knife back, a knife section mounted to the knife back having a knife edge extending generally in a forward direction, a knife guard component having a front guard portion and a rear portion interconnected by a medial portion having a recess. The medial portion is configured for receiving a lengthwise portion of the knife back with the knife section being received into, and the knife section is operable to move transversely into and out of a cutting slot in the front guard portion. A hold down component is located between an upper surface of the rear portion of the knife guard component and an underneath surface of the cutter bar, and an attachment mechanism is operable to secure the knife guard component and the hold down component to the underneath surface of the cutter bar.

An arm assembly of an agricultural header includes a leaf spring configured to couple to a frame of the agricultural header. The arm assembly also includes an arm coupled to the leaf spring, in which the arm is configured to support a cutter bar assembly of the agricultural header. In addition, the arm assembly includes an actuator coupled to the arm and configured to couple to the frame of the agricultural header. The actuator is configured to urge the arm to move the cutter bar assembly upwardly relative to a soil surface, and the arm assembly is configured to be coupled to the frame only by the leaf spring and the actuator.

An improved knife assembly for use with a header of an agricultural harvester. The assembly includes a knife head, a knife back and a plurality of sickle sections fastened to the knife head and knife back. The sickle sections include first and second portions where a second portion of one knife section overlaps a first portion of an another sickle section when the knife sections are arranged in adjacent relationship. The overlapping areas of the adjacent knife sections include aligned though holes which shared fasteners. The resultant construction reduces the overall knife assembly mass thereby leading to increased cutting speeds and corresponding harvester ground speeds. Additionally, the time and labor associated with manufacture and maintenance is reduced while the assembly strength and force distribution capability is enhanced.

The feeder device located at the centre section of a front of a harvester. The feeder device comprises one or more flights configured for improving operation of the feeder device. The feeder device comprises a shaft including a plurality of flights. They extend substantially along the entire length of the shaft and are arranged in a spaced apart relationship with respect to each other. In this manner, a threaded-like formation defined by the spaced apart arrangement of flights extends substantially along the entire length of the shaft of the feeder device.
