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.

A predictive map is obtained by an agricultural system. The predictive map maps characteristic values at different geographic locations in a field. A geographic position sensor detects a geographic location of an agricultural harvester at the field. A control system generates a control signal to control a reel subsystem of the agricultural harvester based on the geographic location of the agricultural harvester and the predictive map.

A harvesting assembly for harvesting a crop includes a frame, a cutting knife configured to cut crop, a feed drum, a draper assembly, a first auger assembly, and a second auger assembly. The draper assembly and the auger assemblies are configured to move the cut crop toward the feed drum. The auger assemblies each include a first auger, a second auger, and a mounting unit coupled to the frame and coupled between the first auger and the second auger to support the first auger and the second auger during rotation of the augers.

A system and method for performing cutting operations with an agricultural implement includes a cutting member capable of cutting plant material supported on the agricultural implement. A vibration source is operatively coupled to the cutting member. The vibration source is configured to generate a vibrational output at an ultrasonic frequency which is transmitted to the cutting member. The vibrational output is propagated through at least a portion of the cutting member to vibrate the cutting member as the plant material is being severed during the performance of the cutting operation.

A header of a harvester includes a cutter bar assembly, a side deck, and an airbag. The side deck includes a conveyor and an arm assembly. The cutter bar assembly is configured to cut crops, and the conveyor is configured to transport the crops cut by the cutter bar assembly toward a center of the header. The arm assembly is coupled to the cutter bar assembly and to the at least one airbag. The arm assembly is configured to pivot to enable the cutter bar assembly to flex along a lateral axis of the header. The airbag is configured to apply a substantially constant force to the at least one arm assembly.

An agricultural header includes: a main section including a main frame carrying at least one cutting element; at least one wing section pivotably coupled to the main section and including a wing frame; and a linkage pivotably coupling the at least one wing section to the main section, the linkage including an upper bar and a lower bar which are both coupled to the main frame and the wing frame, the upper bar defining an upper bar axis and the lower bar defining a lower bar axis which is non-parallel to the upper bar axis.

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.
