Abstract: A system, and method of use thereof, for enabling short range intercommunication and the exchange of logistical information between and among a plurality of authorized agricultural machines that are designed to be operable in conjunction with one another to effect, as a specific identified group, a given agricultural operation, including a plurality of individual agricultural machines each of which has a communications control portion operable to transmit and receive short distance communications signals and each of which also has authentication credentials associated therewith establishing such machine's entitlement to share in the logistical information and to be considered and treated as a member of the specific identified group involved in the performance of the given agricultural operation, with such individual agricultural machines, when positioned in range of the short distance communications signals of the individual agricultural machines, forming a peer-to-peer network in which such individual agricu

Abstract: A system and method for enabling the communication to and establishment among a plurality of generally like and like-purpose agricultural machines designed to perform generally similar agricultural operations within a given area generally like performance parameters, especially based upon the performance parameters of a particular agricultural machine that is considered or deemed to be the expert or exemplar machine, which system and method employ short range communications systems included in or associated with the operating systems of the individual agricultural machines to effect the distribution of the exemplar performance parameters to the plurality of agricultural machines, through a peer-to-peer wireless network between and among the plurality of agricultural machines for point-to-point communications, for use by the individual agricultural machines in controlling and performing the agricultural operation.

Abstract: A system, and method of use thereof, that employs short distance communications signals, thereby limiting and localizing the dissemination area for such signals, for interactively coordinating crop material transfer operations between a harvester and a grain transport, including the automated conduct of an unloading operation, including commencement of the actual unloading of the grain through continuation of such unloading to termination of such unloading, which system and method of the present invention employs operating systems in the harvester and grain transport that so operate to become electronically linked to one another to thereafter operate in unison with one another to effect and control the conduct of the crop material transfer operation between the harvester and grain transport, with each of such operating systems having associated therewith a short range communications system for the transmission and receipt at close range of electronic data signals, such operating systems, when appropriately el

Abstract: A forage harvester is provided with a rotatable cutterhead (9), a solid cylindrical grinding stone (15), a motor (33) for moving the stone (15) along a path adjacent the cutterhead (9) and an adjustment mechanism for moving the stone (15) towards the cutterhead (9). During the final stage of the sharpening cycle the stone (15) is automatically moved along the path at a substantially lower speed in order to improve the finishing of the cutterhead (9), such that the shearbar (11) can be adjusted closer to the rotating cutterhead (9).

Abstract: The disclosure relates to an apparatus for controlling the position of a header relative to the ground surface, the apparatus including one or more pivotable shoes arranged to contact the ground and to move in dependence on changes in the ground contour. A further member secured to such a pivotable shoe includes a reflecting surface remote from the point of contact of the shoe with the ground surface. An emitter/receiver is spaced from the reflecting surface and connected to a control circuit whereby the position of the header relative to the ground may be measured by virtue of the position of the reflecting surface. The position of the header relative to the ground surface is then adjustable in dependence on the detected measurements, by means of various actuators associated with the apparatus.

Abstract: A method for moving a shearbar (102) towards a fixed stop (109), wherein the method comprises the steps of; energizing a bidirectional motor (110/112) for driving a guide screw (106/108) to move the shearbar towards the fixed stop (109), monitoring a variable indicative of the torque or force output of the motor (110/112), limiting the torque or force output to a first maximum value, moving the shearbar (102) against the fixed stop (109) and stalling the motor (110/112) thereby, deenergizing the motor (110/112), when the resulting torque or force output reaches or exceeds the first maximum value; and energizing the motor (110/112) for moving the shearbar (102) in the opposite direction, away from the stop (109), while not limiting the torque or force output or while limiting the same to a second maximum value, which is substantially larger than the first maximum value.
