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 electronically linked to one another, being operable in conjunction with one another to exchange information, to maintain a communications link therebetween, and to automatedly coordinate and effect various activities of the harvester and grain transport as a
crop material transfer operation is effected and proceeds.
