ABSTRACT:
A communication device is provided which is intended to aid farm workers in the coordination of harvesting and hauling vehicles in the field during crop harvesting operations. This communication device consists of a transmitter and receiver which are mounted at convenient points within the harvesting vehicle and produce hauling truck respectively. The receiver contains four lighted directional arrows representing directional changes of forwards, backwards, left, and right. The transmitter contains four buttons that correspond in location and function to the directional arrows on the receiver. Thus, when a button on the transmitter is depressed by the harvester operator, the corresponding directional arrow on the receiver will light up signaling the truck driver to make a change in the position of his truck relative to the harvester.
