The search for increasing productivity in agriculture has prompted many proposals for automatic and semi-automatic tractor guidance systems. This project involved the investigation and development of a master-slave tractor guidance system. The guidance system developed, which operated the slave tractor, was composed of a sterring control unit and a speed control unit. Large and small-signal mathematical models indicated that a relatively simple control system would be capable of adequately slaving a tractor-implement unit to an operator controlled unit. An experimental system was constructed and field tested which confirmed this indication.
