Abstract

A system for controlling the operation of a harvesting implement includes hydraulically driven implement components positioned on the implement and configured to receive a flow of pressurized hydraulic fluid from a harvester base vehicle. Furthermore, the system includes an implement-based pressure sensor positioned on the implement and configured to generate data indicative of the maximum pressure value of the hydraulically driven components. Moreover, the system includes an implement-based computing system positioned on the implement and communicatively coupled to the implement-based pressure sensor and a vehicle-based computing system positioned on the vehicle. The implement-based computing system is configured to determine the maximum pressure value based on the data generated by the pressure sensor and transmit the maximum pressure value to the vehicle-based computing system.
