The varying bulk density of sugarcane causes harvest transport to being either overloaded (resulting in road and vehicle damage) or underloaded (resulting in economic losses). Automatic on-board weighing (AOW) systems measure payloads in real time and present a managerial tool that can reduce the frequency and magnitude of over and underloaded consignments. The benefits and drawbacks associated with the implementation of AOW are presented. Evaluations of current AOW systems for both zone loaded and infield loaded cane are presented and cover accuracy, consistency and factors influencing gross vehicle mass. An economic evaluation of AOW showing attainable return on investment (ROI) for various scenarios, lead distances and increases in average payloads is presented. Practical guidelines to be considered for the successful implementation of AOW are given.
