Yield mapping is necessary for precision farming. An on-site rice weighting system for a head-feed combine was developed to measure the total weight of rice grain harvested while the combine was operated. A load cell system was used to monitor rice weights accumulated into the combine grain tank using a load cell. This method gave cumulative grain weight readings as a function of time. The system consisted of a load cell, tow supporting brackets, and a computer-based data acquisition system.
