A system and method for producing a bale having a target weight set by a user. A processor compares stored actual weights to the target weight, and, based on a difference, adjusts the bale-forming process. The processor may calculate a load value for a connecting rod, measure an actual load value for the rod, and, based on a difference, set a new pressure value for the process, and then repeat these steps until the bale is fully formed. The processor may determine a first line relating a calculated load on the connecting rod to a current pressure, determine a second line relating a measured load on the rod to the current pressure, identify a pressure value at the intersection of the first and the second lines, and make this the new pressure value for the process, and then repeat these steps until the bale is fully formed.
