ABSTRACT MATHEMATICAL models for the JV1 energy requirements for shearing forage were developed. Experiments were designed and carried out to determine the constants of the models when shearing whole alfalfa and corn stalks without ears. The constants were evaluated by least square methods with the aid of a digital computer. Lack of fit tests showed that the models were statistically adequate. The objective of the optimization was to minimize the shearing energy. The optimization was carried out on a digital computer using the gradient method of descent. Limited experiments were carried out on a full size commercially available forage harvester to substantiate some of the conclusions of this study.
