乌兹别克斯坦特别重视发展畜牧业、家禽业和渔业。在动物的日粮中，由玉米、苜蓿等饲料作物的绿色秸秆切割而成的绿色饲料占有特殊的地位。为了高质量地切碎秸秆，满足每种动物所需的切割长度，开发了一种设计简单的切碎绿色饲料的切碎机。在2800 rpm的发动机速度、950 rpm的切割滚筒转速和10 rpm和20 rpm的进料辊两次旋转下进行切碎机工作的测试，苜蓿秸秆的平均长度为71.6 cm，玉米秸秆的平均长度为216.4 cm，示出了在10rpm的进料辊旋转速度下秸秆的平均切割长度为10.6mm，从数据中可以看出，进给辊速度增加2倍，切割长度增加1.66倍，这证实了所得到的理论假设。
In Uzbekistan, special attention is paid to the development of livestock, poultry, and fish farming. In the ration of animals, green fodder obtained by cutting green stalks corn, alfalfa and other feed crops have a special place. For high-quality chopping of stalks with the required cutting length for each type of animal, a chopper has been developed with a simple design for chopping green feed. Testing of the chopper work, carried out at an engine speed of 2800 rpm, a cutting drum rotation speed of 950 rpm and in two rotations of the feed rollers 10 rpm and 20 rpm with an average length of alfalfa stalks 71.6 cm and an average length of corn stalks 216.4 cm, showed that at a feed roller rotation speed of 10 rpm the average cutting length of the stalks was 10.6 mm, and at a feed roller rotation speed of 20 rpm - 17.6 mm. It can be seen from the data that with a twice increase in the feed roll speed, the cutting length increases 1.66 times, which confirms the theoretical assumptions obtained.
