Abstract：The baling power consumption and efficiency were investigated by torque sensors, data acquisition and computer equipment. The effects of machine settings, material conditions and operating parameters at different levels on baling power and efficiency were discussed. The results show that the power consumption time-domain curve can be divided into three types for green fodder with 3～5 cm cutting length. The first type is characterized by stepwise mutation instantaneous power. The second type is characterized by gentle slope unimodal curve with relatively short baling time,and the third type is characterized by gentle slope multimodal with long baling time. The feeding pressure angle is the biggest affecting factor on baling energy consumption and working efficiency. Choosing alfalfa or corn stalks as baling material almost has no effects on energy consumption and working efficiency. Under the conditions of 15° pressure angle, 60％ moisture content and 1.9 m?s-1 line speed of Chain-crossbar, the machine can consume the lowest energy to achieve the maximum baling efficiency in smooth working process.
