In ptactical work, the density of windrow, the cylinder revolving speed and the speed of the windrow conveyor belt directly affect the picking quality of the baler. This study carried out orthogonal experiments on alfalfe pickup collector's various working parameters to discover the influence of such parameters as the cylinder revolving speed, windrow density and driving speed on the collecting performance and to find the optimum match of parameters. The experiment result indicates that, under different circumstance of fixed forage moisture content, cylinder speed and driving speed, the acceleration of the spring-finger tip increases with a growing windrow density while collection efficiency decreases ending up with a higher energy consumption. Amongst them, the parameters set as below yield the optimum performance: cylinder revolving speed 67 r/min, windrow density 4.0 kg/m, driving speed 3.5 km/h. Under such condition, power consumption and leakage collecting rate reached the relatively minimum value whereas the collecting performance being optimum.
