The object was to obtain the forces of soil on compacting ridge device of ridger when operating. Taking 1DSZ-350 type hanging unilateral rotary tillage compacting ridger for paddy field as research carrier, a kinetic parameters measurement system was designed for compacting ridge device using strain sensor, and a kinetic test bench was set up. The operation parameters of compacting ridge device were measured, and the variation rules of the force of soil on pinnae, and the relationships between ridge compaction and forward speed and rotation speed of compacting ridge device were obtained, which was carried out through single factor experiment with the forward speed and rotation speed of compacting ridge device as experiment factors, the force of soil on pinnae and the compaction of ridge in the process of building ridge as experiment indicators. The results showed that when the rotation speed of compacting ridge device was fixed , with the increase of forward speed of machinery, the average value of force of soil on pinnae was increased, and the compaction of ridge was decreased, which was in the range of 2838.1~5695.2N and 2250~1680kPa, respectively. When the forward speed of machinery was fixed, the average value of force of soil on pinnae and the compaction of ridge were increased with the increase of rotation speed of compacting ridge device, which was in the range of 3203.8~5990.3N and 1460~2180kPa, respectively. According to the test results, the test system for operation parameters of compacting ridge device can meet the requirements, which can provide important reference for the relevant parameters test of similar device.
