In order to facilitate the test and research on soil resistance in the process of operation of peanut harvesting machinery .This paper developed a peanut harvester soil resistance test device including mechanical part , sensor and in-formation acquisition and processing. The test device is pulled by the tractor , and it can fast measuring soil resistance continuously , real time display test results and immediately memory the results .Calibrate the system and make test on the test device in laboratory , The result of test shows that the system is stable and the average accuracy is 92 .7%.Two fac-tors and three levels of tests in the field , the result of test shows that the test device is stable and accurately reflects the soil resistance .
