Abstract: With the advantage of small size ,the micro‐tiller has mainly been used for farming in mountain‐ous and hilly areas .However ,mainly relying on manual operation and the function of actuator for adjust‐ment on the plowing depth ,most of existing tillers have problems in maintaining stability and consistency of the depths while farming .An automatic control system ,which is mainly for accurately and stably adjus‐ting the depths in the plowing situation ,has been presented in this paper .The system consists of 3 parts , including detectors ,control units and actuators .Detectors achieve the real‐time monitoring with potenti‐ometers ,and the data from detectors would be analyzed by the control units ,in order to figure out the plo‐wing depth as the real‐time value .By comparing with the real‐time value and the ideal one ,consequent logical operation would take place in control units .Then certain orders would be sent to the actuator for the adjustment on the plowing depth .
