The utility model aims at providing a ploughing depth control device of a wheeled tractor, which mainly comprises an electric control system, a hydraulic system and a suspension mechanism. The hydraulic system feeds hydraulic oil to a lifting valve through a hydraulic variable pump; the lifting valve controls a lifting cylinder to operate an agricultural implement to be lifted, declined and positioned in a middle point; and an electric control system receives set signals from a driving cab control panel and real signals from a position sensor and a force sensor through a microcontroller, and controls an electromagnet of the lifting valve according to the deviation value between the set signals and the real signals, so as to realize the lifting and declining of the agricultural implement. Various functions, such as force controlling, position controlling, force and position integrated controlling, transportation active dumping and declining speed controlling, height limiting increasing, rapid declining, agricu
