The invention relates to a control device of a three degree-of-freedom farm tool suspension mechanism of a tractor. The device comprises a controller, a hydraulic cylinder, a displacement sensor builtin the hydraulic cylinder, an angle sensor, a solenoid directional valve, a hydraulic pump, a farm tool position heeling and pitching control algorithm module and the like, wherein the controller isarranged on an instrument desk, and connected with the angle sensor, the built-in displacement sensor, the solenoid directional valve and the hydraulic pump through signal lines respectively; the farmtool position heeling and pitching control algorithm module is used for controlling the farm tool terrain clearance, farm tool heeling angle and farm tool pitching angle. The control device of the three degree-of-freedom farm tool suspension mechanism of the tractor has the advantages that the position, heeling angle and pitching angle of farm tools can be controlled according to the actual farming environment and farming
