PROBLEM TO BE SOLVED: To provide a tilling control system for farming implement, capable of performing in high accuracy a tilling depth automatic control by which the tilling depth of a tilling tine is maintained at an approximately constant level while simplifying the tilling operation of a tiller. SOLUTION: The tilling control system for farming implement is provided, wherein the farming implement is such that a working vehicle travelably supported on front wheels and rear wheels is mounted with a tiller via a link mechanism liftably. This tilling control system includes a lift control actuator functioning to make the tiller ascend/descend, a rear cover sensor for detecting the turning angle of the rear cover of the tiller and a tilling control means for operating the above actuator, wherein the tilling control means works in such a way as to correct a control gain for calculating the tilling depth of the tilling tine of the tiller through at least one or both of the height of the tiller based on the main machine and the height of the tiller based on the ground.
