PROBLEM TO BE SOLVED: To provide a tillage controller of a farm implement, which can simplify the tillage works of the tiller, and can highly accurately perform an automatic tillage depth control for approximately constantly maintaining the tillage depth of tillage tines. SOLUTION: This tillage controller of the farm implement which is liftably mounted on a working vehicle travelably supported on front wheels and rear wheels through a link mechanism and has a lift control actuator for lifting or lowering the tiller, a tillage depth sensor for detecting the tillage depth of the tillage tines of the tiller, and a tillage control means for operating the lift control actuator is characterized by disposing a control gain dial for steplessly changing the control gain of the tillage control means for calculating the tillage depth of the tillage tines and controlling the tillage control means with a changed control gain to change the control gain on the basis of the control gain dial to match the tillage depth of the tillage tines with a set tillage depth.
