PROBLEM TO BE SOLVED: To provide a tilling depth control structure of a tillage work machine, which can prevent the generation of an engine stall caused by the overload of an engine without using the revolution of the engine as an index for preventing the engine stall.
SOLUTION: This tilling depth control structure of the tillage work machine is characterized by having a driving means 41 for lifting or lowering a rotary tiller 3 on the basis of a travel vehicle body 1 having an engine 6 loaded thereon, a setting means 56 for setting a control target tilling depth of the rotary tiller 3, a detection means 53 for detecting the tilling depth of the rotary tiller 3, a control means 25A for controlling the operation of the driving means 41 so that the output of the detection means 53 may correspond to the output of the setting means 56, and a calculation means 62 for calculating the fuel injection quantity of the engine 6, wherein the control means 25A corrects the control target tillage depth on the shallow side on the basis of a threshold and the output of the calculation means 62 when the output of the calculation means 62 exceeds the threshold for preventing engine stall, and controls the operation of the driving means 41 so that the output of the detection means 53 may correspond to the control target tillage depth after the correction.
