PROBLEM TO BE SOLVED: To provide a device capable of readily carrying out the regulation of tilling depth so as to be deeper by upwardly swinging a gauge wheel by one touch operation, and capable of allowing a tiller to travel while lifting tillage tines from the ground surface by downwardly swinging the gauge wheel by the one touch operation. SOLUTION: This device for supporting a front rotary tilling part is characterized in that the gauge wheel 28 is regulated so that the posture may be changed in the nearly vertical direction or the nearly horizontal direction in the front view around an axis center 12 regulated so as to be up in front in the aslant front direction, in a front rotary tiller 7 equipped with a transmission case 1 having an attaching seat 10 for an engine 3 attached thereto in the front and rear direction on the upper surface, and protruding a tillage shaft 2 in the right and left direction of the front lower part, and a wheel shaft 4 in the right and left both sides at the rear lower part, and having tillage tines 15, 15... attached around the tillage shaft 2 in the radial direction, a main tillage cover 8 covering the upper side of the tillage tine 15, and the gauge wheel 28 installed in the front part of the main tillage cover 8.
