PROBLEM TO BE SOLVED: To provide an industrially produceable device enabling a driver of a traveling car to easily confirm the tilling depth of a rotary operation part of a puddling device at the operation of puddling. SOLUTION: The tilling depth-confirming gage enabling the position of the rotary operation body in the upper and lower direction to be visually confirmed is installed in the front edge part of a rotary cover covering the upper part of the rotary operation body in the puddling and harrow device. The front side of the tilling depth-confirming gage in the traveling direction has a shape retreated rearward from the upper part to the lower part, and the visual confirmation is carried out by a scale displayed by a notched part or a notched hole formed in the body of the tilling depth-confirming gage.
