PROBLEM TO BE SOLVED: To plow deeply from the inside of the ridge side in a field to form a pretty ridge by sufficiently forming a groove at the ridge side. SOLUTION: This ridge side plow-treating unit is provided by installing plowing units 15, 15 at the left and right both sides of a plowing transmission case 11, constituted such that one of the plowing units 15, 15 as a large diameter and another as a small diameter and arranging a soil-removing board 18 at the rear direction of the large diameter plowing unit 15 for performing the plowing with the large diameter plowing unit 15 along the ridge side. Thus, it is possible to plow the ridge side more deeply as compared with its inside and while forming a deep groove at the ridge side by the soil-removing board, forming a ridge by sufficiently piling soil.
