PURPOSE:To raise the efficiency of operations by a method in which a plow shaft with a plow claw supported pivotally in a front-raising state along the advancing direction is provided to a shaft in a vertically turnable manner and its inclined angle is adjusted controllably. CONSTITUTION:The support shafts 10 on the left and right sides of a gear case 9 are rotatably fitted into the shaft receivers 11 of the left and right- handed gear case stays 8 of a machine frame 6 connected to a farming implement 4. Drive shafts 14 and 15 pivotally supported on the shafts 10 concentrically are connected through a gear mechanism G to an output shaft 13, and the front end is connected through a shaft coupler 16 to the plow shaft 17 with a plow claw 44 in a front-raising state. The case 9 is made fixable to each turning position by a fixing tool 18, and the rotation power of the input shaft 19 pivotally supported on the upper part of the frame 6 is transmitted selectively to the shaft 14 or 15 by transmission mechanisms 22 and 23 with clutch mechanismsm 20 and 21. According to the slope of farming land and also to plowing depth, the inclined angle of the shaft 17 is adjusted and the soil plowed by the claw 44 is thrown away to the right side all the time. |
