PROBLEM TO BE SOLVED: To provide a contour-plowing device capable of using whole or a part of a plurality of sets of contour-plowing mechanisms by a simple switching operation.;SOLUTION: This contour-plowing device is provided by arranging 2 sets of contour-plowing mechanisms consisting of a plowing claw K mounted on a traveling device such as a sulky tractor, etc., driven and rotated by a rotary driving system of the traveling device for forming a gutter by splashing soil to both sides and also piling the soil in both sides, and a left and right soil-pushing bodies 20, 20 arranged at the rear direction of the plowing claw K, driven by the rotary driving system and being moved/shaken as opening and closing to left and right for compacting the slopes of the piled soil to form a ridge, at a link 30 capable of being lifted up and down at the rear part of the traveling device having a suitable left and right distance, and mounting the both contour-plowing mechanisms U1, U2 with a driven lifting up and down unit SU capable of lowering both of them at at the same time to a contour-plowing position, or lowering one of them at the contour-plowing position and holding another one from the contour-plowing position to an evading position.;COPYRIGHT: (C)2004,JPO
