The present invention relates to a position variable type ridging, molding, and grading device for securing stable ridge widths by preventing the loss of adjacent ridges as the position of a plow blade can be adjusted in a molding and grading work for forming a ginseng field ridge. Accordingly, the present invention comprises a main body frame (10) in which an upper joint link and a lower joint link (10a, 10b) are formed for the connection with a tractor (1); a plow blade (20) formed in a symmetric shape to form a furrow at both sides of the front lower part of the main body frame (10); a rotary housing (30) formed in the lower part of the main body frame (10) and having a rotary blade (31) for finely breaking down soil of the ridge; and a ridge top (40) formed between plow blades (20) at both sides to flatten the top of the ridge. The main body frame (10) includes a fixation frame (11) integrated with the upper and lower joint links (10a, 10b) and a movement frame (12) to which the plow blade (20) is connected. The fixation frame (11) includes a driving cylinder (50) for moving the movement frame (12) from left to right. The front end of an operation rod (51) of the driving cylinder (50) is connected to the movement frame (12). |
