PROBLEM TO BE SOLVED: To provide a ridging device usable for both of early-stage ridging forming a smooth ridge top part, and custom ridging not interfering crops by attaching or detaching a part. SOLUTION: The ridging device has ridger units arranged therein. A right and left pair of the ridger units pulled by a tractor or the like is arranged at a prescribed interval enabling the custom ridging of germinated crops between facing rear ends of neighboring ridging blades, and has early ridging assistant blades to be attached to the facing rear end parts of the pair of the ridger units so as to be freely detachable, and pressing the center top part of the ridge so as to form the smooth surface by being extended from the facing rear ends in the horizontal directions so as to face to each other. The upper or lower, and front or rear position and the angle of a ridging plate at the ridge top part in the assistant blade are preferably changeable by the linking positions of mutual slots of the ridging blades and the assistant blades. More preferably, the extended width is exchangeable by turning the plate to be extended in the horizontal direction. COPYRIGHT: (C)2007,JPO&INPIT
