PROBLEM TO BE SOLVED: To provide a mulching device capable of surely covering the right and left side edge portions of an agricultural film with soil by disposing right and left soil-covering members whose ground-notching depths can separately be adjusted and further disposing specific hydraulic driving members. SOLUTION: In this mulching device, the right and left side edge portions of a rolled agricultural film are treaded with a pair of right and left compacting members 5 on the surface of the ground to deliver the film and cover the surface of the field with the film, and the right and left treaded side edge portions of the agricultural film are then covered with soil by the use of a pair of right and left soil-covering members 6. The ground-notching depths of the right and left side edge portions 6 can separately be adjusted with height-adjusting devices 21, respectively, which can be operated by an operator at hand, and the right and left soil-covering members 6 are provided with hydraulic driving members 21a which are used for hydraulically pressing down the right and left soil- covering members 6 from a state reaching the surface of the ground, thereby adjusting the ground-notching depths of the right and left soil-covering members 6. |
