<;P>;PROBLEM TO BE SOLVED: To provide a traction movement type quantitative supply device for enabling to set the height position of the feed quantitative supply outlet to be higher than the opening port on the upper face side of the hopper of a shredding type combined lap machine B being at a height position of nearly 2 m without causing any trouble during the traction driving operation of a tractor. <;P>;SOLUTION: A box 4 equipped with a floor conveyor 40 is loaded on a floor surface. A second-stage floor conveyor 50 is loaded on a machine (w) which freely travels with the traction of a tractor T, for carrying feed discharged from a discharge port 41 of the box 4 to the quantitative supply outlet (a) on the finishing end side after taking it over to the starting end side in the carrying direction, in such a manner that it is switchable between an approximately horizontal attitude with the carrying direction along the approximately horizontal direction and a sloping attitude of sloping up from the starting end side to the finishing end side in the carrying direction. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
