PROBLEM TO BE SOLVED: To provide a spreader capable of quantitatively spreading clods, granular soil improving materials or aggregates at a fixed thickness and at a fixed width via machine execution on an execution surface for flying sand prevention or soil improvement. SOLUTION: This quantitative spreader 4 is fitted to the rear section of a crawler dump track and spreads clods, soil improving materials or aggregates at a width corresponding to the vehicle width. The quantitative spreader 4 is constituted of an auxiliary roller 7 or a belt conveyor for delivering loaded objects such as clods, soil improving materials or aggregates to the rear and a spreading mechanism for quantitatively spreading the delivered clods, soil improving materials or aggregates.
