ABSTRACT:
A spreader (100) for spreading material, which in one embodiment comprises an upper bracket (120), a shaft (140), a return spring (160), a lower bracket (180), first and second sets of chain links (200aand200b), and a spreader plate (220). The upper and lower brackets (120and180) are preferably aligned in the same vertical plane. The first and second chain links (200aand200b) are located on opposite sides of the spreader (100) and on either side of the shaft (140). Upon rotation of the spreader (100) the first and second sets of chain links (200aand200b) experience a centrifugal force sufficient to cause the spreader plate (220) to move down the shaft (140) and upon ceasing rotation the spreader plate (220) returns to a default position proximate to the top of the shaft (140).
