Abstract:
A spreader extension and gravity discharge box in combination, comprising a gravity discharge box having a floor, a rearward edge of said floor, a forward end wall, a first side wall, an opposite second side wall, and an open rearward end wall having a tailgate pivotally mounted for pivotal movement between an open position and a closed position, said tailgate having a lower edge, said lower edge being adjacent said floor and in closing relationship with said rearward end wall when said tailgate is pivoted to its said closed position, said lower edge being pivoted outwardly from said rearward end wall and upwardly from said floor when said tailgate is pivoted toward its said open position, said forward end of said discharge box being liftable to an unloading position to slide contents thereof out through said open rearward end wall when said tailgate is pivoted toward said open position, spreader extension means for extending the surface area over which said contents slide after passing through said open rearward end wall located adjacent said rearward edge of said floor of said gravity box, wherein said spreader extension means includes a laterally extending member having a planar upwardly facing sliding surface substantially co-planar with said floor of said gravity box, wherein said laterally extending member adjacent said rearward edge of said floor of said gravity box is mounted for rotation between a first position wherein it extends rearwardly from and substantially co-planar with said floor of said gravity box and a second position wherein it extends downwardly relative to said floor of said gravity box.
