Abstract
Abstract A seed boot for pneumatic seeder or fertilizer assemblies includes a seed or fertilizer tube having an attaching bolt extending therethrough adjacent the base thereof and just above the splitting or separating saddle. A forwardly extending crease is formed within the rear of the tube and extends into the tube above the bolt thus dividing the seed and/or fertilizer into two equal streams which clear the bolt and then engage the saddle well down the sides thereof so that the seed and/or fertilizer is deflected outwardly under the wings of the sweep thus reducing the possibility of the seed and/or fertilizer from bouncing up into loose soil and therefore being wasted.
