ABSTRACT:
An improved double disk blade opener assembly and disk blade therefor are provided for a grain drill or the like. A pair of bearings are supported on opposite sides of a seed boot casting or arm structure mounted on the implement. Each bearing supports a threaded shaft which extends outwardly therefrom to a blade-receiving end. A pair of generally flat disk blades each fabricated from a single piece of sheet metal and having opposed outwardly cupped central portions to accommodate the bearings are secured on and rotate with the shafts. Mounting the bearings in the boot rather than in bearing caps on the blade decreases the overall width of the opener and increases trash flow between adjacent openers. Socket screws which previously were used to secure the blade assembly to the boot, which required tapping of the boot and which frequently worked loose therefrom are eliminated. The specially shaped disk blades retain the desired furrow cutting characteristics of conventional flat disk blades.
