Abstract
A shank mounting assembly for a soil opening point permits adjustment of the spacing between a pair of mounting bolts of the assembly for permitting attachment of the assembly to farm implement shanks having bolt holes of various spacings. The assembly includes an elongated adapter having a hidden, internal cavity to which access is gained only by an elongated slot on the backside of the adapter. The cavity and slot are so dimensioned that while the bolts may move lengthwise within the slot for positioning adjustment, the enlarged heads of the bolts remain in the cavity and cannot pass through the slot. By having the cavity accessible only from the back of the adapter and by providing the front face of the adapter with a smooth, continuous, soil-engaging surface, the heads of the bolts are protectively unexposed to abrasive contact with the soil during use.
