Abstract
The tool shanks of an agricultural implement such as a cultivator or chisel plow are removably fixed to assemblies which include a holder pivotally connected to the rear side of a mounting member. The mounting member is recessed on its upper side and provided with an overlying clamp arm by which the assembly is affixed to the tool bar of the implement. A tension spring connected between the mounting member and the lower end of the shank holder reacts against swing of the shank holder on its pivotal connection to the mounting member in use of the implement; and the mounting member and shank holder have aligned stops and abutments above and below their pivotal connection which limit the swing of the shank holder.
