- 21 - SHANK SHAPER ABSTRACT OF THE DISCLOSURE Arcuately curved cultivator shanks carrying ground working tools often become partially straightened or the at- taching portion becomes bent due to the ground working tool engaging obstructions such as a root, rock or the like. Due to the resiliency thereof, they are difficult to re-shape to the original contours or specifications. The present device includes firstly, a vertical standard having a cross pin at the upper end thereof under which the hooked attaching end may be engaged. The distal end, which is apertured to re- ceive the ground working tool, is engaged by a jack under- neath the standard and a sliding member engages within the standard and is engaged by the distal end of the shank so that when the jack is extended, the arcuately curved por- tion is re-shaped to the original contours. Secondly, the attaching portion of the shank which may have become dis- torted or bent due to the shaping of the arcuately curved portion, may be engaged between a pair of spaced apart horizontally situated cross pins between a pair of horizon- tal members. The jack is then engaged with the attaching portion between the cross pins and is extended thereby straightening the attaching portion.
