ABSTRACT:
The invention comprises a hydraulic press for attachment to one of a plurality of shanks of an earth working implement. The press has a lateral base with a pair of spaced notches which form channels for the shank to be positioned in when the press is attached to the shank. A hydraulic cylinder has one end pivotally mounted to the frame of the press and its other end hydraulically actuates a piston which upon actuation telescopes the piston toward the shank intermediately between the spaced notches to engage the shank between the spaced notches, with the notches restraining outer portions of the shank against movement with the piston as it moves, while the piston moves against the intermediate portion and moves the intermediate portion thereby bending the shank. The press has a configuration to fit between the shanks of the implement when attached to the implement and said piston is adjustable on the frame so that when the press is attached to the shank the shank may remain mounted to the implement and an earth working tool may remain mounted to the shank while bending the shank at various locations along its length.
