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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
