Abstract
A trip mechanism which allows the ground working tool of an implement to pivot about three orthogonal axes. The tool is connected to a shank which is attached to a carriage. The carriage is pivotally connected to the frame of an implement through a ball joint connection. Two arms extend from the carriage on one side of the ball joint and are connected to the frame thereby defining the working position. A hydraulic cylinder provides the necessary force to keep the carriage in its working position and allows deflection of the tool when an obstruction is encountered.
Claims6
A trip mechanism for a ground working tool having a shank connected to said tool, said trip mechanism comprising a forwardly extending carriage rigidly connected to said shank, three point support means between the forward end of said carriage and the frame of an implement, one of said three point support means being a universal pivot connection pivotally connecting the carriage to the frame and two of said three point support means being pin and recess type connection members positioned symmetrically on opposite sides of said universal pivot connection and hydraulic cylinder restraining means having one end universally pivotally connected to said frame vertically spaced from said pivot connection and a second end universally connected to said carriage acting between said carriage and said frame and being operable to allow movement of said ground working tool between an operating untripped position and laterally or upwardly disposed tripped positions.
