ABSTRACT:
A system and method for operating a ground working tool having attached thereto an implement includes a trip mechanism. The trip mechanism includes a generally horizontally oriented hydraulic cylinder configured to be biased into an extended position to engage the implement in a work position engaged to work the ground. Specifically, a link rod connects the hydraulic cylinder to a carrier to which the implement is attached. The link rod can be adjusted in length and has a generally small diameter, such that, upon extending into hydraulic cylinder when the implement impacts an obstruction, the link rod does not contact the hydraulic cylinder.
