Abstract
A trip mechanism for a ground working tool connected to a frame. The frame is connected to a carriage using a three point connection. A pivotal member is provided in the frame and a tension member is connected between one arm of the pivotal member and the carriage. Compression springs are provided to act between a second arm and the frame. An obstruction exerting a predetermined amount of force on the ground working tool of the implement will allow the trip mechanism to be activated thus preventing damage to the tool. An adjustable stop is provided on the frame engaging the first arm when the apparatus is in its untripped position to adjust the untripped position of the second arm relative to the frame to vary the initial force required to trip the mechanism.
