发明名称 Bifold field marker
摘要 The present invention is a bifold field marker. The marker utilizes a marking disc mounted on the distal end of an arm. This arm is coupled to a mounting bracket which, in turn, is connected to an implement's tool bar. The arm is articulated at a central knuckle to allow the marker to fold. A hydraulic cylinder is positioned between the mounting bracket and the arm to push or pull the arm about a main pin or hinge. The main pin or hinge on the mounting bracket is oriented at a 45 degree angle in both the horizontal and vertical planes. This allows the hydraulic cylinder to pivot the arm about the 45 degree axis and fold the arm simultaneously until the marker is positioned in a compact orientation along the side of the implement.
