ABSTRACT:
A marking element is carried by at least one arm which is pivotally mounted to a short boom. The boom, in turn, is pivotally mounted to the outboard end of a tool bar or planter frame. A single hydraulic ram is used to move the marker between a use position in which the arm extends horizontally so the marker engages the ground, and an upright position in which the arm is folded over the tool bar.
