ABSTRACT:
A folding row marker includes first, inner and second, intermediate sections pivotally coupled together, as well as a third, outer section pivotally coupled to a distal end of the second section. A marker disc is disposed on the distal end of the third section and a hydraulic ram pivotally displaces the second section relative to the first section and further, via connecting linkage, pivotally displaces the third section relative to the second section during extension of the row marker to the use position and retraction of the row marker to the stored position. The first section is adapted for pivoting attachment to an end of a folding toolbar and linkage is provided to maintain all sections of the row marker under application of a positive force in a fixed, fully folded, compact and stable configuration when the toolbar is in the stored position.
