The present invention provides a folding row marker assembly for use with an agricultural implement. The folding row marker assembly has an inner link assembly with at least one inner link member and a mounting adapted to attach to the agricultural implement. The folding row marker assembly further comprises a plurality of first arm members that hingedly connect to both the first link assembly and an outer link assembly having at least one outer link member. In one embodiment, the folding row marker assembly has two sections, where the second section is an outer arm member that hingedly connects to the outer link assembly and connects to a marker preferably through a shear bolt. In an alternative three-section embodiment of the folding row marker, the outer link assembly further comprises a plurality of outer link members that combine to add a middle section containing a middle link assembly that connects to the inner arm members, an outboard link assembly that connects to the outer arm member, and a plurality of middle arm members that connect the middle link assembly to the outboard link assembly. In both embodiments, a radial motion of the inner arm members around the inner link assembly causes the outer arm member to move in a controlled radial motion around the outer link assembly, relative to the inner arm members. The radial motion of the inner arm members around the inner link assembly is caused by an actuating mechanism, such as a hydraulic cylinder, that connects to an inner link member and to one of the inner arm members. As a result, the folding row marker assembly moves between a folded storage position and an extended, generally horizontal use position in which the marker engages the ground.
