Abstract
A marker assembly for use with an agricultural implement includes a float linkage that allows limited vertical displacement of the marker assembly when the marker assembly is in a fully deployed position. This limited vertical displacement accommodates changes in surface terrain (contour) as well as in-field obstructions. The marker assembly is comprised of a series of interconnected linkages. The linkages are extended by an actuator, e.g., hydraulic cylinder and ram. The float linkage allows for vertical displacement of the extended linkages even when the actuator is in an extended position.
