A folding marker arm for an agricultural implement includes a swing link and a single hydraulic cylinder pivotally connected between the frame and the swing link. A push/pull link is mounted between the swing link and the marker arm. As the cylinder extends to rotate said marker toward the storage position and the marker arm passes through top dead center the design decelerates the marker arm as it approaches the storage position to avoid having the marker arm slam into the frame.
