field marker arranged for mounting on an agricultural implement at one side thereof includes a marker arm including a marker disk movable between a deployed position extending outwardly of the implement to one side thereof and a retracted position. The marker arm has an inner arm portion and an outer arm portion both of which are formed from two parallel beams with the disk on the outer end of a rear one of the beams. The inner arm portion is pivotal about a first horizontal axis and is supported on a ground wheel spaced outwardly to allow the marker arm to move upwardly and downwardly relative to the implement. The outer arm portion is mounted on the outer end of the inner arm portion for pivotal movement about a second parallel horizontal axis to allow the marker disk to move upwardly and downwardly relative to outer end of the inner portion which is supported on the wheel and to allow the outer portion to move to a retracted position on top of the inner portion. The whole marker arm is moved by a cylinder about a generally upright axis from the deployed position to the retracted position approximately 90° to the deployed position in which the marker arm trails rearwardly of the mounting member with the marker arm being supported by the ground wheel and free to pivot about the first horizontal axis in the deployed position, the retracted position and as it moves from the deployed position to the retracted position.
