ABSTRACT OF THE DISCLOSURE A field marker for attachment to a sprayer boom has an outer square tube clamped to the end of the spray boom. An inner square tube slides in the outer tube and is connected to it by a pair of coil springs that bias the inner tube downwardly. An hydraulic cylinder joins the inner and outer tubes as well and, when actuated, raises the inner tube against the biasing force of the springs. A marking disk is mounted on the bottom end of the inner tube, preferably with an adjustable mounting to accommodate booms of different heights.
