Abstract: A simulated green comprises a plurality of panels positioned in coplanar relation next-adjacent each other to form a continuous surface inclined at a predetermined angle with a horizontal base. Each of the panels has spaced opposite parallel first and second edges. A mounting device pivotally mounts each of the panels on the base at the first edge of each of the panels whereby each panel is pivotally movable about its first edge from a closed position in which it is substantially coplanar with the other panels to an open position in which its second edge is raised above and spaced from the first edge of the next-succeeding panel sufficiently to permit the passage of a golf ball between next-adjacent panels. A control device mounted on the base is coupled to each of the panels for selectively moving the panels in unison to their closed and open positions.
