A product management display system for merchandising product on a shelf includes using a trackless pusher mechanism that travels along a surface on which product is placed. The pusher mechanism of the invention also includes a pusher paddle and a floor that extends forward of the pusher paddle. A flat coiled spring or other biasing element may be operatively connected behind the pusher paddle and extend across the floor of the pusher mechanism and to the front of the shelf. In use, the product to be merchandised may be placed on the coiled spring and on the floor of the pusher mechanism. With this configuration, the pusher paddle is prevented from tipping or bending backwards during operation. The invention may be used with the merchandising of product on horizontal or non-inclined shelves or surfaces, as well as with gravity-fed systems, or systems that use gravity as a mechanism to urge product toward the front of the shelf.
