The SNOWSPORT Utility Plow uses a transmission activated design. With the blade in the plowing position, simply drive forward to activate the blade. The push frame allows the blade to slide up and down with the terrain. The rubber cutting edge is designed to cut through the snow but pass over the harder ground surfaces below while being gentle on your grass. Back up and the blade lies back, skimming over the surface. To automatically re-engage the blade for another pass simply drive forward again.
