  • Patent number: 5795108
    Abstract: A method of placing granular materials, such as sand, on a golf course or the like includes loading granular materials into a hopper for feeding a sand gun, directing the granular materials from the hopper into the sand gun, and directing compressed air into the sand gun and into an elongated flexible hose to thereby direct the granular materials into the sand gun through the flexible hose. The sand gun also includes the step of spinning the granular materials therein. The granular materials passing through the flexible hose are directed through an exit nozzle and water may be injected from a water source through the exit nozzle and into the granular materials whereby granular materials and water from remote locations are distributed through a flexible hose onto a predetermined site by aiming the nozzle.
