Abstract
An Improved Apparatus and Method for Moving and Placing Granulate is disclosed. The disclosed device is a portable, self-contained apparatus capable of discharging granulate into hard-to-reach areas, as well as providing assistance in covering vast open areas with granulate in a short time. Furthermore, the device and method described herein permit the application of granulate into areas that are normally inaccessible and would require many hours of human labor, and thereby potentially avoiding damage to the site that might be incurred if employing a prior method and device. Still further, the present invention serves to provide discharge of granulate near or adjacent to retaining walls and underneath concrete flatwork
