ABSTRACT:
A method and system are disclosed for moving and placing in hard to reach locations granular and other particulate material such as sand, gravel, earth and similar materials. The system includes an improved augar for moving the material and an improved rotary airlock mechanism designed to withstand the abrasive action of the particulate material and at the same time move the material several hundred feet through a flexible conduit for placement in a pre-designated location. A system and apparatus is also disclosed for transporting on one vehicle all of the devices needed at a remote site for operation the particulate placement system, including a front loader.
