Abstract: A dirt distribution device for attachment to the outboard end of an earth moving blade of a grader machine includes a motor driven rotary dirt slinger carried on a platform that is pivotally carried on a support arm that, in turn, pivots on the clamp unit that mounts the device to the blade. The device serves to sling dirt scraped up by the moving blade over areas inaccessible to the blade, e.g., around the base of trees planted in rows adjacent ditches that require periodic reconditioning by scrapping using grader machines. The device basically includes a turnbuckle or equivalent unit to adjust the radial angle of the support arm relative to the blade and a similar unit to adjust the radial angle of the platform relative to the support arm, but may include further adjustment units to add additional tilt modes to the platform.
