Vachowski, Brian ; Maier, Neal . 1998. Off-Highway Trail and Road Grading Equipment. 9823 2837. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center.
Describes light-duty grading equipment that can be pulled by an all-terrain vehicle to maintain wide trails and roads. Three pieces of equipment were tested on a sandy motor-cycle trail and a trailhead access road in the Francis Marion National Forest in South Carolina: a modified trail rock rake, a trail drag, and a commercial product, the Ultra Light Terrain Grader. All three pieces of equipment removed the washboarded "whoop-de-doos" in the sandy soil. Narrower equipment would have worked better on trails. The equipment worked very well on roads and offers an affordable alternative to heavier graders for light-duty use. Other trail-grading accessories and drags for small tractors are also described.
