Want to groom sled trails, freeze skid trails, or set cross-country ski trails? Here is a relatively inexpensive device that has numerous advantages over the conventional chain link fence, bedspring, log, tractor tire, etc. It is easy to construct, manhandle, and store. One of the major advantages over some other methods is that it allows the snow to stay on the trail rather than pushing it to the side. This action allows it to cover rough surfaces such as roots, rocks, and ruts.
