The Tumblewheel enables you to quickly and easily roll a fence line to a new position.The Tumblewheel's unique center hub maintains power while the fence is being moved. It can be used on flat very hard and frozen ground. The legs remain live except for two legs that are on the ground. Where several breaks are needed in one paddock, Tumblewheels are ideal for quick and efficient rationing of grass. This fence consists of a number of electrified 'wheels' spaced across the pasture. The wheels are held upright with the tension of the single line fence which passes through the center. When one or both ends of the fence is moved, the wheels roll along. When you stop, the fence stops.
