Giant Revolving track for a binder bull wheel.
When the grain was ready to be harvested, it had rained so much that it was impossible to move the binder over the soggy soil. It appeared to be either a case of harvesting with hand scythes or losing all the grain. However, the wheel shown solved the problem. It is merely a huge wooden wheel without spokes and wide enough for the bull wheel to travel in smoothly. There is a rim 2 or 3 inches high to keep the bull wheel from slipping out. In use, the bull wheel is jacked up high enough to slip the track under it, and the machine is them ready to travel. This method saved many a crop. Wm. J. Douglass, Missouri Valley, Iowa.
