In the early days of steam, the farm tractors were huge machines, and were often too heavy to work the fields when they were wet. One method of using steam tractors was tried in which two steam powered tractors were set up at either end of a field, and a plow was pulled between them. When the plow reached one tractor, the plow was built to lift one set of plows into the air, so another set of plows would be used on the return trip. This method was used in England and tried in the U.S. but was soon abandoned as being slow and ineffective.
I recently came across your blog and have been reading along. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.
