A steam plow is a plow powered by steam power. He was born in the middle of the 19th century. Invented in the 19th century and was a first step in the mechanization of soil cultivation in agriculture, which had previously been done exclusively with animal or human muscle power could be carried out. A working steam plow set usually consisted of two self-propelled locomotives, called steam plow locomotives, which were equipped with a cable winch that was initially arranged vertically and later only horizontally under the steam boiler; furthermore the associated tipping plow, a crew car, two water trucks and a crew consisting of up to twelve men. During steam plowing, the plow was pulled over the field using cable winches between the locomotives that provided the forward movement at the edge of the field. The plow locomotives themselves only moved along the paths at the edge of the field, the so-called headlands. Initially there were two men on the plow, a driver and an assistant to insert and tilt the plow. In addition to the tipping plows, there were other tillage devices for use with the steam plow sets, especially cultivators. These were not tilted to change the working direction, but had a device that turned the cultivator when the direction of pull of the rope changed. The English engineer John Fowler developed the so-called Two-machine system in which one locomotive drives at each edge of the field. Each machine took turns pulling the tipping plow across the field with its winch. It was only through this development that the steam plow began its triumphal march throughout the world. The rope winding device, which enabled the horizontal installation of the winch, was developed by Max Eyth, among other inventions relating to steam plow technology. At the beginning of steam plowing, there were also single-machine systems that made do with a single, initially not even self-propelled steam locomotive and used deflection rollers and so-called anchor cars instead of the second machine. To do this, however, the locomotive had to be equipped with two winches. Plowing took place as follows: The machine, on whose edge of the field the plow was located, signaled its readiness with a whistle from the steam whistle. The other machine then drove a little further forward and began to pull the plow across the field. The rope of the first machine remained connected to the plow - decoupled from the drive - so the rope was unwound and pulled together with the plow to the other edge of the field. Once there, the operator of the pulling machine stopped the cable and the plow was tilted in the other direction for plowing. The design of the tipping plow made turning the plow unnecessary. The process then began again, this time in the opposite direction. Locomotive, fueled, with crew The capital-intensive sets of machines in West Germany were usually not owned by farmers, but were operated by independent entrepreneurs or cooperatives who carried out the plowing on behalf of them. The farmers had to provide certain services of their own, e.g. B. to provide the water and coal necessary for the operation of the steam engines. On East German estates, e.g. B. in Pomerania or East Prussia, there were also companies that had their own steam plow sets in operation. Plowing process A complete steam plow set with two machines and a five-furrow tipping plow is preserved in working order in the German Agricultural Museum in Hohenheim.
