Plow is called the tool used in agriculture to generate furrows in the land and tillage. The plow can move by mechanical action or through the force of an animal.
With the plow, ditches or ditches are created in the ground and the soil is removed. Once the plow has fulfilled its function, planting proceeds. The action performed with a plow is known as plowing.
According to DigoPaul, the plow is one of the most important inventions in the history of agriculture, and dates back to several millennia before Christ; specifically, the oldest evidences of this tool take us to the second half of the 4th century BC, in the Middle East; Thanks to their incorporation into agricultural activities, the work of the workers became much easier, since until then they used shovels, picks and hoes to carry out the sowing of the seeds.
The first plows were pulled by human beings, who had to exert great force to move the mechanism across the field. Despite the physical effort that people from the lower classes had to do, planting became much more profitable than before, and this translated into a benefit for everyone, to a greater or lesser extent.
The oldest plows were made entirely of wood. When the Romans implemented the use of an iron blade, they also began using animals such as oxen, horses, and mules to mobilize the plow. Thereafter, manufacturers sought to adapt the design to the presence of draft animals. Although nowadays it is usual for a tractor to be used to pull the plow, the use of horses is still continuing, something absolutely unnecessary given the technology we have.
It is very important to highlight that animal exploitation is a problem to be solved, something that the human being should leave behind once and for all. Tractors are no longer a novelty or a luxury item, so their cost should not be an excuse to avoid them. Although horses, mules and oxen are much stronger than us, this does not mean that they must or want to undergo this type of work, nor that their bodies do not suffer after long hours of forced activities.
As with the replacement of traditional plowing by motorized plowing, there are other movements that focus on protecting animals from exploitation by offering entrepreneurs mechanical alternatives. For example, there are several initiatives that seek to eliminate the use of horses to pull the typical tourist carts of large cities; instead, they propose using motorized vehicles, even horse-like (although the latter is not exactly a very animalistic touch).
These modern plows, made of metal, are integrated into a chassis that hooks to the tractor. In the lower sector appears a piece known as a swallow, which can be replaced since, with the intensive use of the tool, it suffers significant wear.
According to the task they perform, you can differentiate between different kinds of plows. He who only works on the surface of the land is called a cultivating plow, since he prepares the land for planting. Other plows can turn the soil (disc plow), dig it and displace it (plow with moldboard) or even create conduits that favor the drainage of water (rotary plow).
Arado, finally, is the name by which the Arado Flugzeugwerke company was known. This German company, dedicated to the manufacture of aircraft, was founded in 1925 and was in operation until 1945.
