Plows have existed for over 5000 years
The plow is a fundamental tool in farming, used to loosen or turn the soil before planting seeds or crops. The basic concept of the plow has existed for over 5000 years, with the earliest plows having no wheels and being pulled by animals such as oxen and horses. These ancient plows were based on the design of the hoe or shovel, and the use of animal power represented a significant advancement for prehistoric people.
Over time, the plow has undergone numerous transformations and improvements. For example, the Celtic people began using wheeled plows during the Roman era, and the heavy iron moldboard plow was invented in China during the Han Empire (1st and 2nd centuries). This Chinese plow was notable for its efficiency, requiring fewer animals to operate compared to European ploughs. The introduction of the curved moldboard and other design innovations in the 18th century further improved the plow's performance.
The 18th century also saw the increasing use of cast iron in plow construction, with the first cast iron plow patent issued to Charles Newbold in 1797. This century witnessed the emergence of replacement parts, allowing farmers to repair their equipment more easily and cost-effectively. By the 19th century, agricultural equipment began to transition from animal power to steam power, and eventually to combustion engines using kerosene or gasoline.
The invention of the steel plow by John Deere in 1837 marked another significant advancement in plow technology. The steel plow enabled farmers to more easily turn tough soil, enhancing agricultural productivity. In more recent times, companies like Bellota have continued to innovate by offering moldboard plows in different metals, such as boron steel, triplex steel, or case-hardened steel, to provide enhanced durability and resistance to wear and tear.
While the basic concept of the plow has remained unchanged for millennia, the ongoing evolution of farming equipment continues to bring improvements in efficiency, sustainability, and ease of use for farmers.

The first steel plow was invented in 1837
The steel plow was a significant advancement in agriculture, allowing farmers to easily turn tough soil. The steel plow worked by cutting through the soil, lifting it up, and turning it over. This process buried crop residue and helped control weeds, exposing fresh soil for planting new crops. The moldboard, or the part of the plow that turns over the soil, was also shaped differently. It was more of a parallelogram, with curved contours that made turning over the soil more efficient.
Deere drew inspiration from the way polished steel pitchfork tines moved through hay and soil and thought that the same effect could be obtained for a plow. In another version of the story, Deere used an old sawblade that had been polished from years of use. Using the steel from an old circular saw, Deere fashioned the first steel plow in 1837. The plow worked as expected, and Deere sold his first steel plow to a local farmer, Lewis Crandall, in early 1838. By 1841, Deere was manufacturing 75-100 plows per year, and by the mid-1840s, he and his business partner were manufacturing 1,000 plows per year.
The invention of the steel plow was a critical advancement during the period of agricultural reform in the 19th century. This century saw the use of cast iron as a material for farming equipment take off, as well as the introduction of replacement parts, saving farmers time and money. The 19th century also saw agricultural equipment turn away from horses and oxen as power sources and toward steam power, and later, combustion engines.

The moldboard plow was a major advancement in technology
The plow is a farm tool used to loosen or turn soil before planting seeds. It has been fundamental to farming for most of history. The earliest ploughs had no wheels and were drawn by oxen. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains.
The moldboard plow, also known as the turn plow, was a significant advancement in technology. It was invented in China's Han Empire in the 1st and 2nd century and subsequently spread to the Netherlands, which led the Agricultural Revolution. The moldboard plow was introduced to Europe in the early medieval period and underwent further design changes in the 18th century. These changes included the use of curved moldboards and the use of a single animal to pull the plow, rather than the four, six, or eight draught animals that were previously required. The 18th century also saw the invention of replacement parts, allowing farmers to repair their machinery more easily.
The moldboard plow works by using a broad blade (the share) to cut through the soil, a moldboard to turn the furrow slice, and a landside plate to absorb the side thrust of the turning action. The moldboard plow allowed for deeper furrows, which favored the sowing of seeds and helped to loosen the soil. The possibility of working on sloped ground and the use of plow bolts also improved the functionality of the plow.
The plow continued to evolve over time, with the development of the steel plow by John Deere in 1837, which allowed farmers to cultivate land more efficiently. In the 19th century, agricultural equipment shifted from using horses and oxen as power sources to steam power, and then to combustion engines. In 1963, the first 4WD tractor with an enclosed cab was introduced, and today, autonomous tractors are used in agriculture.

Tractors are now replacing plows
The evolution of farming equipment has seen a shift from ploughs to tractors, with the latter gradually replacing the former. While ploughs have been fundamental to farming for most of history, tractors have emerged as a more modern and mechanised alternative.
Ploughs, also known as plows, are farm tools used for loosening or turning soil before sowing seeds or planting crops. They can be made of wood, iron, or steel and have a blade attached to cut and loosen the soil. The use of ploughs can be traced back to ancient times, with the earliest ploughs dating back to around 1000 BC in the Ancient Near East. Over time, the design of the plough evolved, with the introduction of wheels and improvements in materials, such as cast iron.
Tractors, on the other hand, are more recent inventions that have revolutionised farming. The concept of tractors can be traced back to the late 19th century when steam power was replaced by combustion engines, which were more efficient and required less human interaction. The development of tractors continued in the 20th century, with companies like John Deere becoming major producers. Today, tractors have become even more advanced, with the introduction of autonomous tractors that can work without a human operator.
The advantages of tractors over ploughs include increased mechanisation, efficiency, and reduced human labour. Tractors can perform various tasks, such as ploughing, harrowing, and planting, without the need for multiple tools or animals for traction. They can also work in different weather conditions and have safety features to protect against obstacles. Additionally, tractors can be equipped with modern technologies, such as GPS guidance systems and stereo cameras, enhancing their capabilities and accuracy.
However, ploughs still hold value and relevance in certain contexts. In some regions, such as the Dust Bowl, ploughing may be approached with caution due to scarce and unpredictable precipitation. In such cases, no-till drilling and conservation tools like ploughs are preferred to maintain proper water drainage. Additionally, mouldboard ploughs are kept in equipment yards and used for specific purposes, such as breaking up terraces and corn stalk ground.
