The next stage, after proper preparation of the field, is, of course, sowing seeds, for which we use today pneumatic seed drills and/ or mechanicalso that the entire operation on the farm can run smoothly and quickly. Without them, digging seeds into the ground and sowing them in rows in a multi-hectare field would not only be extremely difficult, but also time-consuming. Therefore, seed drills have become one of the most important agricultural machines on every farm. In this article, we will focus only on the first solution, namely pneumatic seeder, because it is distinguished by a more advanced structure that gives us many possibilities.

What are pneumatic seed drills?
Pneumatic seeder is an agricultural machine equipped with an innovative sowing system based on a vacuum or overpressure unit. The main element that distinguishes the machine from a mechanical seeder is the blower, which produces a high air stream to transport seeds in the coulters. Depending on the model, the blower mechanism may be driven by the PTO shaft or hydraulically. Thanks to this pneumatic seed drills they can work together with tractors that have less power.
What is a pneumatic seeder used for?
Machines intended for sowing seeds are composed of a special sowing unit consisting of coulters equipped with discs, holes, scrapers and press wheels. The sowing unit works together with the pump, which during operation generates a high air stream into the appropriate vacuum channels, so that the seeds from the tank go through the coulters straight to the bottom of the furrow created by the previous movement of the discs. After the grain is introduced, it is crushed by the pressure wheels. As a result, this allows the sown seeds to be evenly covered with a layer of soil, ensure good contact with the ground, and maintain the set operating depth of the coulters.
Why is it worth choosing a pneumatic seeder instead of a mechanical one?
Until recently, many people had negative opinions pneumatic seeder due to its complicated structure with an increased risk of failure. However, this is not entirely true, because innovative solutions appear on the market, and thus new models of seeders from various manufacturers who constantly improve their design. Moreover, the basic part of the machine - the seed distributing head - is solidly made of the highest quality material, ensuring long, failure-free operation. As with any other used agricultural machine, small working elements such as air ducts, V-belts or bearings may wear out, but replacing them is not too expensive.
Choice pneumatic seeder it brings many advantages, including the location of the seed box and its larger capacity, sowing precision similar to that of mechanical seeders, no need to constantly check the amount of seeds during work, and the ability to sow even small amounts of grain in the field. A perfect example is a machine Fortune Seeder created by Brastal company in cooperation with manufacturer AMJ AGRO. Why? Because it works based on its own hydraulics, electronic control using a touch display and, more importantly, it is equipped with as many as 24 seed pipes with sensors, ensuring precise operation at a width of 3 m. In addition, the model is presented pneumatic seeder allows farmers to achieve accurate sowing from 1 kg/h to 400 kg/ha at a speed of up to 20 km/h.
