A good knowledge of agricultural machinery and equipment, in addition to the skills required for planting plants and growing crops, plays an important role in the field of crops regarding the speed and quality. It is one and a large part of the economy. The history of agricultural machinery cultivation is old and can be traced back to the Chinese. Prior to the development and use of these machines, seeds were hand-poured into the soil after digging to prepare the soil for planting, carrying them to the heart after the part. planting was done. the land. Naturally, this was very cumbersome and difficult to do on a farm of several acres. Today, however, the increased efficiency of agricultural machinery has made farming more demanding and destructive than ever before. Today, in the agricultural industry and product production, speed and especially quality are the first words. The popularity of agronomy and organic products meant something important besides speed and quality, which was the natural nature of the product and the absence of chemicals to achieve a high quality, healthy product. 
agriculture understands this well and aims to produce products that put health first. Agricultural machinery and equipment are classified into three categories:
- Planting machine
- Machine repair
- Harvester
Planting machines are classified into three types: seeding machines, planting machines, and potato planting machines.
- Sowing machines
Centrifugal seeding (dispersed seeding): As the name of this agricultural machine suggests, the process of sowing seeds through this agricultural machine is dispersed and disorganized. Although the mechanism of this sowing machine is complicated, its advantage over manual seeding is that it can sow seeds evenly and regularly in the ground. Also, this form of agricultural machinery increases speed and costs. 
Linear Sowing: The mechanics of these agricultural machines is to first open a sickle on the field to put the seed into the sickle, and these machines themselves cover the seed. This eliminates the need to manage seeds in the soil. Some of these machines are equipped with this device that can be used to set the proper planting depth, distance between rows and the ability to prepare seed in the upper unit. All these factors increase work speed and prevent staff reductions.
- Planting machines and planting trays - Cider Greenhouse
On the other hand, there are also seeders for greenhouses. Greenhouse seeders are very different from field seeders. This means that the machine sows the seeds in special trays. These machines are also known as seders or greenhouses. The tray seed planter can be used to grow a variety of flower, plant and vegetable seeds in trays. A container seeder is usually connected to the seed line along with a container filler, dibbler (hole irrigation hole), soil sprinkler, and irrigation unit, ready to replant the container into the greenhouse in one operation. 
When choosing a tray seeder, it is important that the seed bar or drum is suitable for the type of container and seed used. If you want to use different types of seeds and trays, most tray seeders have seed bars and drums Please note that they are interchangeable. Most tray growers use a pneumatic system that vacuums the seed and sows it into the tray. Plateau cedars can generally be adjusted very precisely to accommodate one to two plants. Suction power and vacuum exhaust power can also be finely adjusted. The technology used ensures accurate and reliable results. Two of his commonly used pneumatic tray seeders are described below.
- Tray seeders with nozzles or needles
Pneumatic nozzle seeds, such as the Visser Granette, take one seed per (vacuum) nozzle and release it into a pot or dish cell. Seed bars match columns and trays. Seeds are sucked up by a nozzle from an open vibrating seed container. Different types of seeds can be planted in bowls by placing different needles or nozzles on the cedar bar. 
This type of tray seeder is relatively easy to adapt, so if you are planting small amounts of different seeds , nozzle seeders are best suited.
- Drum tray seeding machines
A pneumatic seed maker sucks the seed through a small hole on the planting side. The cocoon rotates on the opposite side of the planting carrier and releases seeds into the cell or dashpot. Many bell seeders also have a clicker to smooth out small holes. Line up the drum according to the pot size and seed size. Drum seed is suitable for a large number of seed (large volume). In addition, they can grow heavier seed varieties. If you want to know more about these machines, please click the following links.
- Advantages of agricultural machinery for cultivation:
- Increase planting speed
- Limit the number of seeds you consume
- Precise and adjustable planting depth
- Sow unity and order
- Maintenance and repair of farm equipment
A major cause of damage to agricultural machinery is water, which causes corrosion. Chemical fertilizers absorb moisture and quickly dry up. To prevent this, we recommend cleaning the feeder at the end of the job. The key to keeping your equipment running and performing at peak performance is no secret. Anyone who has been successful in farming knows that maintaining farm tools and equipment is everything. They know the reasons for maintaining agricultural machinery and its value in operating it. Proper maintenance of agricultural machinery reduces the costs required to keep your farm running at peak efficiency, extends the life of your tools and equipment, and prevents accidental breakdowns. Proper maintenance of agricultural machinery reduces the costs required to keep your farm running at peak efficiency, extends the life of your tools and equipment, and prevents accidental breakdowns. It may seem irrational to an outsider to spend so much time and money maintaining agricultural machinery, but it is meant to be engaged in agribusiness and to remain on profitable farms. Farmers know that upkeep is far cheaper than paying for even more expensive repairs.
