Maize seed drill which is the best?

Maize, due to its requirements, needs an even distribution of seeds in the rows, which is crucial to ensure identical emergence conditions for each plant. This is why maize sowing is carried out with precision seeders.

Maize seed drills, why is spot sowing important?

Spot sowing is a key process in agriculture, which involves placing individual seeds in the soil with appropriate spacing between them. This method of sowing is vital for optimal plant growth. With the precise placement of seeds by maize drills in the soil, precision seeding ensures that each seed has adequate space to develop. Proper seed spacing eliminates competition for resources such as sunlight, water and minerals. Spot sowing maize seed drills are specially designed to place seeds with high precision, both in terms of distance and depth below the soil surface. This enables efficient use of the seed and minimises wasted areas in the field. In crops such as maize, where spacing affects the quality of the crop, precision seeding enables precise spacing control. As a result, spot sowing contributes to uniform growth and healthy crop condition, which is key to achieving maximum yield.

The principle of maize seed drills.

Maize seeders can be divided into two main types: mechanical and pneumatic. They differ in the way the seed is placed in the soil. In this article, we will focus on pneumatic seeders.

Pneumatic seed drills are faster and more precise compared to their mechanical counterparts. One of the main advantages of this type of seeder is also its ability to work on wet soil. The principle of operation depends on the type of system used. There is mainly a vacuum system (often used in HMS maize seed drills) and a positive pressure system.

In a vacuum seeder, the seed is pressed against the disc opening by the vacuum and then transported from the hopper to the coulter. On the other hand, in a positive-pressure drill, the air flow presses the seed into the disc opening while removing the excess into the hopper.

These systems also differ in their operating speed. The vacuum seed drill allows seeding at speeds of up to 11 km/h, while the positive pressure seeder is capable of precise seeding at speeds of up to 20 km/h, making it a common choice for large-scale farms.

The most popular maize seed drills and their equipment.

Maize seed drills vary in the number of rows or seeding sections, depending on the working width and row spacing. LUPUS offers popular 4-row models such as the HMS Pinadisc, as well as 6-row models with a 75 cm row spacing frame. Also available are 6-row seeders with a telescopic frame that can be hydraulically extended, allowing row widths from 45 to 75 cm to be adjusted.

HMS equips maize seeders with modern electronic control and seeding control systems, which include sensors and an on-board computer. The control systems make it possible to adjust seeding parameters such as seed quantity and distance, speed of the agricultural tractor. In addition, they allow the detection and signalling of errors and failures, such as gaps, double seeding, coulter blockage, missing seed or low air pressure.

On all models, the seeder sections are driven by a gimbal shaft, ensuring a stable drive and easy section disengagement. A simple gearbox allows the desired seed rate to be set.

The clod scraper is the first component of the sowing section, which has the form of wings as standard. Its task is to clear the strip of soil on which seeding takes place.

The HMS maize seeders have a disc seeding section, which enables quick and precise spot seeding of maize, beet, sunflower and other crops on a variety of soil types – whether well-tilled, poorly prepared or in mulch..

The seed placement is located at the point of contact between the seed wheel and the soil, which guarantees precise seed depth maintenance even in undulating terrain and on poorly seasoned soil. The seed pressure wheels, which are independent of the sowing depth, allow the soil around the seed to be properly compacted without the formation of a crust.
