About second-hand Pneumatic sowing machines

Pneumatic precision seed drills are used for sowing all types of fine seeds at precise distances and depths. Depending on the type of seed discs and the pneumatic precision seed drill, onions, carrots, endives, beans, corn, leeks, spinach, lettuce, radishes, sunflowers, and various other vegetables can be sown.

Here you will find an overview of the used pneumatic precision seed drills currently available for sale at Duijndam Machines. We sell many used precision seed drills from brands such as Monosem, Agricola, Gaspardo, Kverneland Accord, and Koppert. Our staff is ready to assist and advise you in finding the most suitable seed drill for your type of vegetable or flower.


Difference between a mechanical seed drill and a pneumatic precision seed drill

There are different types of seed drills on the market, such as tray seed drills for sowing trays, but there are also various types of seed drills for field use. The most commonly used type is the (pneumatic) precision seed drill. As the name suggests, the difference between a mechanical and pneumatic seed drill lies in how accurately the seed is sown within the row. While both types sow the seed at a pre-set depth and row distance, they differ in how the seed is placed in these holes. A mechanical seed drill rotates a seed disc, cam, or brush through the seed hopper, allowing one or a few seeds to enter the seed furrow. This technique is not always precise or consistent.

On the other hand, a pneumatic seed drill, as the name suggests, operates on air pressure. In this type of seed drill, the seed disc also rotates through the seed hopper, but the seed is sucked into the hole by a vacuum. This ensures the desired precision for vegetables such as onions, carrots, parsnips, corn, and beets.


Operation of a pneumatic precision seed drill for vegetables

The sowing element contains a rotating seed disc that uses air pressure to hold the seeds in place. This disc has regularly spaced holes through which the seed is vacuumed when it passes through the seed hopper. Scrapers that run along the disc ensure that only one seed is retained in each hole. Then, the vacuum is released above the seed furrow, and the hole in the seed disc is also cleaned by compressed air. This allows the seed to be placed in the ground, covered with soil, and compacted.

The sowing distance is determined by the number of holes in the seed disc, and it can also be adjusted using gears. The size of the hole (in millimeters) determines the type of seed that can be sown with the pneumatic precision seed drill. These seed discs can be exchanged, allowing the same precision seed drill to be used for sowing multiple types of vegetables and/or flowers. If the desired seed discs are not included with the pneumatic seed drill, they can be ordered separately.


Onion Seeding Machine

When dealing with expensive microseeds such as alfalfa, rapeseed, and onions, using a precision seed drill is advisable. Consistent sowing at a fixed distance within the row is important for onion seeds. With the pre-set seed disc, only one seed is vacuumed into the furrow at a time and then sown at a consistent distance and depth. This makes the pneumatic precision seed drill perfect for sowing onions. The holes in the seed discs of an onion seeding machine are typically around 1.0 mm, although there may be slight variations depending on the seed.


Carrot Seeding Machine

Many elements of an onion seeder can also be used as a carrot seeding machine. Sometimes, seed furrows for two rows or wider seed furrows are used for carrots to increase the number of seeds sown per hectare.


Corn Seeding Machine

The seeds for corn, beans, and sunflowers are larger, so a corn seeding machine is equipped with larger elements. The seed discs have holes larger than 2 mm, and the furrow openers, seed hoppers, and seed containers are larger compared to an onion seeding machine.
