Koppert Machines manufactures various sowing machines, from drawing to self driven sowing machines. The most important part of our sowing machines is the sowing element. Because of this part the machine is suitable for sowing of most seeds untill a diameter of 4 mm.
The "single" sowing
Throughout the years Koppert Machines developed a sowing unit, which has proved in practice to meet the highest requirements. These units are on all our sowing machines. Therefore the machine is capable of sowing almost all kinds of calibrated, coated and non-coated seeds up to a diameter of 4 mm. Some examples are: radish, spinach, corn-salad, rettich, tomatoes, salad, carrot, leek, celery, caulbi-flower, cabbage, winter-carrot and a large variety of flower seeds from celosia till sun-flowers.
The "double" sowing unit
This unit is especially developed for the season with high production per m2. With the coulter, which is specially constructed for the sowing unit, the seeds will be put into the ground in a line with certain distances.
In the single as well as in the double unit, you will find an interchangeable sowing disc. The standard sowing discs are provided with 60 or 80 holes. Depending on the type of seed and the diameter different types of sowing discs can be mounted. One side of the disc is by the filler unit. The other side is the vacuum space and cleaning position. During the sowing, the seeds will be sucked on against the sowing disc. The adjustable scraper takes care that per hole only one seed will be sucked in. When the lowest level (no vacuum) is reached, the seed falls of the disc into the ground. The disc hole stays clean by means of the scraper and press air. Because 40% of the sowing unit is open, it is very easy to inspect the operation of it. The cover and the sowing disc are manufactured of stainless steel, the protection cap is manufactured of artificial materials and the sowing mechanism is manufactured of aluminum. These are all high quality products, to guarantee trouble-free sowing
All together this means:
"perfect functioning, little maintenance and very long life-time!"
