FERTI coulters
FERTI coulters are used for applying fertiliser in the rows. The FERTI coulter creates a groove where the application end piece applies the fertiliser.

The OMEGA OO_FL versatile seed drill has double-chamber hopper divided in the ratio of 60:40, or 50:50. The hopper design enables seeding crop together with fertiliser placement, or seeding several crops at the same time, such as the main and companion crop, all in one pass. The OMEGA OO_FL seed drill has an outstanding light design, a disc section, and a wide range of optional equipment, including two row spacing options of 12.5 or 16.7 cm.

„This seed drill, equipped with large tyre packers, consolidates the soil well, and the offset wheel system is really well thought-out. It’s a seed drill that’s very well thought out for everything. That’s why we chose it and we don’t regret it at all..“
Join us in our series to meet BEDNAR OMEGA seed drill users who have bet on the quality of these versatile seed drills.
Find out moreThe double-chamber pressurised hopper enables seeding the crop together with row fertiliser placement in one pass, or mixing seeds with fertiliser in the dosing unit. The fertiliser dosing and the selected seeding amount are completely independent of one another.
The OMEGA OO_FL seed drill can also be used for establishing several types of crops. One chamber can be filled with the main crop seeds, the other chamber with the subsidiary crop seeds. The structural design makes it possible to seed two crops together, bringing new agronomic opportunities in response to the current farming requirements. The seeding amount of the individual crops as well as their placement in soil can be set individually.
To use the performance potential of the machine, both chambers can be used for one type of seeds. It will reduce the time needed for refilling the hopper and increase the efficiency of the OMEGA OO_FL seed drill.
The OMEGA OO_FL seed drill can be equipped with the BEDNAR ALFA DRILL seeder for even higher machine versatility and crop establishment options. The seeder can be used for seeding a third type of crop or applying micro-granulate when both hopper chambers are used for seeds. The seeder capacity 400 litres.
The specially designed distribution head also allows seeding the crop in every other row, for example, for row spacing of 25 or 33 centimetres. This solution is suitable for establishing oilseed rape. When using the OMEGA OO_FL seed drill for establishing two crops in every other row, you can place each crop at a different depth level. The drill coulter support wheel can be set at various holes with a spacing of 20 mm. Adjusting every other support wheel sets a different seeding depth in the even coulters than in the odd coulters.
No other seed drill on the market offers the option to combine the front levelling bar with the tyre packer. Perfect soil levelling before the drill coulters is an important part of seeding. The Crushbar breaks the rough furrow and levels off any unevenness, the tyre packer evenly consolidates soil along the entire width of the machine, and contributes to maintaining its stability at high working speed.
The working section behind the disc section is definitely what makes BEDNAR machines distinct. It can be equipped with the popular PROFI coulters for better soil cultivation, or TURBO coulters for creating a groove for drill coulters in the case of direct drill.
The OMEGA OO_FL seed drills have disc sections arranged in the shape of X. This innovative technical design eliminates drifting of the machine to the side. That allows the machine to precisely follow the tractor track.
The large and wide wheels mounted in an offset system under the hopper perfectly consolidates and level soil. The offset arrangement of the tyre packer increases soil and crop residues throughput, which reduces rolling resistance and thus the power demand. The wheels can be easily replaced in the case of a puncture! The wheels are mounted independently and the seed drill turns at headland using the packer, except for the two central wheels, which prevents the undesirable formation of tracks.
The double-disc seeding coulters are mounted on the seed bar frame with a parallelogram. That allows the individual drill coulters to perfectly contour the terrain and place seeds evenly at a constant depth level along the entire working width.
The OMEGA OO_FL variable seed drill can be equipped with drill coulters with an row spacing of 12.5 cm suitable for cropping systems with a high ratio of cereals in the crop rotation. The row spacing of 16.7 cm is suitable for seeding with large quantities of crop residues on the surface.
The OMEGA OO_FL seed drill with supplementary fertiliser placement is equipped with two distribution heads, which makes it possible to deactivate a half of the working width of the machine – mechanically, or electronically from the comfort of the tractor cabin. It prevents undesirable excessive seeding.
The seed drill can be equipped with flow sensors on request. The device ensures that if a drill coulter gets clogged, the information is displayed on the screen. That guarantees maximum seeding accuracy.
The double-disc seeding coulter with an offset disc cuts crop residues and creates a clean and prepared groove for even seed placement. There is either a standard, or carbide scraper between two discs. The seeds are then covered with fine soil and pressed down into the soil by the depth wheel. The depth wheel is available in two sizes: 330×50 mm and 330×65 mm.
The fast and comfortable filling of the OMEGA seed drill hopper is ensured by an easily accessible platform and steps. To fill the hopper, the steel lid swings by 90°. The hopper filling level is indicated by two sensors. One is installed higher and its angle is adjustable, the other one is installed in the lower third of the hopper.
We have developed the OMEGA seed drill also with an easy and comfortable operation in mind. The seed calibration at the rear of the machine is also easy – a calibration bag is simply placed below the pipe. You do not need to climb the disc section and perform complicated calibration under the hopper. The outlet also makes it easy to empty the hopper contents.
Emphasis was placed on easy control when developing the OMEGA seed drill. The seed drill can be connected to the tractor via the ISOBUS technology, or it can be controlled using a BEDNAR ISOBUS display. A series of control displays with basic or advanced control functions are available.
BEDNAR developers designed an application for mobile phones that provides easy and simple calibration of the seed drill from your mobile phone. The mobile application includes a guide that helps with the right selection of the seed matering roller based on the type of seeds/fertiliser, working speed and seeding amount.

Take a look at your future machine.
The hydraulic drawbar contributes to perfect terrain contouring.
The levelling bar is used for levelling coarse unevenness. The tyre packer stabilises the seed drill during work and improves terrain contouring.
The disc section, arranged in the shape of X, with either notched or aggressive discs with a diameter of 460 × 5 mm, ideally cuts and mixes crop residues with soil.
The fertiliser coulters place fertiliser in the rows. The fertiliser placement depth is adjustable independently of the seed placement depth.
The offset arrangement of tyre packer provides trouble-free clearance, even in wet conditions. The packer with wide wheels levels off and consolidates soil before the drill coulters.
They spread ridges created between the individual wheels of the tyre packer.
Formed by double-disc seeding coulters mounted on a parallelogram for perfect surface contouring. Optional row spacing of 12.5 or 16.7 cm.
Comfortable calibration of the seed metering unit and easy emptying of seeds from the hopper.
The ALFA-DRILL seeder allows seeding a third type of seeds or applying micro-granulate when both hopper chambers are used for seeds.
The pressurised hopper enables seeding large amounts and improves the precision of seeding.

“OMEGA OO_FL perfectly processes even heavy clayed soil thanks to the front levelling bar and the disc section, it prepares a quality seedbed, and distributes seeds evenly. As far as the quality of seeding is concerned, I am satisfied. We purchased the seed drill according to the technical parameters we required – seeding two crops, row fertiliser placement, and less travelling across the field thanks to quality prepared soil.”
