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

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

A universal seed drill for variable establishment of several crops in one pass, including the option of supplementary fertilisation.
The double-chamber pressurised hopper enables seeding the crop together with inter-row fertiliser application in one pass, or mixing seeds with fertiliser in the dispensing piping. The fertiliser dosing and the selected seeding amount are completely independent of one another.
The OMEGA OO_FL universal seed drill can also be used for establishing several types of crop. One chamber can be filled with the main crop seeds, the other chamber with the intermediate crop seeds. The structural design makes it possible to seed the main crop together with the intermediate crop, 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 seeding unit while in production, for even higher machine utilization variability and crop establishment options. The seeding unit can be used for seeding a third type of seeds or applying micro-granulate when both hopper chambers are used for seeds. The seeding unit has a capacity of 400 litres.
The specially designed distribution head also allows seeding the crop in every other row, for example, for inter-row spacing of 25 or 33 centimetres. This solution is suitable for establishing oilseed rape crop. When using the OMEGA OO_FL seed drill for planting 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 leveller with the pneumatic packer. Perfect soil levelling before the drill coulters is an important part of seeding. The leveller breaks the rough furrow and levels off any unevenness, the pneumatic packer evenly compacts 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 seeding.
The OMEGA OO_FL universal 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 trace the tractor track.
The large and wide wheels mounted in an offset system under the hopper perfectly compact and level soil. The offset arrangement of the packer wheels increases soil and crop residue throughput, which reduces rolling resistance and thus the towing 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 drill coulters are attached to the seeding bar frame with a parallelogram. That allows the individual drill coulters to perfectly trace 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, in production, with drill coulters with an inter-row spacing of 12.5 cm suitable for most stubble breaking operations with a higher ratio of cereals in the seeding procedure, according to the customer’s requirements. The inter-row spacing of 16.7 cm is suitable for conditions with higher precipitation or with larger quantities of crop residue on the surface.
The OMEGA OO_FL seed drill with supplementary fertilisation 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 precision.
The double-disc seed drill with an offset disc cuts crop residue 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.

The hydraulic drawbar contributes to perfect terrain tracing.
The leveller is used for levelling coarse unevenness. The pneumatic packer stabilizes the seed drill during work and improves terrain tracing.
The disc section, arranged in the shape of X, with either serrated or aggressive discs with a diameter of 460 × 5 mm, ideally cuts and mixes crop residue with soil.
The fertiliser application coulters place fertilizer in the inter-rows. The fertiliser placement depth is adjustable independently of the seed placement depth.
The offset arrangement of packer wheels provides trouble-free clearance, even in wet conditions. The packer with wide wheels levels off and compacts soil before the drill coulters.
They spread ridges created between the individual wheels of the pneumatic packer.
Formed by double-disc drill coulters mounted on a parallelogram for perfect surface tracing. Optional inter-row spacing of 12.5 or 16.7 cm.
Comfortable calibration of the seeding mechanism and easy emptying of seeds from the hopper.
The ALFA-DRILL seeding unit 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 clayey soil thanks to the front leveller 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, supplementary inter-row fertilisation, and less travelling across the field thanks to quality prepared soil.”
