Drill coulters with an inter-row distance of 16.7 cm
The inter-row distance of 16.7 cm provides better material throughput. It is suitable for technologies with larger quantities of crop residue on the surface.

The EFECTA CE wide seed drill has a working width of 12 metres. In its category, it is an extremely versatile seed drill, equipped with double-chamber pressurised hopper with a capacity of 6,000 litres. It can be equipped with four types of front equipment installed in front of the drill coulters. The large working width in combination with a high working speed guarantees achieving high daily outputs.

A highly versatile wide seed drill with the option of soil preparation in one pass, designed for maximum daily outputs.
EFECTA CE is an extremely versatile seed drill with a working width of 12 metres and exceptionally low demands for the tractor power. That provides high working speed and effectiveness of the whole set. The EFECTA CE wide seed drill can seed up to 20 ha/h. Even with this hourly output, EFECTA CE can establish crops with high seeding amounts.
The double-chamber version of the pressurised hopper enables seeding the crop together with inter-row fertiliser application in one pass, or mixing seeds with fertiliser in the metering piping. The fertiliser dosing and the selected seeding amount are completely independent of one another.
The EFECTA CE wide 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 subsidiary crop seeds. This 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 crops can be set individually.
To use the performance potential, both chambers can be used for one type of seed. It will reduce the time needed for refilling the hopper and increase the efficiency of the EFECTA CE wide seed drill.
The hydraulically controlled Crushbar levelling bar is especially suitable for the final surface levelling in front of the drill coulters. It is easily controlled using the hydraulic circuit from the comfort of the cabin.
PROFI coulters are specially shaped, hydraulically controlled discs. They enable the operator to quickly respond to the current conditions. It is important seed drill equipment for heavier soils.
TURBO coulters are sharp discs mounted behind the disc section. The coulters work in the same line as the rear drill coulters. It is important seed drill equipment when seeding directly into a stubble field, or in the catch crop.
FERTI coulter are used for fertiliser application. The fertiliser placement depth is adjustable independently of the seed placement depth. The coulters are designed with a spacing of 12,5/16,7 cm for a high throughput.
Automatic switching of the individual sections based on a GPS signal. EFECTA CE has four sections, each three meters wide.
Variable application of seeds and fertiliser (adjustment according to the seeding amount and dosage) based on the regulatory maps according to the machine position.
Two-way data transmission from PC to the screen terminal (seeded area, seeded amount and other data).
The required seeding amount can be entered in kg/ha or in units per m2 (in this case, seed HTS and germination capacity also have to be entered).
Allows setting the machine so that the seeds are in the drill coulters at the right time when starting, or lowering or lifting the machine into the working or headland position.
EFECTA CE is equipped with four distribution heads for even distribution of seed / fertiliser to the individual drill coulters and for the ability to apply high doses of fertiliser and seeds. That ensures the same distance to all drill coulters from the distribution head. This solution also offers a sectional control by every three metres of the working width.
The drill coulter sections are mounted on the side frames using a parallelogram and each drill coulter uses its own parallelogram within the proven PSP system. The combination of such mounting provides unparalleled terrain contouring and maintaining a constant depth of seeding along the entire working width.
The EFECTA CE wide seed drill can be equipped, as standard, with drill coulters with an inter-row spacing of 12.5 cm suitable for cropping systems with a high ratio of cereals in the crop rotation. The inter-row spacing of 16.7 cm is suitable for seeding with large quantities of crop residue on the surface.
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 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.
Even though the EFECTA CE seed drill has a working width of 12 metres, its transport on roads is easy and safe. The side frames of the seed drill fold forward and the transport length is only 7.8 metres. The wide arrangement of the transport wheels provides a good stability, even at higher speed. The compact dimensions also contribute to easy and fast turning at headland.
The fast and comfortable filling of the EFECTA CE seed drill hopper is ensured by an easily accessible and wide platform with railing 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.
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 seeding roller based on the type of seeds/fertiliser, working speed and seeding amount.

Used for loosening and levelling field unevenness after the wheels of towing vehicle.
They evenly level the unevenness behind the seed drill wheels and aerate the hardened surface.
The specially shaped PROFI coulters offer an excellent crumbling effect. They are suitable for heavier soils.
Provide even seed/fertiliser distribution to the individual drill coulters. They enable sectional control for every 3 metres of the width.
The individual sections of the seeding bar are suspended on a parallelogram on the side frames for perfect contouring. Optional inter-row spacing of 12.5 or 16.7 cm.
The drill coulters are mounted to the seeding bar sections using a parallelogram, which provides even seed placement at a constant depth level. Optional inter-row spacing of 12.5 or 16.7 cm.
The pressurised hopper enables seeding large amounts of seeds and improves the precision of seeding. The hopper is divided in the ratio of 60:40.
“The EFECTA CE seed drill impressed us above all with its robust construction compared to other seed drills. We expect long life and great durability.. Another reason why we chose this seed drill was the soil preparation section, we chose the version with PROFI coulters. We practice precision agriculture in this company, so one of the criteria for us was the section control function, which saves costs for seeds. From the summer establishment to the the autumn sowing of winter crops, we have planted approximately 4,000 hectares with the seed drill, the daily output depends on the conditions. We sowed 127 hectares in a 12-hour shift.”
