Designed for establishing crops in partially or fully prepared soil, the CORSA CN mounted seed bar is used for establishing crops, such as cereals, oilseeds, grasses or catch crops. The seed bar is connected to the three-point tractor hitch (ideally combined with the FERTI-BOX FB_F / SEED BOX SB front hopper) or directly to the three-point hitch of the FERTI-CART FC or COMBO SYSTEM CS air-cart.

CORSA CN is a seed bar designed for establishing crops in at least partially prepared soil. The robust frame of the seed bar features double disc seed coulters with a parallel linkage. A great advantage of the CORSA CN seed bar is its high manoeuvrability, high area output and precise seed placement into the soil.
The double disc seed coulter cuts the plant residues and creates a clean and ready-to-use groove for even seed placement. The seed is then covered with fine soil and pressed downward with a depth wheel. The rear tine harrow is adjustable according to the existing soil and moisture conditions. The seed coulter features a parallel linkage, which ensures even seed placement at the set working depth along the entire working width of the seed bar.
The CORSA CN versatile seed bar can be equipped, as standard, 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 residue on the surface.
The seed drill can be equipped with seed 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.
CORSA CN can optionally be equipped with a pair of distribution heads that offer the option of switching off half of the working width of the seed bar to prevent unwanted placement of excessive seed.
Upon request, the versatile CORSA CN seed bar may be fitted with a tractor or pressurised air cart track eradicators. This equipment guarantees the loosening of the compacted tracks. Optional equipment for the CORSA CN model also includes support wheels track eradicators.
MATADOR MO is a seed drill designed for strip seeding and establishing crops. The CORSA CN seed bar is connected to a three-point hitch of the seed drill.
The single-chamber or double-chamber front hopper has a capacity of 1,900 or 2,200 l, respectively. The seed is conveyed pneumatically from the front hopper to the distribution head on the seed bar.
The COMBO SYSTEM CS trailed air-cart offers a total combined capacity of 5,000 litres. The seed bar is connected to the three-point hitch of the air-cart. The double-chamber design of the hopper allows two types of seed, or seed and fertiliser, to be sown in a single pass.
The FERTI-CART FC single-chamber pressurised air cart has a capacity of 3,500 l. The seed bar is connected to the three-point hitch of the air-cart. When connected to the CORSA CN 6000 seed bar, FERTI-CART FC offers the option to switch off half of the working width of the machine.

It can be fitted with double disc seed coulters with row spacing of 12.5 or 16.7 cm. The seed coulters are mounted via parallelogram for accurate seed placement into the soil.
CORSA CN can be accessorised at the front with TURBO/PROFI coulters, the Crushbar levelling bar or a tyre packer.
The support wheels are used to guide the machine smoothly through the terrain, stabilize the side frames and maintain the set machine working depth.
The track eradicators are used for loosening compacted tracks created by the tractor or air carts.
The track eradicators are used for loosening compacted tracks created by the support wheels.
They are used for the placement of fertiliser, seed or microgranulate onto the soil surface. The placement is conducted using application spreaders placed between the seed coulters.
It ensures the smooth flow of seed or seed with fertiliser to the individual seed coulters.
They are used to mark the following run of the machine. Suitable accessory for a seed bar carried by a tractor not equipped with GPS navigation.
The machine moves away from the ideal line and wobbles when seeding. That creates increased gaps, or so-called “eyes” between the individual rides in the field (with standard arrangement of the drill coulters). All those deficiencies are eliminated with our innovative design – the double edge drill coulters. When there is a deviation from the ideal line, the growth is only thinned locally without any significant gaps, or eyes“.
The double-disc drill coulters are attached to the seeding bar frame with a parallelogram. The design provides perfect terrain contouring and even seed placement at the same depth along the entire width of the machine.
“I like the seed bar. It helps us manage seeding by the agronomical deadlines and it also helped us expand the use of the COMBO-SYSTEM cart, which we use in connection with other BEDNAR machines.”

We know that everyone has different requirements for the optional machine equipment and its expected use. Therefore, you can specify your CORSA CN mounted seed bar to precisely match your needs.
The row spacing of 16.7 cm provides better material throughput. It is suitable for technologies with larger quantities of crop residue on the surface.
The row spacing of 12.5 cm offers plants better competitiveness against weeds and improves the engagement of the crop.
You are one step closer to your new machine.

CROP ESTABLISHMENT
Each crop requires specific conditions for its establishment, based on the selected soil cultivation technology and weather conditions. Generally, the crop should be established by the specified agronomic deadline to meet all the preconditions for achieving the required yield.
