Mounted grain mechanical seeder ASTRA 3 with double-disk single-row coulters and press rollers is designed for row sowing of seeds of grain, small-seeded, leguminous and other crops, similar in size and seeding rates to seeds of grain crops with the simultaneous and row soil rolling after traditional tillage. It was created taking into account modern design solutions that make it possible to significantly reduce the cost of agricultural products on the market.
With a working width of 3 m and a row spacing of 120 mm, the grain seeder can be effectively used in small areas under conditions of intensive agricultural technologies.
Weighing only 985 kg, the mounted seed drill makes the machine extremely manoeuvrable in the field and during transport.
The drill is supplied with a tramline metering wheel changeover set to match the tractor wheel width.
The sowing device made of polymeric materials is distinguished by maximum accuracy, continuity and smoothness of seeds supply of various forms and sizes for seeding rate from 1.5 to 400 kg / ha. The design of the reel allows for sowing small-seeded crops. An adjustment of the gap between the valve and the spool has been introduced, which makes it easier to sow large seeds with large rates.
Infinitely variable transmission mechanism (variator), which provides easy and quick adjustment of seeds and fertilizers seeding rates; provides more accurate and smooth adjustment in an increased seeding rate range (from 1.5 to 400 kg / ha) compared to a gearbox.
The front and rear shafts of the coulter hitch are connected by a screw rod. The screw is intended for group adjustment of the coulter travel depth.
Increased service life of the double-disc opener up to 100%, due to the use of boron-containing, increased hardness steels. The double-disc single-row opener allows sowing at the fields with a large amount of crop residues; the uniformity design of the coulter-press roller unit allows the coulter to be adjusted to a predetermined depth. ASTRA 3 has excellent planting depth control. The result is totally germination, which contributes to increased yields throughout the field. .
Electronic control system as a standard. ASTRA 3 is equipped with a new version of electronic seed control systems, which uses a new design seed flow control sensors with increased reliability and accuracy of determining of the seed flows density.
The production line was equipped with a powder coating line -Ideal-line (Denmark). This painting technology makes it possible to produce high-quality paintwork with a guaranteed service life up to 8 years.
