ASTRA NOVA 5.4A is a new generation of seed drills for regular sowing of grain seeds (wheat, rye, barley, oats),
legumes (peas, beans, soybeans, lentils, beans, flax, chickpeas, lupins), small-seeded crops (rapeseed, mustard), loose and medium-loose grass seeds, with the simultaneous application of mineral fertilizers and rolling of the soil in the sown rows. ASTRA NOVA 5.4A of the new generation has a number of advantages: a hopper for seeds and fertilizer with a volume increased by 1.5 times (fat - 500 dm3,
grains - 1000 dm3); a system of stepless regulation of sowing rates of both seeds and fertilizers; grain and fat seeding devices made of polymer material; combined coils of grain seeding devices; two-disc coulters with offset
discs made of boron-containing steel.
Grain and fat seeding devices are made of polymer material, which eliminates the possibility of corrosion of device parts and, accordingly, increases the service life. The sowing apparatus for the seeds of grain and leguminous crops is equipped with a valve that has three fixed positions that regulate the rate of seed supply to the screw coil. The grain seeding device has a screw coil for sowing grain and leguminous crops and a pin coil for small-seeded crops (rapeseed, mustard), as well as sowing loose and medium-loose grass seeds.

The seeder for small-seeded crops is also equipped with a separate flap that has three fixed positions that regulate the rate of seed supply to the pin coil. Instead of gear mechanical transmissions, variators are installed on the seeder, separately on the shafts of grain and on the shafts of fat seeding devices, which ensures fast and accurate regulation of the sowing rates of both seeds and fertilizer. Handles for group opening (closing) of valves in seeding devices are installed on the shafts of grain and fat seeding devices.
