Mechanical grain seeders ALFA 4 - a new generation of grain seeders on the market from the ELVORTI company.
Mechanical grain seeders ALFA 4 - are designed for row sowing according to the minimum technology seeds of grain, legumes, rape seeds and flax with the simultaneous introduction of mineral fertilizers and rolling the soil in the sown rows.
Advanced and improved design for openers pressure mechanism on the soil. The new design with the hydraulic valve of compulsory pressure and a spring with increased rigidity could provides pressure for openers from 60 to 110 kg that allows to make seeding on the minimum technology, providing stable depth of sealing a seeds.
Constant hydraulic pressure, due to the installed shut-off valve, which allows you to fix the initially set coulter pressure. This function guarantees a consistently high quality of seed placement in the soil, allows you to maintain the uniformity depth of the coulters on uneven surfaces and under changing soil conditions.
Control valves (valve) allows the marker control to be operated with one handle from the tractor cab.
The largest bunker - – 1,500 l (grain - 1,200 l, fertilizer - 300 l), which allows sowing up to 28 hectares in daylight (with a seeding rate of 200 kg / ha of wheat and 100 kg / ha of mineral fertilizers), 5 hectares can be sown at the 1st load of the seeder.
A new hitch and transportations device, that allows you to transfer the seeder from transport to working position and vice versa, in 2 minutes. The transportations device in the basic configuration with wheels of increased diameter and strength provides additional protection against damage to tires by stems of plants and other objects on the surface of the field, with a transport width of 2.45 m, it allows you to move the seeder at public roads.
The ALFA 4 seeders are equipped with wide wheels with an increased contact with the soil and discs of reinforced profile, which allows you to reduce the pressure on the soil, and work with the seeder in the spring on a wetter and looser ground, as well as on the ALFA 6 seeders, a hub with an increased axle diameter and a bearing were used with higher lifting capacity, which increases durability and reliability when sowing in mini-till.
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.
The drive unit shafts of the fertilizer dispensers are made from stainless steel, which increases the durability of the shafts and the fertilizer dispensers, located on them and excludes their corrosion.
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.
Electronic control system "Monada" as a standard. ALFA 4 is equipped with a new version of electronic seed control systems (manufactured by OOO NPF MONADA), which uses a new design seed flow control sensors with increased reliability and accuracy of determining of the seed flows density.
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. ALFA 6 has excellent planting depth control. The result is totally germination, which contributes to increased yields throughout the field.
2 sets of choice "narrow, wide" Pressure Wheels are mounted on the seed drill, which ensures sowing in conditions of different soil moisture. To clean the press rollers and ensure a stable sowing depth, scrapers made of wear-resistant DUROSTAT 400 steel are installed, which increases the scraper operation life up to 2000 hectares. A version of the chain harvester has been developed, as an additional separate option on the ALFA 4 seeders, for leveling the soil and working on various backgrounds.
