HARVEST 420 PRO seeder is intended for drill seeding of grain-crops (wheat, rye, barley, and oats), leguminous plants (pea haricot beans, soya beans, pea everlasting, beans, lentil, chickpea, lupine) with introducing granulated mineral fertilizers. It may be used for planting of other crops similar to grain ones by the size of seeds and seeding rate (buckwheat, millet, sorghum, etc.).
The coulters pressure mechanism design has been reinforced to 80 kg to use the mini-till seeding technique and ensure a constant seeding depth.
The service life of coulters has been increased by 100% due to the use of modern technologies for processing boron steels. (BELLOTA Spaine)
Grain and fertilizer seeding units are made of polymeric materials to eliminate the possibility of corrosion and increase their service life.
The fl aps on grain and fertilizer seeding units have seven positions to regulate the seed fl ow to feed rollers.
Variators provide for a quick and easy adjustment of the seeding rate range:
- for seeds: 0.8 to 480 kg/ha;
- for fertilizers: 25 to 200 kg/ha.
The integral structure of the “coulter press roller” unit allows adjusting the coulter to a predetermined depth at 1 cm intervals.
