Grain seeder John Deere 750 harrow 3.1 m, 90th coulter, all sowing technologies and No-Till

Mechanical grain seeder John Deere 750 from the USA
The working width is 3.1 m, 4.6 m and 6.1 m. A small working width allows you to use a tractor with a small power. With the seeder 750, it is possible to sow grain crops with mineral fertilizers, as well as small-seeded crops and grasses with a row spacing of 19 cm. The seeder is equipped with a single-disc coulter for working on the zero-technology soil treatment "Series 90" for simultaneous sowing and application of granular mineral fertilizers.(//tractor-service.com)
The John Deere company patented single-disc coulters of the 90 series, their presence provides 2 main advantages:
• effective work even with a large amount of plant residues;
• insignificant destruction of the soil layer.
Thanks to the high pressure of the coulter on the soil (up to 181 kg), uniformity of sowing depth is achieved on an uneven, unprepared field. The sowing depth can be adjusted individually on each coulter. Coulters are placed in 2 rows, thanks to which it is possible to work with a double row spacing (option). Seeders from the John Deere company are characterized by reliability, sowing quality, as well as ease of operation and maintenance.
