Double-disc coulter colter for Great Plains seeder

Coulter double-disk "Green Plains" with two springs
It is intended for use in seeders for direct sowing, as well as for work using mini-till and no-till technology.
Standard on Green Plains Series planters, the dual-disc openers consist of a pair of robust 4mm wide discs that are offset from each other to effectively form the seedbed. The discs are protected by the design of the coulter frame - a casing is installed in front.
Thanks to its so-called. "Pendulum" fastening design and installed two coulter pressure springs ensures the repetition of the field surface relief and the stability of the sowing depth in various types of soil.

The T-handle allows you to adjust the working depth by setting it to one of 19 positions.
