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.

After the sowing part of the coulter, there is a knurled wheel according to the Chicken-Tracker principle.
The T-handle allows you to adjust the working depth by setting it to one of 19 positions.
