TwinTeC plus coulter pressure
Setting the coulter pressure via the ISOBUS terminal is standard. The coulter reliably maintains the pressure selected. This is of special benefit when sowing shallow in very hilly terrain.
Hollow: when passing through a hollow, the coulters are pressed against the ground. This creates an overpressure in the coulter pressure cylinder which is transferred directly to the oil circuit. The coulter pressure remains constant.
Hilltop: the coulters are lowered when going over a hilltop. This results in an under-pressure in the coulter pressure cylinder which is immediately compensated for with additional oil from the circuit. The coulter pressure remains constant.
