TwinTeC+ 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 additionally pushed against the ground. This causes an overpressure in the coulter pressure cylinder which is directly returned to the oil circuit. The coulter pressure is maintained.
Hill: When passing a hilltop the coulters are lowered resulting in an underpressure in the coulter pressure cylinder which is immediately compensated with additional oil from the circuit. The coulter pressure remains constant.
