5.16.2 Coulter pressure, hydraulically actuated with seed rate increase
The coulter pressure can be adapted to the soil during operation when changing to heavy soil and vice
versa. The coulter pressure is adjusted hydraulically. Two pins in an adjuster segment act as the stop
for the hydraulic cylinder.
To achieve uniform levelling with the exact following harrow even on heavy soils, the exact following
harrow pressure is also increased when the coulter pressure is increased.
The coulter pressure is adjusted with a pin (Fig.
81/1). The second pin (Fig. 81/2) serves as a
stop for the hydraulic cylinder on heavy soil.
Fig. 81
The scale (Fig. 82/3) serves as orientation for
adjusting the pins.
Fig. 82
If pressure is applied on the tractor control unit (green 1), the coulter pressure increases and the
stop rests against the second pin. In floating position, the stop rests on the first pin.
The tractor control unit (green 1) serves to change the coulter pressure and the exact following har-
row pressure. When the tractor control unit is actuated, there is a simultaneous increase/decrease in
the coulter pressure and the exact following harrow pressure.
