11.4.4 Pressure load on rollers - penetration characteristic
The pressure load on the rollers is determined by the position of the upper link
and the mounting position of the drawbar.
The hydraulic unit of the three-point linkage on the tractor must be switched to the
float position.
Drawbar
The drawbar should always be mounted in the upper mounting position.
The drawbar should only be mounted into the lower mounting position, when the
implement is unable to be raised far enough or when the upper link is in an opti-
mum position the pressure load on the rollers is too high.
The hydraulic unit of the three-point linkage on the tractor must be switched to the
float position.
Upper link
The mounting position of the upper link exerts an influence on the lift height, the
penetration characteristic and the roller pressure. The hydraulic unit of the three-
point linkage on the tractor must be switched to the float position.
