3.5.2.1 Hydraulic Adjustment

Fig. 8. Hydraulic adjustment of the drag working depth
Hydraulic adjustment involves pressurizing the cylinders [A] from the tractor cab causing them to
be extended / retracted depending on the required working depth of the drag. Do not set the
hydraulic system in the floating position.
In order to align the position of the individual sections of the drag, unload all its working
components (by lifting the drag above the ground by means of the tractor suspension or the
machine chassis) and apply pressure to the cylinders several times to maximize their retraction
and extension. Always set the working depth by extending the cylinder.
Each time after finishing work and before transporting the machine, set the drag in its extreme
position in relation to the roller (i.e. extend the cylinders.)
