Position control
Move the draft control lever (2) fully down. Fix the implement position, inside or outside the soil, by moving the lever
(1) up for raising and down for lowering.
The implement movement is proportional to the movement range fixed by means of lever (1) .
Draft control
Move the position control lever (2) fully down, have the implement penetrated into the ground till reaching the desired
depth by gradually moving the lever (2) down.
The implement depth reached is proportional to the draft determined by soil hardness.
In this condition the rock shaft keeps the draft required automatically constant.
Once the draft is regulated at the end of the rope is possible to lift the implement with position lever (2) in order to
keep in memory the draft.
During last movement stroke of lever (2) a floating function is obtained and the rock shaft does not control the draft.
