The booms can be equipped with an automatic boom height control. Ultrasoon sensors measure the distance from the spray boom relative to the soil / crop. An inclination sensor measures the position of the chassis and where necessary the Distance Control regulates the required flat position and altitude. From the tractor cab, the amount can be set. An option for the sprayer can be: that when the sprayer is switched off that the system automatically lift the booms and when it is switched on again the booms will automatically return to the position from the previous height setting.
