¾ respective machine. Introduction Cams AutoForce is a system for the automatic coulter pressure adjustment on the Maestro. A cam with a sensor is attached to the axle of the depth guide wheel. The sensor determines the force acting from the ground on the depth guide wheel.
Functional principle Forces on the drill unit Forces on the drill unit hydraulic coulter pressure force of the drill unit’s weight force between soil and depth guide wheel (target value) Force between soil and coulter discs The target value for the control of the coulter pressure is the force between the soil and the depth guide wheel (C).

The PWM value is to 0 while the water hole mode is active. In manual mode, the display in the start screen and the AutoForce detail screen is set to 0 kg and shown as blue output value. All softkeys for Manual changing the target value are shown in grey.
