NOTE
These operating instructions are only valid in
combination with the E-Manager Midi 10.07 or
higher operating manual.
This document only describes the function of the
AutoForce automatic coulter pressure control.
¾Always follow the operating instructions for
drill and E-Manager to ensure safe operation
of the machine.
AutoForce
Introduction
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.
The objective is keeping the contact force be-
tween depth guide wheel and ground constant,
regardless of the soil conditions.
As a result, the coulter unit adapts to di󰘯erent
soil conditions to ensure consistent placement
depth.
The systems may have a single or multi-section
design. For systems with one section springs are
attached to the drill unit in the track.
For systems with several sections, the respec-
tive last section is reserved for the track. Springs
can be retro󰘰tted.
NOTE
The user is responsible for the quality of sowing
in spite of the AutoForce automatic coulter pres-
sure control.
¾Check the quality of sowing and placement
depth in the 󰘰eld several times a day.
¾Check the calibration values of the sensors
several times a day. Observe the section
Calibration (teach) of sensors.
Checks before starting
work
Coulter unit
¾Observe the basic setting of the coulter unit
to ensure the function of AutoForce.
¾Adjust the parallelograms of the units hori-
zontally.
¾With the Maestro 16/24/36 SW check the
setting of the coulter rail in addition.
¾Observe the operating instructions of the
respective machine.
Cams
A
Sensors with cams (A)
¾Check cams for wear.
Unequal wear of cams causes di󰘯erent place-
ment depths.
¾Replace the cams if necessary.

Functional principle
Forces on the drill unit

D
Forces on the drill unit
A hydraulic coulter pressure
B force of the drill unit’s weight
C force between soil and depth guide wheel (target value)
D 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).
On soft soils, the force of the weight is su󰘲cient for the coulter discs to penetrate the soil.
On hard soils, the force between soil and the coulter discs (D) increases. As a result, the force (C)
between the soil and depth guide wheel becomes smaller. The target value is therefore undercut.
The coulter pressure (A) must now be increased hydraulically for the force (C) between soil and
depth guide wheels to correspond to the target value again and the placement depth to remain
constant.

For greater clarity, the presentation of the weight force and the force between soil and depth guide
wheel is omitted on the following illustrations.

Sowing on soft, moist or light soil
Placement depth H is maintained. The force
acting from the soil on the coulter discs is
relatively low.
Sowing on hard soil, clod-type soil or rocky soil
The force acting on the coulter discs increases.
The placement depth decreases.

Sowing on soft, moist or light soil
Placement depth H is maintained. The force
acting from the soil on the coulter discs is
relatively low.
Sowing on hard soil, clod-type soil or rocky soil
Additional coulter pressure is hydraulically
applied to the drill unit to allow deeper pene-
tration of the soil.
Placement depth H remains consistent.
