The SPRAYER-Controller MIDI 3.0 and MAXI 3.0 job computers are ISOBUS job computers that can control the operation of field sprayers.

The ISOBUS job computer is the control central of the sprayer. Several sensors are connected to the job computer, which monitor important implement parts. The job computer controls the implement based on these signals and on the operator's specifications. An ISOBUS terminal serves as an interface. All implement-specific data is stored in the job computer and is therefore maintained even when changing the terminal.
