3 Attachment and installation
3.1 Tractor requirements
Before installing the machine control unit, ensure that your tractor meets the following requirements:
• A minimum voltage of 11 V must always be guaranteed, even if multiple loads are connected
simultaneously (e.g., air conditioning system, lights)
• The PTO speed must be 540 rpm as a minimum requirement and must be complied with (basic
requirement for a correct working width).
On tractors without load-switchable transmission, the forward speed must be selected by
using the correct gear ratio in such a way that it corresponds to a PTO speed of 540 rpm.
• A 7-pin socket (DIN 9684-1/ISO 11786). Via this socket, the control unit receives the pulse for the
current forward speed.
The 7-pin socket for the tractor and the forward speed sensor can be obtained as an
expansion kit (option), see chapter 7 Special equipment
3.2 Connections, sockets
3.2.1 Power supply
The tractor supplies the machine control with power via the 3-pin connector (DIN 9680/ISO 12369).
