Get mobile access to the AEF ISOBUS Database. Who is responsible when something is incompatible – the tractor manufacturer or the device manufacturer? How can I find an implement for my ISOBUS tractor which is also fully ISOBUS-compatible, and with which I can benefit from significant advantages? Is the implement that I already own ISOBUS-certified and compatible with the new ISOBUS tractor that I want to buy? And if so, which functionalities can I use with both of them? The AEF database answers these and many other questions. This database contains all relevant information about all machines and devices, which have been ISOBUS-certified so far. With just a few mouse clicks the user can configure his tractor/implement combination and immediately see whether the selected combination is compatible, and with which common functionalities it is equipped. The user can even compare alternatives. Selected ISOBUS combination can be sent easily by using the „Tell-a-friend“ function to the desired person. If a device cannot be found in the database, it is not certified. Existing user accounts can also be used for the mobile version of the database.
