Parallel driving device
A parallel driving device is an aid to driving straight ahead in the field . With the help of a parallel driving device, overlaps or gaps between the individual cultivation strips in the field can be avoided. In addition, parallel driving devices facilitate subsequent driving and sometimes offer fully automatic headland management . In poor visibility or at night, work in the field is only possible in this way. This means that larger areas can be ordered with less effort, which also reduces operating costs.
The disadvantage here are the often relatively high costs of a single device (up to € 40,000), and only newer agricultural machines are prepared for the installation of parallel drive systems.

Power steering
Steering aids only show the driver the lane to be driven via a display. The accuracy depends on the implementation of the instructions and the accuracy of the equipment used. In the simplest case, PDAs or other devices with a GPS receiver can also be used.
Steering assistant
Steering assistants intervene in the steering directly via a motor with a friction wheel on the steering wheel or the steering column . The relief for the driver is much greater here than when driving with a steering aid. This type of parallel driving device can be used relatively easily with several vehicles.
Automatic steering
Automatic steering systems also intervene directly in the steering; in contrast to steering assistants, they change the direction of travel directly in the hydraulic system and therefore require approval when retrofitting and are therefore directly linked to the respective approved device.
