Headland management for tractors, field sprayers, mowers and harvesters

Description:
Headland management allows functions to be combined in the vehicle and activated together at the touch of a button to simplify turning manoeuvres during field work. All functions can be activated and deactivated individually for each vehicle via a GUI in order to achieve ideal adaptation to the work being carried out.

Headland management must be added to the respective vehicle as a one-off configuration in the shop or in the workshop before use. The cost for this is 3000$.
It can be activated and deactivated in the vehicle. Various buttons can also be configured for activation and deactivation.

Functions included:
- Reduce speed (cruise control) and raise again, reactivate cruise control if it was previously active
- Raise lowered implements and lower them again, optionally raise front implements before raising rear implements
- Turn the plough, single-stage or two-stage (via the centre position)
- Raise and change track markers
- Change sides with crab steering activated
- Switch off PTO shaft(s) and hydraulics and switch on again
- Warning tone when headland mode is activated
- On/off switch: The headland management can be switched on and off. This prevents accidental activation during transfer to the work site and improves road safety.
- Automatic headland management: Automatic activation of headland mode when the headland is reached. Optional return to field mode after completing the 180° turn.
- Option to temporarily deactivate headland automatic headland by pressing a button
- Contour guidance: Automatic control along the field boundary or along the cultivated area
- The configuration is saved and restored for each device type

With existing EnhancedVehicle (FS25_EnhancedVehicle):
- Deactivate and reactivate GPS lane guidance, optionally trigger the turning function
- Release and reset active differential locks
- Use of EV headland detection if it has been activated
