6. Change the four–wheel drive engagement time value with the up or down
arrow button.
The value can be chosen between 0 and 30 seconds.
When the value is set to 0 seconds the driving start automatics is
disengaged.
The value is automatically saved when you deactivate the selected field by
moving the navigation box to another parameter or by pressing the ESC
button.
With a short press of the ESC button you can return to the menu 2. A long press
of the ESC button returns to the previously active drive display.

Anti-slip regulation
3.8.21.1 Anti-slip regulation
The anti-slip regulation (ASR) assists in maintaining the optimal wheel slipping on
different surfaces, so that traction is as efficient as possible. When driving in the
field, a certain slipping percentage at a certain driving speed is required in order
to achieve the optimal traction efficiency. When the wheels slip, they dig into the
ground, the tires' contact surface with the ground increases and traction
improves. The optimal slipping percentage depends on the driving speed, surface
quality and type and the load the tractor imposes on the surface. The ASR makes
the driving more stable and assists on slippery surfaces by controlling the engine
power and tractor speed. The ASR is available when the Auto1 mode is selected.
You can activate and set the ASR in the tractor terminal. There are five setting
values available, from which the higher values allow for a higher slipping
percentage. You can use any of the setting values on any surface type,
depending on the work at hand and your preference. If the slipping percentage is
not the best possible for a certain task, you can change the value or deactivate
the ASR at any time. If you do not know which setting to use, we recommend that
you select setting 5. The following table provides examples for selecting the
setting depending on surfaces and tasks.

When driving on soft surfaces, reducing the tire pressure and increasing the load
with ballast weights can also make driving more efficient. This increases the tires'
