There are two steps involved in calibrating TRAIL-Control:
▪
Step 1: Teaching-in the middle position and end stops
In this step you teach the job computer the position of the drawbar and/or the axle in the middle,
left and right positions.
The job computer calculates all interim positions itself.
▪
Step 2: Calibrating the hydraulics of the proportional valve
Only for trailer devices with proportional valves
In this step the trailer device is automatically steered to both sides and the tensions are
measured.
The calibration runs automatically.
Teaching-in the middle position and end stops
The appearance of the screens during calibration depends upon whether your trailer device is
steered via drawbar or stud axle.
The procedure is however identical for both cases.
Phase 1 Teach-in middle position
TRAIL-Control is in manual mode.
Subsurface is not sloped. Slope sensor must not recognize any slope. Otherwise the "Slope
counter-steering" will not work properly.
1.
Switch to the "TRAIL-Control" screen:

The following screen appears:
2.
Set up the trailer device on flat ground in a line behind the tractor. Drive straight for a few meters
until the tracks of the field sprayer run precisely into the tracks of the tractor.
or
- set the middle position with the function keys.
3.
Stop the tractor as soon as the field sprayer is exactly in line behind the tractor.
4.
- Call up middle position calibration.
