Introduction
Chapter 1 –
Correct auto steering tuning is required to ensure the vehicle
approaches and follows guidelines in a smooth and consistent manner.
Tuning should only be carried out if auto steering performance is
unsatisfactory.
Note
: Tuning should be carried out in a clear area away from high
voltage power lines and large metal objects. Allow enough space to
drive in a straight line for a minimum of 100 meters and enough room
to drive in complete circles. Tuning should be carried out at a speed
matching the speed of the operations planned.
The following factors can affect the performance of the steering
system:

Tyre size and number

Implement size, shape and loading

Vehicle speed

Terrain and soil condition
Tuning the vehicle is a real world application that is best performed in
actual working conditions. For example:

On soft ground with the implement fitted and engaged in work.

Hydraulic fans running if it is a seeder.

For self-propelled sprayers; have boom folded out with half a tank
of water.

For windrower, combines etc, have the front fitted and machine
running.
All these factors can severely affect steering performance and tuning
ability.
Note
: The steering response of each vehicle will behave in a slightly
different manner. Two vehicles of the same make and type may
require different settings for optimal performance.
