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.
