Second drive through
In this phase, you will need to apply the product over the area where you applied with the first track at a 90° angle. You then have to check if the sprayer is switching on too early or too late. In doing so, it is important that you drive at a constant speed and remember this speed.
In this phase, you will require the help of one or two people. These people will observe the driving and behaviour of the sprayer, and mark out the application borders.
They should be appropriately trained and warned of the potential dangers.
The illustration below shows where the observers must stand and the objectives that they must achieve.

Procedure
- þ
- The tank is filled with clear water.
- þ
- The observers should stand at a safe distance from the boom of the sprayer.
- þ
- Navigation is started. The first drive record is loaded.
- þ
- SECTION-Control should be in automatic mode.
- 1.
- Position the sprayer at a distance of approx. 100 meter from, and an angle of 90° to the applied area.
- 2.
- Drive at a constant speed (e.g.: 8 km/h) over the area that has already been applied. Remember the speed at which you were driving. Apply the water as you do so.
- 3.
- The observers must stand on the previously marked boundaries of the applied area at a safe distance from the boom.
- 4.
- The observers must observe the points at which the sprayer stops and starts spraying, as it passes along the already applied points.
- ⇨
- You will now know how the sprayer behaves when travelling along an area where the product has been already applied.
You may wish to repeat this process several times in order to ensure better accuracy of the results.
