HeadlandControl – optimum lateral distribution on the headland

The problem: over- and under-fertilization on the headland

Different fertilizers have different switch-on and switch-off points. In practice, the switch-off points are usually only activated when the tractor is turning on the headland. The arc of spread behind the tractor and around to the side creates areas that are either over- or under-fertilized.

Switch-off time on the headland: Without Headland Control

1. Spreader switches off too late and is already turning
2. Tractor would have to drive beyond the headland tramline

Result: Over- and under-fertilized areas on the headland

1. Over-fertilisation (dark-green)
2. Under-fertilisation (white)
3. Standard headland
4. Inner throwing distance without HeadlandControl

The solution: HeadlandControl

When Headland Control is activated, the throwing width and spread rate are increased on the field side, so the switch-off point is moved towards the inside of the field. Furthermore, the new part width section control, which is now adapted to the shape of the spread pattern, causes the part width sections to be switched off from the outside to the inside when entering the headland. This prevents over- and under-fertilized zones on the headland.

With HeadlandControl

• Headland Control means that the spreader continues to apply fertilizer to the crop when it is on the headland
• The tractor can follow the wheel tracks of the crop protection sprayer

Result: uniform crops across the entire headland

1. Optimum lateral distribution on the headland
2. Switch-off point moved
3. Extended headland
4. Inner throwing distance with HeadlandControl
