Border spreading systems

Side spreading (yield oriented setting)

The adjacent field is also in a crop. In this instance, the small amount of fertiliser being thrown beyond the field’s border can be tolerated. The fertiliser distribution inside the field is maintained so that there is still about 80 % of the actual spread rate even at the field’s edge.

Boundary spreading (environmentally oriented setting)

If the field is positioned next to a road or against a cycle path, no fertiliser should be thrown beyond the field border. In order to avoid over-fertilisation inside the field, the spread rate on the border side needs to be reduced. This results in slight under-fertilisation at the extreme of the field boundary. The border spreading procedure complies with the requirements of the Fertiliser Directive.

Water course spreading (environmentally oriented setting)

In cases where a water course is situated directly at the field’s edge, the fertiliser environmental legislation prescribes the maintenance of either a distance of one metre with the aid of a border spreading device, or as much as three metres when not using a border spreading device. In order to prevent over-fertilisation on the inside of the field, the spread rate from the side of the spreader towards the border again has to be reduced.

Border spreading with the border spread deflector

If the first tramline is situated at the field’s edge, border spreading (environmentally-orientated adjustment) is then achieved by utilising the half-side shut-off of the spread fan. No fertiliser is thrown beyond the field boundary and optimum fertilisation is maintained inside the field.

Bed spreading with bed spreading deflector to both sides

AMAZONE offers the bed spreading deflector for spreading special crops in beds on the left and right of the tramline. This keeps the tramline almost completely free of fertiliser.

AutoTS – comfortable and precise Lateral distribution right up to the field’s border

The disc-integrated AutoTS border spreading system enables the activation of the different border spreading procedures – side, border or watercourse spreading – comfortably via the Terminal in the tractor cab, irrespective of which side.

The ingenious operating principle of AutoTS

An actuator turns the delivery vane by approx. 10 °, so that the fertiliser is guided via the shorter border spreading vane in border and water course spreading. The combination of speed and using the shorter vane means that the fertiliser is thrown a considerably shorter distance without stressing it mechanically.

Higher yields in the boundary zone with AutoTS and ClickTS

The AutoTS and ClickTS border spreading systems make it possible for the operator to reliably generate a very steep cut-off to the border spread pattern and thus create perfect growing conditions close to the field boundary. As a result, a significant increase in yield compared to previous boundary spreading systems is possible.

The AutoTS spreading system provides automatic rate reduction when border spreading. The rate can be changed in freely selectable percentage steps. As the two spreading discs can be operated independently of each other, an overall or an individual rate change can be set.


AutoTS border spreading system (green line)

  1. The throwing distance of the fertiliser is restricted by a shorter spreading vane.
  2. The fertiliser remains undamaged and is optimally distributed up to the field boundary.
  3. Due to the reduced throwing speed of the fertiliser, only a few granules fall beyond the field boundary.


Conventional border spreading systems (red line)

  1. The mechanical deflection of the fertiliser causes damage to the granules which then drop next to the tramline.
  2. This quantity of damaged fertiliser is then missing from the boundary zone area resulting in under-fertilisation.
  3. Not all the fertiliser granules are mechanically deflected, so that some are spread well beyond the field boundary.

In addition to having the AutoTS system on both sides which is remote-controlled from the cab, there is also the option of having the one-sided AutoTS and the manual changeover of ClickTS on the other disc. ClickTS is also possible on both sides.

Border spread deflector

In the case of operation to spread directly from the field side into the inner field, the border spread deflector is available. When the border spread deflector is swivelled into work then spreading is carried out only with the field side spreading disc so that any fertiliser is deflected in such a way that it is thrown into the field and only behind the tractor, however, and not beyond the border. The border spread deflector can be utilised to both the left or right hand side. The actuation of the border spread deflector is carried out either manually or, as option, hydraulically from the tractor seat. When swivelled out of work, the border spread deflector has no influence on the normal spreading.

Bed spreading deflector

For spreading beds to either side of the tractor, the bed spreading deflector provides the optimum fertiliser distribution without spreading any material behind the tractor. For optimising the fertiliser distribution, the telescopic end pieces on the bed spreading deflector can be adjusted to suit, depending on working width and fertiliser type. The bed spreading deflector can be used on one side or both sides. Just like the border spread deflector, the bed spreading deflector is actuated manually, or, as an option, hydraulically from the tractor seat. If the bed spreading deflector is swivelled up out of the way, then the spreader can be utilised as usual for arable farming.

The problem: Over- and under-fertilisation on the headland

Different fertilisers have different switch-on and switch-off points. In practice, the switch-off points are usually only achieved when the tractor is turning on the headland. The arc of spread behind the tractor swings round to the side creating areas that are either over- or under-fertilised.

HeadLandControl

The solution: HeadlandControl

When HeadlandControl is activated, the throwing width and spread rate are increased on the inner field side, so that 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 fan, causes the part-width sections to be switched off from the outside to the inside when entering the headland. Over- and under-fertilised zones on the headland are subsequently avoided.

Switch-off time on the headland: Without HeadlandControl

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

Result: Over- and under-fertilised zones are created

Switch-off time on the headland: With HeadlandControl

  • HeadlandControl means that the spreader continues to apply fertiliser to the crop when it is on the headland
  • The tractor can follow the wheel tracks of the sprayer

Result: Uniform crops across the headland
