Effective and precise – spread only where the fertiliser will benefit plants

Side spreading (yield-oriented) with Limiter V or V⁺
The adjacent field is an area which is used agriculturally. In this case it is tolerable for a small quantity of fertiliser to be thrown over the field border. The full target rate is applied right up to the field boundary.

Border spreading (environmentally oriented) with Limiter V or V⁺
If the field is next to a road or a cycle path, no fertiliser may be thrown beyond the field boundary. In this case, the throwing distance is adjusted in combination with the shutter slide.

Water course spreading (environmentally oriented) with Limiter V or V⁺
If there is a body of water directly at the edge of the field, a defined distance to the water must be maintained when fertilising according to the fertiliser regulations. For this purpose, the throwing distance is further reduced in combination with the shutter slide.

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

Bed spreading via bed spreading deflector on both sides
AMAZONE offers the bed spreading deflector for spreading special crops in beds on the left and right of the tramline. It keeps the track virtually free from fertiliser. The bed spreading deflector is actuated manually or, as an option, hydraulically from the tractor cab.

Electrically adjustable Limiter V⁺
The sensitive electrical adjustment of the Limiter V⁺ border spreading device to the respective field boundary enables comfortable switching between field-side, border and water course spreading from the tractor cab during fertiliser application. Due to the design of the Limiter V⁺ being open at the bottom, this can be swivelled down gradually from above into the spread fan diverting what is going towards the field’s border.

1. With just a slight lowering of the Limiter V⁺ only the fertiliser flow of the long vane is deflected.
2. If the Limiter V⁺ is lowered further, the fertiliser flow from both spreading vanes is deflected.
3. In the completely lowered position, lamella block provides an accurate spread pattern towards the field’s border.

For spreading adjacent to fields, roads or water courses, the ZA-V can also be equipped with the Limiter V⁺ border spreading device. The border spreading device can then be smoothly lowered into the fertiliser flow at differing heights. The swivelling adjustment around the centre of the spreading disc sets the Limiter V⁺ to the different working widths and fertiliser types. This ensures an accurate spread pattern at the border.

3. Border and water course spreading

Hydraulically-actuated Limiter V

The hydraulically actuated Limiter V border spreading system is available for side, border and water course spreading. Prior to spreading, the recommended working height of the Limiter V is fixed via a pin, depending on the border situation. Around the field’s edge, the Limiter V can then be hydraulically lowered to that pre-selected position and raised again in the field.

For the case of spreading directly from the field side into the inner field, the border spread deflector is available.  When the border spread deflector is swivelled down, spreading is carried out only with the field side spreading disc, so that any fertiliser is deflected in such a way that it is only thrown behind the tractor and into the field, but not beyond the border. The border spread deflector can be utilised on both the left and right hand side. The border spread deflector is actuated manually or, as an option, hydraulically from the tractor cab. When swivelled up, the border spread deflector has no influence on normal spreading.

Field trials prove the best border spreading results
The aim of the field trial was to demonstrate that border spreading systems and equipment not only offer ecological benefits but also have a great influence on the potential yield in the field boundary area. Precise technology is required to spread the full rate of fertiliser right up to the field boundary as well as to avoid any fertiliser losses outside the field boundary.

The Limiter provides a simple and precise introduction to border spreading systems. Especially with the Limiter V⁺ electric border spreading device, it is possible to harness the full potential of the field by responding to changing border situations from the tractor cab.

Key statements of the trial

• “A wider working width or smaller field size increases the size of the return on a boundary spreading system.” 
• “All border spreading systems can significantly reduce the amount of fertiliser thrown outside the boundary.” 
• “With the ‘Lamella block’ and ‘Hydro’ systems, the percentage outside the field boundary is reduced to only 2.5 %.”
