Spreading unit technology that is well thought through – Hydraulic spreading disc drive

The hydraulic spreading disc drive allows operation irrespective of the engine speed of the tractor and the speed of the spreading discs can be varied individually. In this way, fuel is saved and a particularly comfortable and precise spreading is ensured. Also when border spreading, the spreader operates with different spreading disc speeds so that, both in the overlap range and also at the field’s border, the best possible lateral distribution can be achieved. Depending on the operator terminal, the hydraulic drive offers the switching of up to 128 part-width sections.

Hydro drive – the drive with Load-Sensing system

Spreaders with Hydro drive are fully supplied via the Load-Sensing system of the tractor. For tractors with sufficient oil supply the ISOBUS connecting cable is sufficient and the Load-Sensing system can operate the spreader at full functionality.

Hybrid drive – maximum, efficiency even on smaller tractors

For spreaders with hybrid drive, approximately two thirds of the oil capacity come from the Load-Sensing system of the tractor and the other third is reused with the aid of a second pump in the return-flow to the tractor. For this, a hydraulic pump is driven directly via the tractor’s power take off shaft. This hybrid system allows the use of smaller tractors and is, at the same time, significantly lower priced than a normal on-board hydraulic system.

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.

Soft Ballistic System pro

Mineral fertilisers require an especially gentle treatment to ensure a precise distribution and accurate transport to the crop. Fertiliser which has been already damaged in the spreader can no longer be reliably distributed.  

As a safety feature, AMAZONE Soft Ballistic System pro is integrated as standard. This means that the agitator, metering components and spreading discs are all optimally matched thus protecting the fertiliser and ensuring better yields.  

1. Gentle guidance The electrically driven star agitators in the hopper bottoms ensure an even fertiliser delivery onto the spreading discs. The slowly rotating, star shaped segments of the agitator evenly deliver the fertiliser to the relevant outlet opening. When the delivery system is adjusted, the agitator star rotates as well so that it is always perfectly positioned above the aperture. The agitator switches off automatically when the shutter slide is closed.  

2. Gentle delivery Due to the delivery system, adjustment to the throwing width and throwing direction can be regulated. In addition, the working width can be adjusted each side individually by changing the disc speed. The fertiliser is fed on centrally at a low peripheral speed resulting in little fertiliser damage. The concentric delivery system adjustment results always in a gentle treatment of the fertiliser.  

3. Gentle acceleration With a standard disc speed from 600 rpm up to 900 rpm, the AMAZONE‘s Soft Ballistic System pro gently accelerates the fertiliser. Even fertiliser types with minimal breaking strength maintain their spreading properties and provide a clean, even spread pattern.  

4. Gentle ejection With the AMAZONE Soft Ballistic System pro, as little energy as possible is given to the fertiliser for an optimum trajectory and a precise spread pattern. So, the spreading vanes are optimally adjusted to a laid-back position.

Concentric delivery system adjustment

Via the delivery system, the fertiliser is gently fed-on extremely close to the centre of the spreading disc. At this point, close to the centre of the disc; the peripheral speed is low resulting in a particularly gentle treatment of the fertiliser. For the adjustment of the spreading unit to different working widths and fertiliser types, the delivery system is swivelled electrically around the centre of the discs (concentrically). The distance between the feed-on point of the fertiliser and the centre of the disc always remains the same. The swivelling of the delivery system provides you with a wide range of possible working widths; just three sets of spreading vanes cover working widths from 15 m to 54 m.

The agitator – soft-handling and gentle

The basic function of the agitator consists in actively directing the fertiliser flow to the outlet opening, so that a constant amount of fertiliser can be applied. Any clumps of fertiliser which get through the screen are actively broken up by the guided agitator stars close to the bottom of the hopper, even at low application rates. If foreign objects reach the hopper tip and the agitator is overloaded, the electric motor reverses automatically in combination with the respective shutter and clears the fault. The perfect interplay of agitator and shutter is evident on the headland and in wedge shaped fields. As soon as a metering opening is completely closed, the agitator above it stops automatically. This protects precious fertiliser by preventing it from being crushed.


The benefits of electric agitation

  • two slow-running, fertiliser saving agitators; turning at just 60 rpm
  • which switch off automatically as soon as the shutter slide is closed, also just to the one side and independently of each other
  • that reverse automatically when blocked by a foreign object
  • active delivery of the fertiliser flow to the outlet aperture

TS spreading discs: Spreading system made from stainless steel – For a long service life

On the TS spreaders the entire spreading system is made from stainless steel providing a long service life. The vane change system enables the quick and easy change of just the spreading vane tips. The ideal solution, for example, for agricultural contractors. Between normal spreading and border spreading, different spreading vanes are activated via the so-called AutoTS system without the necessity to change spreading disc settings.

Hard-coated spreading vane

The spreading vanes are coated with a special long-lasting anti-wear protection. This is made possible by an especially hard structure to the metal. This finish is produced through a high-speed flame heating process that develops an ultra-hard coating to protect the spreading vanes against abrasive wear. Consequently, the result is a three-fold increase in lifespan. Spreading vane sets TS 1 = 15 m – max. 24 m TS 2 = 21 m – max. 36 m TS 3 = 24 m – max. 54 m

On-line calibration

The signals produced from the weighing system are used for the on-line calibration and thus enables automatic regulation of the application rate via the metering shutters. Benefits of on-line calibration: • Enter the spread rate and drive off • Reliable measuring values • Automatic regulation of the metering shutter slides

Quantity effect-free metering aperture

If it is intended to spread a constant application rate it is necessary to match the size of the metering aperture to the prevailing operational speed. Thanks to the shutter slide, this task is fulfilled very quickly and sensitively. Due to the kidney-shaped design of the metering aperture, the spread pattern remains unchanged and precise, even at varying operational speeds so that the position of the delivery system does not require any adjustment. Stage 1: Hopper aperture slightly open Stage 2: Hopper aperture half open Stage 3: Hopper aperture wide open

Electric setting motors – Ultra quick and precise!

A spreader which, due to the high application rates and operational speeds possible, explores new dimensions in terms of work rates and which, of course, needs to perform extremely precisely at the same time, requires setting motors that function extremely quickly and exactly. Especially in applications, such as the automatic on/off switching at the headland or in wedges, spreading using application maps or with the continuous on-board monitoring (ArgusTwin and WindControl), the setting motors ensure the highest level demands are met.

The brush unit – Clean transfer

The bristles of the brushes which are fitted directly to the outlet apertures reach to the upper edge of the spreading vanes so that the fertiliser is safely delivered onto the disc.

Non-sensitive spread pattern via the multi-sectional spread fan

The specific shape and angling of the spreading vanes result in a multi-spread fan from the TS spreader unit. This means that the long and short spreading vanes do not influence the spread pattern to either side and an optimum trajectory is maintained.
