Tronic – mechanical spreading disc drive

With the Tronic version, the spreading discs are driven via the PTO shaft, with the spreader being protected from overload, as standard, via a PTO shaft with friction clutch. The input speed from the tractor PTO is transmitted via the central gearbox resulting in an increased spreading disc speed. This allows fertilisation at low engine revs across the maximum working width. With the mechanically driven spreaders, either 8 or 16 partwidth sections are switchable, depending on the operator terminal.

Hydro – hydraulic spreading disc drive

The Hydro version makes operation possible irrespective of the tractor’s engine revs and with different spreading disc speeds. 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. With the hydraulically-driven spreaders, between 8 and 128 part-width sections are switchable, depending on the operator terminal.

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 setting the spreading unit to different working widths and types of fertiliser, the delivery system is swivelled (concentrically) around the centre of the discs. 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

FlowCheck – for monitoring the spreader aperture

With FlowCheck, AMAZONE offers a system that continually monitors the shutter apertures against blockage or should they run empty. Whereas FlowCheck ensures that the application rate is the same on both sides or, in case of any deviation, informs the driver of a potential error. The overall application rate is monitored and regulated via the weighing system. In addition, the driver is always informed via the weigh-cells of the actual fill level in the hopper.

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

Optimised spread pattern

Normal spreading Via the adjustment of the delivery system, the feed-on point of the spreading material on to the spreading disc is changed and thus the spreading width and the lateral distribution are controlled. In addition, the working width can be set even more individually by changing the disc speed. Three-dimensional spread pattern The spreading unit has been developed using three-dimensional spread patterns so that a perfect lateral distribution of up to 54 m working widths is achieved. The large overlap zones ensure a perfect spread pattern and are significantly more consistent with regard to any the external influences such as a side wind, change in topography, humidity and changing fertiliser qualities.

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.

More precision, more efficiency!

In view of the very large working widths used now, the matching of the spread patterns is very important. Thanks to the electric delivery system adjustment on the TS spreading system, it is able to react precisely and sensitively in these cases. So even outer part-width sections can be easily controlled. In addition, due to the individual speed adjustment of the left and right hand side discs, the spreading width can be reduced from the far outside to the centre, so that, even at large working widths, long and shallow-shaped wedges and short work are optimally spread. This means part-width section control. At the simplest level of specification, 8 part-width sections can be easily actuated manually (via the operator terminal). When utilising a relevant Section Control licence on the terminal, a part-width section control of up to a maximum of 128 part width sections can be utilised.

WindControl - Calm conditions at the touch of a button

The effect of the wind on the spread pattern can be permanently monitored and automatically compensated for by WindControl. A high-frequency wind sensor mounted on the machine records both the wind speed and the wind direction and transmits this information to the job computer.
