ZG-TS trailed spreader

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. The spreader also operates at different spreading disc speeds in border spreading, meaning that the best possible lateral distribution can be achieved in the overlap areas as well as at the field boundary.

The benefits

• The side-independent regulation of the spreading disc speed permits even more precise spreading on wedgeshaped fields. Up to 128 part-width sections are possible in combination with SectionControl. 
• In combination with WindControl, side-independent regulation enables windy conditions to be compensated for 
• Pressure filter as standard

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.

• Change between load sensing and an oil flow and return as standard

Hydro drive with oil supply exclusively from the tractor
- Oil requirement with steering axle max. 130 l/min
- Oil requirement without steering axle max. 105 l/min

“The consistently stable speed of the discs and also, above all, the possibility of different disc speeds is a dream. You only come to know and appreciate the benefits offered by the hydraulic system when you have used it”
(“profi”– Spreading units in practice “Hydraulic or mechanical”· 06/2017)

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.

• Full functionality with a lower oil requirement
• Without a complex on-board hydraulic system

4 decisive advantages with SBS pro

Mineral fertilisers require particularly gentle treatment to ensure precise distribution and transport out to the crop over the total working width. Fertiliser, which has been damaged whilst going through the spreader, will not be precisely distributed.

The Soft Ballistic System pro is integrated as standard as a safety feature. The agitator, metering components and spreading discs are optimally tailored to each other. This protects the fertiliser and secures your 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 handling of the fertiliser.
3. Gentle acceleration: 
   With a standard disc speed from 600 rpm to 900 rpm, the 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 aid of the Soft Ballistic System, the fertiliser is provided with the energy required for the optimum trajectory and a precise spread pattern. So, the spreading vanes are optimally adjusted to a laid-back position.

Characteristics of the TS spreading system

Delivery system adjustment of the TS spreading system
1) Intelligent agitator for maximum fertiliser protection
2) Electric setting motor for rotating the delivery system
3) Delivery system for implementing the Section Control, HeadlandControl and WindControl functions ArgusTwin
4) Electric setting motor for a precise fertiliser metering with application rates from 3 kg/min to 650 kg/min

5) Electric setting motor for adjustment of the carrier vane
6) AutoTS gearbox, the heart of the integrated border spreading system
7) Comfortable changeover between border and normal spreading by moving the carrier vane
8) Short border spreading vane for sharp side, border and water course spreading
9) Long normal spreading vane for high throwing widths and double overlap, even at a working width of 36 m

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

"A 12V motor drives the agitator which rotates at 60 rpm. It switches off when the shutter is closed and it reverses as soon as a foreign object blocks the agitator."

Concentric delivery system adjustment

The fertiliser is applied via the delivery system extremely close to the centre of the spreading discs in a granule-protecting flow. The peripheral speeds are low near the centre of the discs, thus ensuring very 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. A working width range from 15 m to 54 m is covered by just three sets of spreading vanes.

All TS spreading systems with electric delivery system adjustment are suitable for the ArgusTwin spread pattern monitoring system.

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 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.

If it is intended to spread a constant application rate it is necessary to match the size of the aperture to the prevailing forward 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 forward speeds so that the position of the delivery system does not require any adjustment.

Spreading system made from stainless steel – for a long service life

On the TS spreaders, the entire spreading system is made from stainless steel ensuring a long service life.

The different spreading vane sets can be quickly and easily exchanged using an interchangeable system. 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-metal-coated spreading vanes
The spreading vanes are coated with a special long-lasting anti-wear protection. Consequently, the result is a three-fold increase in lifespan.

Optimum working width ranges of the spreading vane sets, depending on the fertiliser being spread:
TS 10 = 15 m – max. 27 m
TS 20 = 21 m – max. 33 m
TS 30 = 24 m – max. 54 m

1. The integrated AutoTS border spreading system is activated electrically.

“For different working widths it is then just a case of interchanging the spreading vane set – a very comfortable solution.”

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.

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 pattern of the fertiliser from the long and short spreading vanes do not influence each other and so an optimum trajectory is maintained.

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.
