Product description
Tandem manure spreader with 18 m³ capacity
The suspended tandem has a capacity of 18 m³ and carries 13.400 kg. Two vertical spreading rollers distribute the material across a width of up to 12 m, supplied by four conveyor chains with infinitely variable control.
Four chains instead of two
This is the design difference compared with the single-axle class.
Why four chain runs are needed for a 5,6 m body length: The floor moves over 13 tonnes of material. With two chains, a large area between them is left without being pulled – sticky manure remains there and is only dragged along from the edges. Four chains pull the entire floor width evenly, and the load is distributed across more chain runs.
Vertical rollers and 12 m spreading width
The two vertical rollers engage the full loading height and tear the manure apart from top to bottom. This enables them to handle straw-rich, matted and frozen-on material, which can push horizontal rollers to their limits.
Regarding spreading width: The actual width depends on the material – dry, light manure travels further than wet, heavy manure. The working width should be established using the actual material before the first load is spread; otherwise, areas may receive too much or too little.
Reinforced hydraulic rear wall with height indicator
The rear wall is supplied as standard in reinforced hydraulic form, with a height indicator.
Why the indicator is the key metering aid: The opening height of the rear wall, together with the feed speed, determines how much material reaches the rollers. Without an indicator, adjustment is a matter of guesswork and cannot be repeated reliably on the next job – with the indicator, a proven setting can be found again and recorded.
Infinitely variable feed control
The hydraulically driven chain floor can be adjusted continuously. Together with the rear wall height, this determines the application rate per hectare – the basis for nutrient management in accordance with the Fertiliser Ordinance.
Tapered body and protective equipment
- Tapered body – the material is not trapped during feeding, but flows freely towards the spreading mechanism. This prevents bridging when handling wet manure.
- Front splash guard grille supplied as standard – it keeps material thrown back away from the towing vehicle.
- Perforated viewing window in the front wall shows the fill level during operation.
- Metal covers over the wheels instead of plastic rear mudguards.
Single-line lubrication system
It centrally lubricates the spreading mechanism bearings. These bearings operate in dust, moisture and aggressive salts – regular lubrication is crucial to their service life and they are otherwise difficult to access on the machine.
Up to 22,4 m³ with silo extensions
The optional 500 mm silo extensions are fitted on top of the standard 300 mm extensions, increasing the volume to 22,4 m³.
Important: This requires removal of the spreading adapter. The trailer then becomes a dedicated transport trailer for silage and light bulk materials – it is no longer a spreader with increased capacity.
Control options
| Option | Features |
|---|---|
| standard | Control via the tractor's hydraulic spool valve |
| BASIC metering control system | Control panel for feed speed and direction, raising and lowering the slide; includes hydraulically operated slide |
| FULL metering control system | Also opens and closes deflectors and controls work lights; includes slide and hydraulic tailgate |
| ISOBUS | Data transfer, with or without control panel depending on tractor equipment |
When is ISOBUS worthwhile? When spreading according to specific field zones and recording application data – a practical way to manage the nutrient balance in accordance with the Fertiliser Ordinance.
Trailing axle as an option
The rear trailing axle with hydraulic lock reduces the turning circle and protects the grass sward. Please note: With this axle fitted, the vehicle is over 2.550 mm wide.
Additional equipment
- AT or EU type approval, including documents
- Rigid towing eye Ø 40 or rigid drawbar for upper hitching
- Hydraulic support leg, single-acting, foldable (no extra charge)
- Rear trailing axle with hydraulic lock
- 2-line compressed-air brakes with ALB
- 500 mm silo extensions for up to 22,4 m³
- Two-leaf hydraulic tailgate for boundary spreading
- BASIC or FULL metering control system
- ISOBUS data transfer system, with or without control panel
- PTO shafts and wide-angle PTO shafts in various versions
- Rear underrun protection, approved and foldable
- Warning triangle, spare wheel
Applications
Arable and mixed farms, dairy and beef cattle farms, agricultural contractors, biogas plants applying digestate, compost spreading, local authorities.
Operating notes
- Maintain a PTO speed of 1.000 rpm.
- Check the towing vehicle's drawbar load: up to 3.000 kg.
- Ensure there are sufficient hydraulic connections – the rear wall, controls and several options require additional connections.
- Establish the spreading width using the actual material before the first load.
- Plan and record the application rate in accordance with the Fertiliser Ordinance; note the rear wall height and feed speed.
- Observe distances from watercourses and buffer strips – boundary spreading is designed for this purpose.
- Never climb into the body or handle the rollers while the PTO is running.
- Before working on the spreading mechanism, disengage the PTO, stop the engine and wait for the rollers to come to a complete stop.
- Refill the lubrication system regularly and check that it is working correctly.
- Check the chains for tension and wear.
- Clean after use – salts in manure promote corrosion.
- When travelling on the road, take account of the height of 3.450 mm and width of 2.540 mm.
Frequently asked questions
What is the spreader's capacity?
18 m³, with a payload of 13.400 kg and a permitted gross weight of 21.000 kg. For on-farm use, the technically permitted weight is 25.600 kg.
How wide does it spread?
Up to 12 m. The actual width depends on the material – dry, light manure travels further than wet, heavy manure.
Why four conveyor chains?
With a body length of 5,6 m and over 13 tonnes of material, a large area between just two chains is left without being pulled, where sticky manure remains. Four chains pull the entire floor width evenly.
How do I set the application rate?
By adjusting the chain floor's infinitely variable feed speed and the opening height of the hydraulic rear wall. The height indicator makes it possible to repeat a proven setting.
Can I use the silo extensions to get 22,4 m³ capacity as a spreader?
No. The spreading adapter must be removed to fit the silo extensions – the trailer then becomes a dedicated transport trailer.
Which control system should I choose?
As standard, everything is controlled via the tractor's spool valve. BASIC provides a control panel for feed and the slide; FULL also adds deflectors and work lights. ISOBUS is the choice for variable-rate spreading with data recording.
What tractor do I need?
170 PS, a PTO running at 1.000 rpm, a hitch rated for a 3.000 kg drawbar load and several hydraulic connections. PTO shafts are available as additional equipment.
What is the lubrication system for?
The single-line system centrally lubricates the spreading mechanism bearings. They operate in dust, moisture and aggressive salts – regular lubrication is crucial to their service life.
