Product description
The large push-off trailer – up to 61 m³
The tridem unloads without tipping, using a hydraulically operated moving wall. With a 9,7 m body length, it holds 49 m³, or up to 61,2 m³ with extensions – with a payload of 20,7 tonnes.
Why push off instead of tipping
- No risk of tipping over. When tipping, the load is several metres above the axle; on soft or uneven ground, the trailer can overturn. When pushing off, the centre of gravity stays low.
- Unload in sheds and beneath overhead lines. A tipping trailer needs twice its height to tip. The push-off trailer remains at 3.490 mm.
- Controlled unloading. The moving wall can be advanced precisely – material is spread while driving, rather than unloaded in a heap.
- Complete emptying. Sticky material – wet silage, damp compost – sticks when tipping. The moving wall pushes it out.
49 m³ – one third more than the standard version
This is the key feature of the XL: 1.380 mm more body length with the same width and side wall height.
| Body configuration | Volume | Overall height |
|---|---|---|
| without extensions | 49 m³ | 3.490 mm |
| 400 mm extensions | 58,7 m³ | under 4 m |
| 500 mm extensions | 61,2 m³ | over 4 m (except with 445/65 R 22,5 tyres) |
The 4-metre limit is crucial. Above an overall height of 4 m, transport on public roads requires a permit – and many farm entrances, silage clamp passages and underpasses are lower. The manufacturer expressly states that the 400 mm extensions keep the trailer under 4 m.
When volume matters more than payload
With a payload of 20,7 tonnes and a volume of 61 m³, the calculated limit is around 0,34 t/m³.
- Wood chips (0,2 – 0,3 t/m³) – here, volume is the limiting factor, and the XL comes into its own.
- Grass silage (0,5 – 0,7 t/m³) – here, the payload limit is reached first.
- Maize silage, compost and grape marc fall between these.
Rule of thumb: If you mainly transport light material, the XL lets you carry genuinely larger loads. If you transport heavy silage, the standard version with its 36,7 m³ is more economical.
Forced steering without tractor steering system
The mechanical-hydraulic forced steering to DIN ISO 26402 operates on both sides and works without the tractor's steering system.
Why this is essential with an overall length of 12 m: Three fixed axles close together scrub sideways when cornering – with this wheelbase, the trailer would be difficult to manoeuvre around the farmyard. The system includes a hand pump for filling the system and four pressure gauges.
5 mm floor
The moving wall pulls the entire load across the floor – at 20,7 tonnes and a length of 9,7 m, this creates enormous friction forces. The floor is both a wear part and a load-bearing component here.
Tension cables included as standard
Unlike the standard version, they are included here as standard equipment. They keep the body in shape when heavily loaded – an important consideration with a length of 9,7 m and 2 m side walls.
Perforated viewing window with PLEXI pane
Check inside the body without getting out. With a body length of almost ten metres, this is the only practical way to check the fill level while driving.

Operating notes
- Confirm the approval route before ordering.
- Check the overall height: With 500 mm extensions, the trailer exceeds 4 m – except with the standard 445/65 R 22,5 tyres.
- Check the towing vehicle's drawbar load: up to 3.000 kg.
- The push-off system requires 80 litres of oil at 200 bar.
- Check the forced steering regularly; the four pressure gauges indicate the system condition.
- Fill and bleed the system using the hand pump if the pressure drops.
- Before pushing off, check that the tailgate can open freely and that nobody is standing behind the trailer.
- Check the floor regularly for wear.
- With an overall length of 12 m, check access routes and turning space in advance.
- Retighten the wheel nuts after the first few hours of operation and regularly thereafter.
Frequently asked questions
How much does the trailer hold?
49 m³ without extensions, 58,7 m³ with 400 mm extensions and 61,2 m³ with 500 mm extensions.
How much can it carry?
20.730 kg with a permissible gross weight of 33.000 kg. For on-site use, a technical gross weight of 36.000 kg is permitted; with EU type approval, it is 30.000 kg.
Does the trailer stay under 4 m high?
Yes, without extensions and with the 400 mm extensions. With 500 mm extensions, it exceeds 4 m – except with the standard 445/65 R 22,5 tyres.
What materials make the XL version worthwhile?
Light materials. With 61 m³ and a payload of 20,7 t, the calculated limit is around 0,34 t/m³ – wood chips and biomass make full use of the volume, while heavy grass silage reaches the payload limit first.
What are the advantages over a tipping trailer?
No risk of tipping over on soft or uneven ground, unloading in sheds and beneath overhead lines without extra clearance, controlled spreading while driving, and complete emptying even with sticky material.
Does the forced steering need to be connected to the tractor?
No. The mechanical-hydraulic forced steering to DIN ISO 26402 works without the tractor's steering system.
What tractor do I need?
220 PS, a hitch suitable for a 3.000 kg drawbar load, and 80 litres of oil at 200 bar for the push-off system.
Why is the floor 5 mm thick?
The moving wall pulls the entire load across the floor – at 20,7 tonnes and a length of 9,7 m, this creates enormous friction forces.
