Product description
Tandem rear tipper with 830-mm extensions
The suspended two-axle trailer carries 14.430 kg and has a capacity of 23 m³ without extensions. With the 830-mm extensions, capacity increases to 34,3 m³ – at an overall height of 3.900 mm.
The 830-mm extensions with folding mesh front extension
This is what makes this version special. The extensions are made from 2-mm sheet metal, while the front extension is a folding grille with a mesh size of 30 × 30 mm.
Why a grille at the front is useful:
- View into the body while driving – otherwise difficult at a body height of 2,33 m.
- Airflow during loading – when being overloaded by a forage harvester, displaced air escapes instead of pushing the material back out.
- Folding design – for passing through height-restricted openings and for loading from the front.
Please note: With the extensions fitted, the trailer is 3.900 mm high – just below the 4-metre limit, above which transport requires a permit. Check farm entrances, silo passages and underpasses in advance.
14.430 kg at 34,3 m³
This gives a calculated limit of around 0,42 t/m³.
- Wood chips and green waste (0,2 – 0,3 t/m³) – here, volume is the limiting factor. This is the intended application.
- Maize silage (0,6 – 0,7 t/m³) – the payload limit is reached well before the body is full.
- Without extensions, at 23 m³ the limit is 0,63 t/m³ – suitable for grain and maize.
BOGIE chassis as an option – available only on this model
Among the models in this range, the T700 is the only one available with BOGIE suspension and hydraulic locking of the rear axle.
What a BOGIE chassis does: It links both axles via a pivoting mechanism. Both axles remain in contact with the ground, even over severe unevenness – a crucial difference on farm tracks, at silo edges and on unpaved terrain. The load is distributed evenly instead of overloading one axle.
Please note: The BOGIE chassis is not available in the CoC version.
550/60-22,5 – the widest tyres in the range
The T700 comes as standard with significantly wider tyres than the XL version, which has 385/65 R 22,5 tyres.
Why this matters: Wide tyres distribute the load over a larger area, reducing ground pressure and protecting farm tracks and grassland. Combined with the BOGIE chassis, this makes the trailer suitable for difficult ground conditions.
55° tipping angle
Five degrees more than most agricultural tippers. With damp material, silage and sticky soils, this can determine whether the body empties completely.
Drum brakes 406 × 140 mm
The most powerful brakes in the range – the XL version has 406 × 120 mm brakes.
Why this matters: The trailer weighs 6,6 tonnes empty and 21 tonnes when loaded – more than three times as much. ALB and ALB Premium are available as options; ALB is included in the package for EU type approval in any case.
Drop sheets for silage harvesting
Three sets measuring 2,3 m, 2,3 m and 1,8 m are available as optional equipment – only with the 830-mm extensions.
What they are for: When being overloaded by a forage harvester, the material falls from a height of several metres. The sheets slow its fall – preventing chopped material from being blown over the side walls and distributing it more evenly in the body.
Universal drawbar for high and low hitching
The trailer is compatible with tractors with a drawbar hitch at frame height as well as those with a hitch coupling – no conversion required. A K80 ball coupling is available as optional equipment.
Self-steering axle as an alternative
The rear self-steering axle with hydraulic locking reduces the turning circle and protects the grass sward. Please note: The axles are longer than the standard axles, and additional hydraulic connections are required.
Self-steering axle or BOGIE? The self-steering axle helps with manoeuvring and on grassland; the BOGIE chassis is better for severe unevenness and load-bearing capacity. They are not designed to be used together.
Grain chute and viewing window
- The grain chute in the rear wall allows grain to be discharged in a controlled manner without opening the entire tailgate.
- The viewing window in the front wall, made from grille and sheet metal panel, shows the fill level while driving.
Approval
| Approval route | Permissible gross weight | Payload |

Operating notes
- Confirm the approval route before ordering – there is a 3.000 kg difference between individual approval and EU type approval.
- Check the overall height: With the extensions fitted, the trailer is 3.900 mm high.
- Check the towing vehicle's drawbar load: up to 3.000 kg.
- Tip on level, firm ground – with a stroke length of 2.990 mm, the centre of gravity is high.
- Do not raise the body beneath overhead power lines.
- Before tipping, check that the tailgate can open freely.
- After unloading, check that the body is empty.
- The technically permissible 24.000 kg applies only to on-site use.
- The BOGIE chassis is not available in the CoC version.
- Drop sheets can only be used with the 830-mm extensions.
- Retighten the wheel nuts after the first few hours of operation and regularly thereafter.
Frequently asked questions
What is the tipper's capacity?
23 m³ without extensions and 34,3 m³ with the optional 830-mm extensions.
How much can it carry?
14.430 kg at a permissible gross weight of 21.000 kg. A technically permissible 24.000 kg is allowed for on-site use, and 18.000 kg with EU type approval.
What is special about the extensions?
The front extension consists of a folding grille with a mesh size of 30 × 30 mm. It provides a view into the body, lets displaced air escape during loading and folds down for low-clearance passages.
What is a BOGIE chassis?
A pivoting mechanism that links both axles. It keeps both axles in contact with the ground, even over severe unevenness, and distributes the load evenly. It is not available in the CoC version.
How high is the trailer with the extensions fitted?
3.900 mm – just below the 4-metre limit. Check farm entrances, silo passages and underpasses in advance.
What are the drop sheets for?
When being overloaded by a forage harvester, the material falls from a height of several metres. The sheets slow its fall, prevent material from being blown over the side walls and distribute the chopped material more evenly.
What tractor do I need?
124,8 PS or 91,7 kW and a coupling rated for a drawbar load of 3.000 kg. Tipping requires 40 litres of oil at 200 bar.
BOGIE or self-steering axle?
The self-steering axle helps with manoeuvring and protects the grass sward; the BOGIE chassis is better for severe unevenness and uneven load distribution. They are not designed to be used together.
