Drive concept.

Built to work.

Vehicle concept.

The Unimog’s operational safety features and robust design have established it as a versatile implement carrier for professionals. That’s because the Mercedes-Benz Unimog was developed specifically for professionals. In conjunction with reputable implement manufacturers/bodybuilders, combined with input from our Unimog partners, the Unimog’s continuous development has created a flexible platform that is unparalleled. Despite its relatively compact design the Unimog can undertake any number of tasks. Operating the Unimog is made easier, safer and more efficient through the use of the removable multifunction joystick.

Full power: mechanical implement drives.

The optional engine-powered PTO drives the power hydraulics, but it can also be used to run powerful implements in combination with a hydrostatic drive. The gearbox PTO with its standardised flange allows fitment of hydraulic pumps to operate cranes and elevating work platforms. Output speed and rotational direction are identical to the engine speed and rotational direction.


Front-attached implements requiring a great deal of power are run off the front PTO shaft which takes its power directly from the drivetrain of the engine. It is oil-cooled as a standard feature and with a 1¾” splined shaft, it allows for a high torque transfer whilst also ensuring a very high degree of efficiency – especially in continuous operation.

Even during gear changes, the flow of power is uninterrupted, plus, the coupling can even be actuated under load. The power take-off shaft’s rotational speed (up to 1000 rpm) can be simply and precisely set. It is thus possible to work both comfortably and powerfully at the same time. The front power take-off shaft delivers up to 160 kW while at the mechanical rear power take-off shaft, as much as 220 kW is readily available.

Electrical dives.

Simply plug in – job done.

Four standard interfaces in the cab and on the outside allow electrical consumers to be connected or implements to be operated without the need for any cabling work. The on-board 24 V electrical system is supplied by a three-phase 150 A alternator. The parametrisable on-board electronics run via the CAN bus and therefore make it easy to change settings such as: limiting the engine speed to protect mechanically driven implements; activating the drive-away lock when the supports are deployed; or restricting the speed.


A master of hard work.

Nothing can unsettle a Unimog.

With its tried-and-tested chassis concept which is based on the robust sub-frame, the Unimog can master even the biggest of challenges in tough everyday operations. Characteristic features are permanent all-wheel drive, great ground clearance resulting from the use of portal axles, high ride comfort, excellent axle articulation and differential locks on both axles. The implement carrier’s single tyres, Tirecontrol Plus central tyre inflation system and optimal weight distribution mean it is in its element, even off the beaten track – and with a speed of up to 89 km/h it’s also great on the road.


Even more agile thanks to all-wheel steering.

The optional rear-axle auxiliary steering available on the models from the U 423 to the U 530 serves to reduce the turning circle by a further 20 percent. Accordingly, the vehicle’s manoeuvrability also benefits from this in operations during which every centimetre counts. Four types of steering are available: normal steering, all-wheel steering, manual steering and offset track steering (so-called “crab steering”). This variant can help counteract downhill force. When reversing, only the rear wheels steer.


Top performing technology with power as standard.

Powerful transmission.

In the Unimog, the fully synchronised electro-pneumatic transmission with its eight forward and six reverse gears provides the tractive power. Unimog is characterised by reliability, robustness and efficiency. And the synchronised Electronic Quick Reverse feature makes it easier to change direction quickly, for instance, during snow-clearing or manoeuvring. There is also the option of a forward-reverse switch which can be integrated into the multifunction joystick.

Total control, total relief: automated shifting.

Two drive programs help reduce the driver’s workload: in automatic mode “A” – whilst taking into account the load, accelerator position, engine operation, climbs/inclines and the engine brake – the drive program handles gear changes and clutch operation entirely. However, if it becomes necessary for the driver to manually change gear using the multifunction lever, this is also possible.

Complete control is offered by the “M” drive program (manual). Here, gear selection is also made using the multifunction lever. The driver determines the gear and the clutch operation occurs automatically.

Made for everyday operations.

The Unimog implement carrier is a workhorse. And the fully synchronous manual transmission with eight forwards and six (or optionally eight) reverse gears is true proof of that. The fine graduation in the lower gears allows easier individual adjustment of the speed to the current operations. Rapid changing of direction and rocking free are no problem at all thanks to the truck’s synchronised reversing gears: it is possible to shift directly between forwards and reverse gears. The low positioning and modular design are conducive to a low vehicle centre of gravity and low transfer of engine vibrations.

Proven top-level performance.

There are three variants of transmission-driven power take-off available. For example, the rapid transmission power take-off with 4-hole flange can be used to drive hydraulic pumps. The rotational speed and direction of the power take-off are the same as the engine speed and its direction of rotation. For implement control from outside the cab, a remote control is also available. Programming of the maximum rotational speed prevents overstepping the permissible upper rotational speed limit.

Equally as powerful is the transmission-driven power take-off with 6-hole flange. For applications whereby a very high power take-up is required, such as for fire service pumps, the third variety – also with standardised 6-hole flange – offers an optimal solution. With a nominal engine speed of 2200 rpm, a working speed of up to 3606 rpm can be attained. Here, too, a remote control for use outside the vehicle is also available.

Hydraulic systems.

Power meets precision.

Fully proportional working hydraulics.

Excellent hydraulic performance which is more precise than ever before: the working hydraulics control implements precisely and without jerky movements. With this in mind, the fully proportional hydraulics system increases efficiency in daily operations. The working hydraulics allow for two positioning movements to be carried out at the same time – simply by using the multifunction joystick. Further functions can be set via the steering wheel buttons. Larger trailer tipping cylinders can also be filled with up to 30 litres of hydraulic oil to draw on as required.

The four-cell working hydraulics and communal hydraulics in accordance with the EN 15431 norm that are used on the implement carrier feature two circuits. Circuit I controls up to eight implement adjustments with a system pressure of 200 bar (32 l/min) over two to four dual-operation valves; alternatively it drives hydraulic motors at the lower output range. When combined, circuits I and II (32 plus 55 l/min) can now mobilise an impressive 35 kW at up to 240 bar. Positioning movements and the powering of hydraulic motors can be carried out independently of one another.

Load-sensing hydraulics with 110 l/min, 240 bar.

The load-sensing system is a hydraulic control mechanism in which the pressure and/or flow volume of the hydraulic pump is/are adapted to the conditions required by the consumers. In regular hydraulic circuits, the flow volume to the motor is throttled by means of pressure restriction valves or pressure control valves. The hydraulic pump always supplies the full power, even in the case of the flow volume being throttled. In some cases, this can cause high power losses. The load-sensing system, however, ensures that the pump only supplies the flow volume which is currently required for all active consumers.

More power, more efficiency: the VarioPower® power hydraulics.

Two circuits, both with 125 l hydraulic oil through-flow per minute and 280 bar pressure: the VarioPower® power hydraulics don’t shy away from work, however hard it may be. Regardless of whether several different tasks have to be carried out simultaneously or a single job requires high output. The two open circuits III and IV have the same high through-flow of 125 l/min, system pressure of 280 bar and a maximum output of 58 kW. Operation via the steering wheel buttons of the multifunction steering wheel means it is particularly easy to control. All the settings are displayed in the new instrument cluster.

Engine and emissions

Economical. Powerful. Environmentally friendly.

The economical engine.

The Unimog implement carrier is equipped with the most modern Mercedes-Benz BlueTec 6 technology. Tested in large-scale series production, the Euro VI engine generation sets new standards for its class and takes no half-measures where conserving the environment, economic efficiency and top performance are concerned. The 4 and 6-cylinder engines ranging from 115 to 220 kW are especially easy to maintain, economical, smooth-running and powerful. They have high torque of up to 1200 Nm as well as good results for exhaust emissions, consumption and power-to-weight ratios. 4-valve technology and common rail injection up to 2400 bar further increase efficiency.

Perfectly tuned drive system technology.

The engines are also used for braking: the strong premium engine brake reduces mechanical wear and tear on the brakes and makes a great contribution to economic efficiency.

The exhaust gas aftertreatment system uses BlueTec 6 technology which has already proven its worth in daily use over many millions of kilometres in our heavy-duty mass-production engines. In the exhaust gas aftertreatment unit, the SCR catalytic converter reduces the nitrogen oxides to a minimum. And the diesel particulate filter prevents almost any soot particles from escaping.

Unimog implement carrier in Euro V/Euromot IV variant.

With the U 423, U 429 and U 529 models, the Unimog implement carrier is available with modern Mercedes-Benz engines (OM 934/OM 936, 4 and 6-cylinder) in Euro V and Euromot IV versions. In these versions, no diesel particulate filter, camshaft adjustment and HC metering is used. As a result, such things as the maintenance and life cycle costs are reduced. The general model variant of the three vehicle types corresponds to the basic concept of the current implement carrier model series.

Combined with emissions level Tier4f, approval as an agricultural tractor is possible. Providing the highest economic efficiency in these applications. The Unimog fulfils the emissions standards applicable to tractors.


UGE versatility.

Stay flexible – always.

Application versatility is the trademark of the Unimog. Its reinforced portal axles with hub reduction gear guarantee high ground clearance for the most diverse of tasks – even off the beaten track.

To this end, the differential and the drive shafts connected with it are repositioned higher up. The axle tube and differential lie above the wheel centre. In this way, obstacles are easier to overcome and the vehicle’s centre of gravity remains low.

Tirecontrol Plus.

The Unimog is unchallenged.

Indispensable on off-road terrain.

The Unimog is unchallenged: setting the right tyre pressure for the task at hand is conveniently carried out at the push of a button on the display. The driver has the choice between the three pre-configured modes “Road”, “Sand”, “Rough” and “Manual”. The tyre pressure is then automatically adjusted. Thus, the Unimog can be driven with low tyre pressure on loose ground such as sand or mud and hence has a greater tyre contact area. That leads to better traction, less slipping and less damage to the land – including growing crops. Or economical and safe driving on-road thanks to a high tyre pressure and smaller tyre contact area.

The Tirecontrol Plus central tyre inflation system is available ex factory and no special conversions are necessary.
