MERCEDES-BENZ Trucks has responded to customer feedback by introducing more powerful versions of its 4x4 Unimog UGE implement carrier. 

Now available for order by UK operators, the U435 and U535 produce 260 kW (354 hp), representing an increase of 40 kW (54 hp) on the highest output previously available from the Euro VI Step E 7.7-litre in-line six-cylinder engine. Maximum torque is up by 180 Nm to 1,380 Nm, which is available from 1,800 rpm.

Daimler Truck engineers have also purpose-designed and built an automated manual transmission to manage the higher outputs of the U435/U535. The Opti-drive system’s improved gear change co-ordination and clutch control produces quicker shifts that translate into a smoother ride and improved fuel efficiency. As a result, it is expected to prove popular with UK operators as an alternative to the standard-fit manual gearbox.

In other developments, the Unimog implement carrier can now be specified for the first time with self-levelling suspension for the rear axle. This new set-up, which employs gas storage tanks and hydraulic cylinders, instead of the usual coil springs, offers benefits in terms of comfort and operational efficiency. 

As well as providing a constant driving level irrespective of load status or any rear attachments that may be fitted, the hydropneumatic system contributes to handling stability and assists operators when coupling and uncoupling implements.

Head of special trucks Ross Paterson said: “Many of the innovations and developments we’ve introduced have been in direct response to feedback from those, here in the UK, who buy and operate our vehicles. We listen to what they tell us, and wherever possible we deliver what they need.

“That’s certainly been the case where the U435 and U535 are concerned. Farmers and arboriculturalists in particular wanted that little bit more power and torque at the wheels for in-field operations, as well as for trailer work.

“We’ve taken that feedback on board and delivered what they asked for – a Unimog with comparable outputs to some of the bigger agricultural tractors, but which leaves those same tractors standing when it comes to on-road performance.”
