The Scania R420 LB 6X2MNB was built in 2005 and is the low chassis variant of the R series with three axles, one of which is driven. At Scania the abbreviation LB marks a chassis with a lower frame, as used for bodies with large load volume such as swap bodies. MNB denotes a further equipment feature of the configuration.
The six-cylinder engine delivers 309 kW and has 11,700 cm³ displacement. At 9,390 mm long and 2,500 mm wide the vehicle is slimmer than later long-haul tractors, which are wider, owing to its early build date. The kerb weight of 12,000 kg against a permissible gross weight of 25,700 kg allows a payload that can be well used in distribution traffic.
Compared with the base model of the R420 line, this entry is several years older and shows how dimensions and weights of the series shifted within a short time.
Scania R420 – high-output 4-series with R-cab: 12-litre inline-six rated around 309 kW, multi-axle chassis for combination haulage, gross weights up to 47,200 kg
The Scania R420 also comes from the 4-series programme launched in 1995 with the R-cab for long-haul work; the number 420 denotes engine output in horsepower under Scania's convention, rather than the engine family as in the smaller series. The R420 is powered by Scania's twelve-litre inline six, which at this output level produces around 309 kW. The axle formulas in the model names – 6X2, 6X4, 8X4 – indicate three- and four-axle chassis with varying numbers of driven axles, typical of heavy haulage and timber transport in Scandinavia.

The register lists 9 versions with around 309 kW from six-cylinder engines of 11,700 to 12,742 cc. Kerb weights range from 7,960 to 22,570 kg, gross vehicle weights from 18,600 to 47,200 kg; the latter figure corresponds to multi-axle chassis for trailer or semi-trailer combinations. Lengths run from 6,155 to 11,650 mm, widths from 2,500 to 2,600 mm.
At 309 kW, the R420 was among the more powerful variants of the 4-series and was aimed at heavy long-haul and construction transport, and, in multi-axle form, at Scandinavian combination haulage with trailers exceeding the standard 40-tonne limit. Competitors included the Volvo FH12/FH16 and the heavier versions from MAN and Mercedes-Benz.
On used examples, it is worth checking the frame and trailer coupling for cracks, particularly on multi-axle construction and timber-transport chassis with high drawbar loads. The twelve-litre engine calls for checks of the turbocharger, charge-air cooler and injection system; the brakes should be inspected especially carefully given the high gross weights. Parts are well supported through Scania's service network, and the robust 4-series platform is also routinely serviced by independent workshops.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Ask about parts availability for this build year — the running costs hang on it.
