For this vehicle the register lists an engine of 7,200 cm³ displacement and 240 kW output. Overall length is 11,260 mm, width 2,550 mm.
An engine of this size goes well beyond what would be needed simply to propel a vehicle of this length, pointing to a vehicle with driven working equipment, such as a pump, a milling unit or a similar permanently fitted installation. On special vehicles like this, it is usually the working equipment rather than road propulsion that dictates the choice of engine and drivetrain. The generous width of 2,550 mm makes almost full use of the allowance many European countries grant special vehicles above the usual 2.55-metre limit for ordinary commercial vehicles.
For a used example of this type, check in particular the operating hours and maintenance state of the working unit, the condition of the hydraulic system including hoses and pumps, and the frame and running gear for corrosion and wear under heavy load. The clutch and gearbox of the large-displacement engine should also be checked before buying, along with the seals and fittings around the working equipment for leaks.
