6R1500 by Rolls-Royce for Claas Xerion

Claas has really thought big with the Xerion 12 Series, associated with the 6R1500 series from Rolls-Royce Power Systems. The Claas open field tractors, which face Fendt’s German countrymen, are the Xerion 12.590 and 12.650, featuring engines with power outputs of 366 and 480 kW.

For the top Xerion Claas thought of the Rolls-Royce 15.6L-diesel engines

Providing the required power is the mtu 6R1500, 6-inline 15.6 liter Diesel engine (BxS 139/171 mm), which this year celebrates the tenth anniversary of its designation as Diesel of the year. It was in fact the year 2013 and at bauma Munich Michale Haldinger, at the time sales manager of Tognum. mtu changed its name in January 2014, as an onomastic seal of approval from Rolls-Royce. A mechanical project, that of the mtu engine families, which would accompany the brand up to Stage V, pivoted on the balance between injection pressures and stress control.

Let’s go back to the X12 Series

We are talking about two tractors that sit directly in the German brand’s highest power class, above the Xerion 4200 and 5000. Featuring a low-speed transmission and an enormous hydraulic pump capacity of up to 537 l/min, they bring a cutting-edge technology package, the crème de la crème of Harsewinkel’s R&D department, starting with the Cemos operator assistance system. Vehicles that can also be fitted with Terra Trac technology, with the latest generation of cushioned tracks (the very ones we saw at work in the demonstration), capable of improving traction, operability and comfort on board.

But let’s go in order, because there is a lot on the plate.

Designed as highly efficient specialists for the heaviest towing jobs, such as towing large cultivators and seed drills, as well as harvesting boxes, the 12.590 and 12.650 models are designed for the North American, Central and Western European, South American and Australian markets.

Talking about Xerion powertrain

The low-speed 2.0 concept represents a perfect synthesis of the efficient Rolls-Royce Power Systems engine or, if you prefer, the OM473, in the Mercedes-Benz nomenclature (even after the divestiture, this family is produced by changing its name and architecture (e.g. supercharging and fuel injection) depending on its intended use), and the optimally coordinated continuously variable transmission, all crowned by the engine’s high-performance, low-speed hydraulics with the highest hydraulic output on the market. With a maximum power output of 480 kW (653 hp) and a maximum torque of 3,100 Nm, the 12 Series Xerion is currently the most powerful all-wheel-drive tractor with continuously variable transmission on the market and features the well-known Cemos operator assistance and process optimisation system of Claas standard tractors with Cmatic continuously variable transmission.
