The engines will comply with the EU’s Stage V emissions standard, due to come into force in 2019.
Claas will be fitting the new MTU Series 1000 to 1500 engines to its Lexion and Tucano combine-harvesters, its Jaguar forage harvesters, and its 4×4 high-horsepower Xerion tractors.
These engines, based on Daimler commercial vehicle engines, cover a broad power range from 134hp to 643hp.
“With an eye on, among other things, the EU Stage V rmissions directive, we’ve decided in favour of these tried-and-trusted engines from MTU to power a large proportion of our vehicles,” said Bernd Kleffmann, Head of Systems Engineering Development at Claas.
“We already have more than 10 field-trial vehicles fitted with EU Stage V MTU engines and are very satisfied with them.”
The vice president of industrial business at MTU, Bernd Krüper, said: “We’re delighted at winning one of the most renowned agricultural machinery manufacturers for the EU Stage V engines we’ve introduced.
“This is a continuation of our long-standing success story with Claas.”
As well as reducing the mass of particulates in exhaust gases, the EU Stage V regulations due to come into force in 2019 are also intended to put a limit on the number of particles.
The engines meet these tighter emissions limits by having an additional diesel particulate filter, and thanks to internal design improvements intended to reduce fuel consumption.
Rolls-Royce’s MTU brand is world-renowned in high-speed diesel engines powering applications as diverse as rail locomotives and luxury yachts.
