Powerful and soft
Despite pumping out an enormous power of up to 423 hp, this new and advanced CommonRail, inline, six-cylinder MAN engine runs even quieter than its predecessor model. Equipped with SCR Selective Catalyst Reduction technology to inject liquid urea into the exhaust fumes, the unit complies with Emission Stage IIIB / Tier 4i regulations. The advantage is obvious – there is no need for exhaust gas recirculation, so that the engine can generate its full power at greater efficiency.

Merging more than 9 metres (29'6") of crop into one swath
This optional merging system groups all passes into one – cutting, conditioning and windrowing. Integral augers in the two side mowers feed the conditioned material directly to the swath left by the front mower. This optional system offers extraordinary benefits in harvest chains that do without tedding and swathing. The system produces excellently clean swaths in grass, alfalfa and wet silage, which are easily picked up by the following harvester.
