Engine

Variable geometry turbo (VGT)

For a high torque even at low engine speeds, the turbine blades are adjusted according to the speed and load. No more "turbo lag" experienced and reduced fuel consumption.

Common rail injection system

Common rail means improved response characteristics, lower fuel consumption and a more precise adjustment of the engine to all operating statuses.

Cooled exhaust gas recirculation

The recirculation of part of the exhaust gas flow significantly reduces the pollutant emissions and increase the efficiency of the fuel burn, therefore reducing fuel consumption..

The top models, ARION 540 and ARION 640, are equipped with the innovative CLAAS POWER MANAGEMENT system. Depending on the required tractive power, PTO shaft output or hydraulic power reduction, up to 20 hp of additional engine output are released in stages under the following conditions:

The additional boost power is released by the CPM in 6 stages. It therefore never releases more fuel-hungry power than is actually required.
