Mit der Umstellung auf die Abgasstufe IIIB (Tier 4 i) bekommt der Claas Arion nicht nur einen Rußfilter. Auch die Kabine ist ganz neu und mit dem Arion 650 gibt es ein neues TopModell mit 129 kW/175 PS (Maximalleistung nach ECE R 24).
The Claas Arion 640 is an all-wheel tractor with 129 kW (175 HP). The 6-cylinder engine by John Deere has a capacity of 6,788 cm3 as well as electric common rail injection and 4-valve technology. The driver has a choice of 24 forward and 24 reverse gears, and there are two further gears available which can be used for vegetable harvesting, for example. The built-in HEXASHIFT transmission with HEXACTIV automatic shifting make the Claas Arion 640 a user-friendly and efficient tractor. The Claas Arion 640 weighs approx. 6,820 kg, and has a permitted maximum weight of 11 t, which means that it can carry a payload of 4,180 kg. The working hydraulics produce 110 l/min and operate up to a maximum pressure of 200 bar. The Claas Arion 640 also stands out because it is comfortable and easy to use: the driver's cabin has air conditioning and a cooling compartment, an adjustable steering column, an air suspension seat and an adjustable, multifunction arm rest. All of the Claas models from 650 to 550 have either the CIS cabin fitting or the CEBIS variant. The first option is particularly suited to situations which require frequent changes, for example in multi-crop farms. The CEBIS cabin fitting, on the other hand, has a lot of automatic functions and it has the CMOTION multifunction control lever. All of the operating controls are fitted into the arm rest, which makes this version ideal for prolonged use.
