Revamped Claas tractors easier to operate

Seven models of the 4-cylinder DPS engines in the Arion 500 series deliver outputs of 125 to 165hp, and the 6-cylinder DPS in the Arion 600 series deliver 145 to 205hp.

While power outputs remain unchanged, the new engines have a 6% to 14% improvement in the torque curve at lower revs, and a reduced engine idling speed to 650rpm in the Arion 600 models saves fuel. 

All engines meet the Stage V emissions standard using a combination of cooled exhaust gas recirculation (EGR), a diesel particulate filter (DPF) and selective catalytic reduction (SCR) catalytic converter. The 600 series now shares the same, smaller SCR catalyst mounted on the front right hand ‘A’ pillar as the 500 series, helping to improve visibility. 

The Arion 600/500 tractors can be configured with a choice of the basic Claas Information System (CIS), the intermediate Claas Information System Plus (CIS+) or the advanced Claas Electronic On-Board Information System (CEBIS).

CIS uses mechanical spool valves, while the CIS+ has electronic spool valves. Both systems have the CIS terminal and a multi-function armrest with a four-way control lever.

The CIS+ is aimed at customers who want greater convenience and efficiency but do not need all the functionality of the CEBIS system. It also provides the option of using the CMATIC continuously variable transmission without the CEBIS system.

Operators of CEBIS specification tractors will benefit from several new features including the CEBIS touchscreen terminal that has a new ISOBUS UT interface that enables all tractor and implement functions to be managed using one terminal in most situations. Additionally, the ability to link up to two cameras to the CEBIS screen avoids the need for an additional screen in the cab. 

ISOBUS sockets can be fitted to the front and rear of the tractor, and CEBIS spec tractors can link an engine speed memo button to an external PTO button. 

With four-point cabin suspension and optional front axle suspension, Arion tractors are respected for driver comfort, so the addition of a new ‘dual motion’ driving seat, tinted rear windscreen, roof hatch and hands-free phone takes driver comfort to another level. 

Additional improvements include a compressed air connection, new LED work lights and redesigned battery poles, making it easier to connect jump leads or power leads for fuel pumps.
