Claas has released details of its new four- and six-cylinder Arion tractor line-up to meet the Stage IIIB exhaust emissions standard. There are three Arion 500 four-cylinder models (530, 145hp max; 540, 155hp; and 550, 163hp) and four new Arion 600 six-cylinder models (620, 158hp; 630, 165hp; 640, 177hp; and 650, 184hp) that will all use Deere Power Systems engines and won’t need AdBlue.
First launched at the Agritechnica 2007, the Arion 500 and 600 tractor ranges have proven to be a major seller for Claas on account of their versatile power-to-weight ratio, comfort and economy. More than 10,000 Arion tractors have been sold around the world, and in the UK, where the Arion range straddles the current average horsepower, the Arion 640 has consistently been the top-selling Claas tractor.
Under the bonnet of the new Arion range, which will be available this autumn, Claas has stayed loyal to Deere Power Systems (DPS) for engine supply. These power units features the latest engine technology in order to comply with the Stage IIIB emissions regulations while also offering enhanced performance.
Power for the new Arion range comes from the latest DPS Powertech PVX engines, that use a diesel oxidation catalyst and diesel particulate filter in order to meet the new standards. As part of the Claas Power Systems philosophy of using the optimum technology and components, this engine has been chosen both for its performance and compatibility with the tractor’s transmission and other components.
The engines also feature four-valve technology, a variable-geometry turbocharger, intercooling and a new common-rail injection system that operates at 2,000 bar rather than the 1,320-bar system used previously.
The level of braking can be adjusted on the IntelliView III touch screen to accommodate sensitive surfaces such as grassland. The same adjustment can be applied to the independent brake pedals, not allowing them to lock the wheels. For safety the independent brakes are automatically electronically locked for road speeds.
The hill holder function on Power Command models improves tractor control on slopes, automatically engaging the brakes to prevent the machine rolling back during hill starts and easing clutch engagement. On Auto Command tractors this safety feature is provided by the active stop incorporated within the CVT logic.
