Triple test: Claas Arion 530 Cebis, 620 CIS and 620 C This month’s profi Powermix test results are proof of how much effort has been made by engine manufacturers in their quest to improve fuel consumption. The ‘newer’ four-valve units within the Arion 530 Cebis and 620 CIS guzzle markedly less juice.
To summarise the preceding tractor test pages, all three of the featured Claas models are powered by DPS engines. Least sophisticated of the three motors is the unit within the 620 C which, along with its 610 C and 630 C sibs, is marketed by Claas as a lower cost, easy-to-operate entry-level tractor. Engine in the 620 C’s
case is a six-cyl 6068 HRT 85B with almost 6.8 litres of capacity, common-rail fuel injection and two valves per cylinder. In addition, there’s a fixed-geometry turbocharger, and the motor also uses internal
exhaust gas recirculation technology.
The other two tractors, the 530 Cebis and 620 CIS, are powered by more advanced engines. While still utilising common-rail injection and intercooling technology, these units take a step up in terms of their spec sophistication by incorporating four valves per cylinder, a variable-geometry turbo and external exhaust gas recirculation. The smaller of the two tractors, the 530 Cebis, uses a four-cylinder 4.5-litre 4045 HRT 80C engine, whereas the physically larger 620 CIS model plays host to a six-cylinder 6.8-litre 6068 HRT 83C.
Capacity of the 620 CIS is identical to that of the 620 C.
