Engine power
185 hp
As published: 185 hp rated, plus 20 hp CPM boost (205 hp total)
The CLAAS ARION 660 is a row-crop tractor in the 185 hp class, with a 6.8-litre six-cylinder engine. It is built for mixed farm work, from cultivation and haulage to loader and front-linkage implement work.
CLAAS rates the tractor at 185 hp, with a 20 hp boost from CLAAS Power Management (CPM) during PTO and transport work, for 205 hp in total. The rear PTO runs at 540, 540 ECO, 1,000 and 1,000 ECO rpm, and the front PTO is 1,000 rpm.
Independent PTO tests give lower usable power than the rated figure, so compare PTO output on the same test basis. Check the transmission (CMATIC on the 660) and the equipment package with a dealer before comparing.
