The Claas Ares 836 and the Claas Arion 660 are both tractors — here is how they stack up on the figures that matter. Both are rated at the same 205 hp. Claas Ares 836 is the lighter machine (6,751 kg vs 7,859 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work.
