The Claas Arion 660 and the Claas Axion 840 are both tractors — here is how they stack up on the figures that matter. Claas Axion 840 leads on rated power with 213 hp against 205 hp. Claas Axion 840 is the lighter machine (7,416 kg vs 7,859 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Claas Axion 840 holds more fuel (406.9 L vs 367 L) for longer stints between fills. Claas Arion 660 is the newer design (2024 vs 2006). In short: choose the Claas Axion 840 for outright pulling power, or the Claas Arion 660 if a tighter budget and lighter footprint matter more.
