Claas Axion: high-power tractors, engines and what to check
Claas Axion — high-power versatile tractors, produced since 2005. We look at the Axion 800 and 900 series, engines, transmissions and what to check when buying a used Axion.
Axion in brief
Claas Axion — high-power tractors from the German manufacturer, designed for large farms, fieldwork, sowing and transport. Nominal power ranges from around 200 to over 400 HP.
The Axion is praised for its comfortable cabin, good visibility and seamless CMATIC transmission. In the used market, it often undercuts similar John Deere or Fendt models.
Series and versions
The Axion 800 is the lower-power series, while the Axion 900 is the higher-power series, designed for heavy-duty work. Some models feature the Terra Trac version — with rubber tracks at the rear.
Over time, the series has been updated, so engine standards and cabin design vary. Before purchasing, it's essential to determine the exact model year and production date.
Engines and transmissions
Axion engines are six-cylinder diesels (Perkins or FPT), meeting various Stage standards. Newer models use an SCR system with AdBlue.
Transmissions include semi-automatic (Hexashift or Eccom) and seamless CMATIC. The choice depends on the series and trim level.
What to check when buying a used Axion
Check the engine hours, oil and coolant leaks, turbocharger, SCR/AdBlue system and hydraulic operation. Ask for the service history.
Check the operation of the gearbox, clutch, play in the front and rear axles, lifting mechanism, and cabin electronics. In the Terra Trac version, inspect the wear of the belts and pulleys.

Names and equipment vary by market and year of production; we list the versions most commonly found in Europe.
