The Lexion 520 sits in the 500 series between the 510 and the 530. It shares the 6,600.7 cm³ Caterpillar C6.6 at 2,100 rpm with its smaller brother and also has a 600.4 l fuel tank; in Europe the engine was tuned to 260 hp, against 220 hp in the 510.
More power also brings more weight and volume: the grain tank grows from 73 to 78 hl and the empty weight from 11,000 to 11,800 kg. The 520 keeps the 540 cm cutting width and the five straw walkers unchanged. The threshing cylinder is 142 cm wide.
For the US version Ritchie Specs gives 272.3 hp and a grain tank of 221.4 bushels. Both models have 625 dm² of walker area according to Koneviesti. Typical front tyres are 800/65R32.
Claas combines Lexion, Tucano, Mega and Medion – from Harsewinkel: the numbers of the Lexion 510 to 570, Montana for slopes, Terra Trac on tracks, Mercedes and Cat engines
Claas of Harsewinkel in Westphalia is Europe's largest combine maker – since the first combine-binder of 1936 and the self-propelled Hercules of 1953 – and the Lexion has been the flagship since 1995: a hybrid combine that pairs the conventional threshing drum with rotors for residual grain separation. The register shows the programme of the 2000s: the Lexion 510 to 570 with straw-walker separation (the 500 series of model years 2004 to 2010), the suffix Montana for the hillside version with levelling up to 17 percent slope, Terra Trac for the track undercarriage that Claas offered as the first maker in series from 1997, C for the version with Caterpillar engine, and the Plus for the power step. Tucano 320 to 450 is the mid-range from 2007, Mega 350 to 370 the previous generation of the 1990s, Medion 310 the entry model.

The register lists 23 versions with six-cylinders of 6,401 to 12,500 cm³ – Mercedes-Benz OM 906 LA and OM 926 LA in the Tucano and small Lexion, Caterpillar C 9 and C 13 in the big Lexion, C 6.6 in the Mega – at rated speeds of 1,900 to 2,200 rpm; the recorded output of the Lexion 570 is 180 kW.
The Lexion 500 numbers order size by walker count and drum width: 510 and 520 with five walkers and a narrow drum, 540 to 570 with six walkers and a 1.70 m drum; around 2005 the Lexion 570 was the most powerful straw-walker combine in the world.
On used combines, drum hours separate from engine hours, the condition of threshing drum, concave, walkers and sieves, wear of elevators and header, leak-free hydraulics and the cab electronics, whose repairs on older Lexions are expensive, are what count.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
