Claas Lexion

Claas Lexion is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Claas Lexion rather than just read about it. In short: Claas Lexion is a series of combine harvesters, manufactured by Claas in Harsewinkel. An American version called Lexion is produced by Claas Omaha Inc. in the United States.

Key takeaways

Claas Lexion belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Claas Lexion to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Claas Lexion from memory before moving on to harder problems.

Reference excerpt

Claas Lexion is a series of combine harvesters, manufactured by Claas in Harsewinkel. An American version called Lexion is produced by Claas Omaha Inc. in the United States.

History The Lexion was presented in 1995. The first model was the Lexion 480. It has a harvesting capacity of 40 tonnes (39 long tons; 44 short tons) of grain per hour and was at that time the most powerful combine harvester in the world. The Lexion 480 had the same accelerator drum in front of the threshing drum as the Claas Mega, but it came with a bigger threshing drum (600 mm [24 in] diameter and 1,700 mm [67 in] width instead of 450 mm [18 in] diameter and 1,580 mm [62 in] width). Instead of the straw walkers, the Lexion 480 had two separation rotors installed. As a result, the unit ran smoothly and the throughput was much higher than in a conventional straw-walker machine. From 1999, Claas worked with the US agricultural and construction machinery manufacturer Caterpillar and sold the Lexion combines in North America under the CAT brand. In 2002, Claas took over 50% of the joint venture with Caterpillar and the combine harvester production in the United States. The harvesters produced there were then still marketed as CAT Lexion. At the 2005 Agritechnica exhibition, Claas presented the Lexion 600, with a cutting width of up to 12 m (39.37 feet), a grain tank capacity of 12,000 liters (330 Bushels) and a performance up to 60,000 kilograms per hour (130,000 lb/h). This was again the most powerful combine harvester in the world. In 2010, Claas presented the Lexion 700. In 2013, Claas introduced new emission standards (Tier 4). The Lexion 8900 released in 2019 has a 581-kilowatt (779 hp) MAN D42 engine that matches the Fendt Ideal 10,000-kilogram (22,000 lb) class 10 combine released in 2020.

Lexion series 400 series (two separation rotors) 500 series (six straw walkers) 600 series (six straw walkers) 700 series (two separation rotors) 5000 series (five straw walkers) 6000 series (six straw walkers) 7000 series (two separation rotors) 8000 series (two separation rotors)

Worked examples

Example 1 — a first encounter with Claas Lexion

Start with the simplest possible case. Write down what Claas Lexion claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Claas Lexion before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Claas Lexion ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Claas Lexion

In research: Claas Lexion appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Claas Lexion in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Claas Lexion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Claas, Combine harvesters, so understanding it makes those chapters shorter.
In everyday life: Look for Claas Lexion outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
