Reference excerpt

The Krone BiG X is a self-propelled forage harvester manufactured by the agricultural machinery company Krone Agriculture from Spelle. Since May 2000, this vehicle has been one of Krone's main revenue generators.

History From May 2000, Maschinenfabrik Bernard Krone produced the first generation of the BiG X forage harvester as BiG X V8 and BiG X V12. Krone initially marketed the engine power as 540 hp. According to the German agriculture magazine Agrarheute, the concept of a forage harvester the size of the BiG X, capable of reaching speeds of 40 km/h and boasting high engine power, was new at the turn of the millennium, and the company was concerned that the true engine power might be perceived as oversized. In reality, the installed V8 engine, a Mercedes-Benz OM 502, had a power output of 605 hp. The BiG X V12 model was even more powerful, equipped with an OM 444 engine capable of up to 780 hp. In 2007, Krone introduced the second generation with the BiG X 800, which is powered by two different engines that can be synchronized when necessary. The second generation included the BiG X 1000, BiG X 650, and from 2008, the BiG X 500. The BiG X 700, 850, and 1100 models were added in 2010. Since 2007, Krone has equipped its forage harvesters with a photo-optical sensor as standard. Integrated into the corn header, this instrument detects the maturity of the plants through color matching, preserving the structure of the harvested crop and reducing the risk of secondary fermentation. At the 2013 Agritechnica agricultural trade fair in Hanover, Krone presented the small BiG X series, featuring the forage harvesters BiG X 480 and 580. These new models replaced the previous BiG X 500 and distinguished themselves from their predecessor primarily due to a smaller chopping unit and overall more compact dimensions. In the same year, Krone introduced the BiG X 600 Edition 2013 featuring a V8 engine from MAN. In 2015, Krone expanded its small range of forage harvesters with the BiG X 530 and 630 models. In September 2018, Krone unveiled its new large forage harvester series with the BiG X 680, 780, 880, and 1180 models, which replaced the old series. According to Krone, the BiG X 1180 is considered the most powerful forage harvester in the world. The vehicle reportedly has a harvesting capacity of 360 t/h according to agricultural technology magazine Profi. Apart from the engine, the BiG X 1180 is identical to the BiG X 680, 780, and 880 models. Also in 2018, for the first time, Krone introduced a roller conditioner called OptiMaxx with a diameter of 305 mm as optional equipment for the BiG X 1180. In September 2020, Krone unveiled a new generation of the small BiG X series, including the 480, 530, 580, and 630 models, featuring a new cabin, modified crop flow, and transition to emissions stage 5. The gap between the BiG X 880 and the BiG X 1180 in the larger series was filled in September 2022 with the introduction of the BiG X 980 and the BiG X 1080. Similar to the BiG X 1180, the largest forage harvester in the series, the two new models are equipped with V12 engines from Liebherr. Krone offers two main model ranges with the small BiG X series 480, 530, 580, and 630, as well as the large BiG X series 680, 780, 880, 980, 1080, and 1180. These ranges primarily differ in engine power and, if applicable, the diameter of the kernel processors. For the BiG X 1180, a 305 mm diameter kernel processor can be installed, unlike the other models which are shipped with a kernel processor diameter of 250 mm.

Technical description The following technical description primarily focuses on the BiG X 1180 model, which is largely identical to the BiG X 680, 780, 880, 980, and 1080 models, differing primarily in engine specifications. Reference will also be made to the smaller models in the current series where appropriate.

Worked examples

Example 1 — a first encounter with Krone BiG X

Start with the simplest possible case. Write down what Krone BiG X claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Krone BiG X 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 Krone BiG X 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 Krone BiG X

In research: Krone BiG X appears in engineering 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 Krone BiG X 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: Krone BiG X is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural machinery, Engineering vehicles, Heavy equipment, so understanding it makes those chapters shorter.
In everyday life: Look for Krone BiG X 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.
