Charting 20 years of development for Krone's Big X forage harvesters

Turning 20 years old is a major milestone for any machine production run, not least in the fast-paced world of forage harvesters. However, for Krone’s Big X range, the original concept has stood the test of time. With the help of Krone UK’s James Duggleby, Alex Heath charts the major developments of the machine.

Rolling out of the assembly hall at Spelle, Northern Germany on May 20, 2000, the first Big X signalled the final step in Krone’s transition from a general agricultural machinery manufacturer to a specialist in forage technology.

 

Reacting to the decline in popularity of forage wagons and trailed foragers, the design brief was simple; the company would offer something bigger than the other manufacturers at the time. An engine capable of 600hp was a must, while maize headers with eight, 10 and 12 row options were also needed, as six rows were most prevalent. In addition, a host of electronic features, many of which would later be adopted by the wider market, would deliver performance and operator comfort.
