The new Big-X680, 780 and 880 models become part of a range of 12 models with power outputs from 490 to 1100hp.
A complete re-design sets the three new models apart from the rest of the range, and offers a world-first cab lift system that will be debuted on a Big-X machine at Agritechnica ‘17. It will allow operators to raise the cab at the touch of a button by up to 70cm, using an under-cab hydraulic scissor lift layout; this should allow better vision over the crop and into trucks and trailers travelling alongside.
An additional bonus is the lowering of cab noise because the base of the unit is located away from the chopping cylinder.
A key part of the re-design is the addition of the company’s multi-tank concept: up to five storage tanks, in seven configurations, hold additives or inoculants in large quantities that allow longer intervals between refills, and so more productive days.
Available with Krone’s OptMaize Universal package, the new Big-X models can offer chop lengths of 3 - 30mm using the MaxFlow cylinder and Virilocal feed roller gearbox. Ease of adjustment such as reducing the cylinder speed from 1250 to 800rpm allows the operator to double the chop length without the need to remove any knives.
Standard gear includes the VariStream crop flow system for the cylinder, and the blower housing with spring-loaded lower concaves which adjust to give blockage-free crop flow in all conditions. The new models will have Liebherr Tier 4 engines, which in the case of the Big-X 880 (16L, V8) push out 900hp.
The new machines are said to offer excellent manoeuvrability through independent wheel suspension, good especially on undulating paddocks.
And new geometry allows the fitment of tyre equipment up to 900/60 R42 which helps increase ground clearance, reduce compaction and improve operator comfort.
