The chopper unit

Optimum layer thickness

It's not just the number of blades that accounts for a good quality chop. The thickness of the mat that passes through them and therefore the width of the chopping drums are just as important. Therefore KRONE designed a wider 630 mm chopping drum for the BiG X 480, 530, 580 and 630 which carries the customary high chopping quality of the high-capacity foragers with 800 mm drums over to the smaller models.

When you’re looking to maximize throughputs with a top-quality chop, the technology must be up to the job. With the BiG X, ­KRONE offers a forage harvester which convinces by top cutting quality, highest throughput and maximum user comfort thanks to the direct crop flow and the numerous innovative details which meet the requirements of successful service providers and make the working day easier.

The intake system
  • 6 pre-compression rollers for top-quality chops
  • Hydraulic drive
  • Stepless adjustment of the chop length from the cab
  • Automatic adjustment of the chop length via AutoScan or NIR sensor
  • Maximum protection against foreign objects
  • Long path from metal detector to chopping drum
  • Metal detection across the entire channel width

On a BiG X, it is also the intake system that has an influence on the quality of chop. The six intake rollers compress the chopping crops consistently at a high pressure so that it is easier and more precisely to chop. The hydraulic drive of the intake system allows operators to choose between setting the cutting length manually or automatically.

The chopper unit
  • Chopping drums with 20, 28, 36 or 40-blades for OptiMaize S to XL
  • High flywheel mass: Closed drums with a diameter of 660 mm
  • Top chop quality: Drums with a width of 630 mm matched to BiG X 480, 530, 580 and 630
  • Low fuel consumption: High flywheel mass, pulling cut

Matching the drum dimensions to the harvester model and choosing the optimum number and shape of blades not only boosts the power of the BiG X but also makes the OptiMaize S, M, L, and XL more flexible to suit more applications. The wide range of drums available for BiG X deliver a top-quality chop in any conditions anywhere in the world – at top performance levels.

The KRONE MaxFlow chopping drums
  • For grass, wilted crops, whole crop silage and maize in OptiMaize S, M, L, XL
  • Chopping drums with 20, 28, or 36 blades
  • Plenty of carrying space under the blade carriers
  • Blades are quick and easy to insert and remove

The MaxFlow chopping drums are specially designed for conditioning of high-quality silage. Harvesting wilted crops with unevenly formed swaths is a challenge for the chopping drum; therefore, its blade supports have a special shape which leaves more room under the blades. Larger ‘pockets’ and the spring-loaded drum base result in extremely smooth running and high power reserves. So BiG X makes light work of temporary crop accumulations.

The KRONE biogas drum
  • 40 blades arranged in V-shape
  • High frequency of cuts
  • High productivity
  • OptiMaize S
  • High gas yields

With its 40 blades, the KRONE biogas drum chops the crops very thoroughly. OptiMaize S achieves very short chop lengths which enable high throughputs both on the machine and in the fermenter, making BiG X a major factor in biogas plant productivity.

  • OptiMaize is a versatile and unique system
  • Cutting length gearbox for flexible use in short and long cut applications
  • Changeover of the drum speed is a matter of a few minutes
  • No machine conversion, no up-front planning

VariLOC is a gearbox in the pulley of the chopping drum. By simply changing the drum speed from 1,250 to 800 rpm using a standard open-end wrench, you can increase the chopping drum’s LOC range by up to 50 %. This makes a quick changeover between long or short chops possible. You can fulfil your customers' fluctuating demands without any conversion or up-front planning. Combined with the new 105/123 tooth roller conditioner (with 30 %, 40 % or 50 % speed difference), this gearbox turns your BiG X into an all-rounder and gives you maximum flexibility.

The KRONE OptiMAXX roller conditioners

Our roller conditioners redesigned

  • 570 mm wide and 250 mm diameter OptiMaxx roller conditioners

  • BusaCLAD-Special coating technology for maximum service life
  • The gap between the rollers is conveniently adjusted from the cab
  • A strong spring assembly provides a consistent and high pressure
  • Maximum fracturing from an up to 50% speed difference (option)

Every single kernel must be cracked to achieve an optimal digestibility. These user demands are perfectly met by the new OptiMaxx roller conditioners with their slanted teeth, a new KRONE development. The rollers score on a massive 250 mm diameter and a 570 mm width

KRONE VariQuick
  • Fast changeovers from grass channel to corn conditioning and vice versa
  • A chain drive lowers the unit conveniently
  • The changeover takes just a few minutes
  • Fast and easy removal of the grain conditioner

VariQuick is the system that allows operators to converse BiG X very quickly from maize to grass and the other way round. A chain drive (electric option) moves the corn conditioner out of or into the crop flow. If the corn conditioner is not used for longer periods of time, you can lower it and remove it from the machine by pulling it out to the side.

KRONE VariStream
  • Consistently smooth performance despite inconsistent crop flows
  • Extremely quiet running even in uneven swaths
  • High throughputs
  • Top quality chop
  • Perfect operator comfort

VariStream comprises spring-loaded floors beneath the chopping drum and behind the discharge accelerator rotor. The system ensures blockage-free and smooth operation, even in varying volumes of crop. The technology allows operators to utilise the forager to its limit and use less fuel per hour.

KRONE StreamControl
  • Adjustable discharge distance from the cab as an option
  • Tight crop stream even with a long crop discharge
  • The shorter the crop discharge, the less power is needed
  • Fills the transport wagon accurately without spillage

The crop throw is controlled from the cab by adjusting the flap in the rear wall on the discharge accelerator.This way, operators can adjust the throw quickly to the current filling situation. As the accelerator needs less power to cover a short distance, the operator can free up engine output and use it for chopping and higher throughputs.

The KRONE headers
  • Convenient attachment and removal
  • Maximum safety
  • Very short set-up times
  • Compact combination

The multi-coupler system of the BiG X allows operators to couple headers fast, easy and dependably from the seat, reducing changeover times when preparing for road travel or different crops.This way, more time is spent on productive work.
