• 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.

• Chopping drums with 20, 28, 36 or 40-blades for OptiMaize S to XL

• Top chop quality: Bespoke 630 mm wide drums for the BiG X 480, 530, 580 and 630 models
• 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.

• For grass, wilted crops, whole crop silage and maize in OptiMaize S, M, L, XL
• Chopping drums with 20, 28, or 36 blades
• Large conveyor space under the blade carriers
• Quick blade insertion and removal

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.

• 40 blades arranged in V-shape
• High cutting frequency
• High efficiency
• OptiMaize S
• High gas yield

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.

• All-rounder with OptiMaize thanks to globally unique system
• Cutting length gearbox for flexible use in short and long cut applications
• Drum speed changeover in just a few minutes
• No additional conversion or planning required

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.

• 570 mm wide OptiMaxx roller conditioner with a diameter of 250 mm
• Helical toothed profile for perfect conditioning for OptiMaize S to XL
• BusaCLAD - Coating technology for maximum service life as an option
• The gap between the rollers can be conveniently adjusted from the cabin
• Strong spring assembly for consistently high contact pressure
• Intensive fracturing with optionally up to 50% speed difference

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.

• Quick changeover from grass channel to corn conditioning and vice versa
• Convenient changeover via a chain drive
• The changeover takes just a few minutes
• Fast and easy removal of the corn 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.

• Consistently smooth performance despite inconsistent crop flows
• Extremely quiet running even in uneven swaths
• High throughput
• Best 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.

• Adjustable discharge distance from the cabin as an option
• Concentrated crop stream even if discharge distance is long
• Lower power requirement as discharge distance decreases
• Loss-free, precise filling of transport wagons

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.

• Convenient attachment and removal
• Maximum safety
• Minimum set-up times
• Compact attachment

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.

• More power, quiet running, less wear
• Stepless speed adjustment from the driver's seat
• Automatic speed adjustment to the driving speed
• Quick coupler with round bracket for easy attachment and removal and optimum contouring

The camless EasyFlow 300 S and 380 S pick-ups by ­KRONE have neither deflection rolls nor cam tracks. Compared with conventional pick-ups, EasyFlow has up to 58% fewer moving parts, which makes it impressively smooth running, low-wear and therefore inexpensive in service and maintenance. EasyFlow operates 30% faster for cleaner gathering and increased productivity.

• Direct cut headers with working width of 6.20 m or 7.10 m
• High throughput low power requirement
• KRONE EasyCut mower technology – Proven the world over
• KRONE SafeCut – Unique protection for cutting discs
• Powerful feed auger with replaceable Hardox wear plates

Based on the proven ­KRONE EasyCut mower technology, the BiG X with the XDisc direct cut headers can mow and chop whole crop silage in one operation. SmartCut ensures high cutting performance with the best cutting quality, while SafeCut prevents damage from foreign objects.

Quick-change blades are a must for many farmers and contractors, because this way they can replace blades quickly and easily on the site.

With some cutting discs turning in pairs towards each other and others turning away from each other, it was necessary to redesign the degree of blade overlap to ensure cleanest swaths. For a stripeless swath, we have therefore increased blade overlaps on the cutter blades turning outwards between the discs turning away from each other. In addition, the blades turning to the rear are set further apart to encourage a smooth flow of large volumes of crop.

If the system is suddenly overloaded, the impact is not directed to the spur wheels in the cutterbar, instead the roll pins in the sprocket drive shaft shear off. The pinion shaft, which continues rotating, turns the cutting disc upwards via a lifting thread. moving it out of the risk zone and the orbit of the neighbouring discs. As a result, SafeCut prevents damage to the spur wheels and the neighbouring discs. The roll pins are replaced within a few minutes, saving costs and minimizing downtime.

You know it too well – foreign objects can cause great damage and costly repairs. ­KRONE SafeCut offers a maximum of protection and peace of mind. A unique technology protects the cutting discs from foreign objects. The XDisc comes with SafeCut as standard.

KRONE XDisc is the versatile specialist mower for whole crop silage that cuts the crop cleanly and without wastage. The huge 900 mm diameter auger makes the unit enormously powerful and has no trouble picking up very long and bulky material.

With its working width of 6.20 metres, the ­KRONE XDisc 620 direct cut header achieves a high acreage output and therefore efficient harvesting of whole crop silage.

• 7.10 m working width for even higher throughput
• Clean cut thanks to EasyCut mower technology
• Optional: Side cutting blades can be conveniently swivelled out of the cabin
• Optional: Crop press roller unit for an even crop flow
• Optional: Integrated transport chassis for minimal setup times

The ­KRONE XDisc 710, a direct cut header with a working width of over 7 m and optional integrated transport chassis, sets new standards in terms of throughput and comfort. The 900 mm diameter feed auger can be adjusted three times in the base height, enabling optimum throughput. Optional side cutting blades are available which can be conveniently swivelled out of the cabin.

The XDisc 710 can be optionally equipped with side cutting blades which can be easily and conveniently swivelled up and down independently of each other hydraulically from the cabin of the forage harvester. This innovative and unique function offers an enormous advantage: efficient utilisation of the maximum working width prevents harvest losses from laterally protruding ears or climbing plant parts at the edge of the crop; this would occur if the cutting blade was not actively swivelled upwards.

To ensure a continuous crop flow even in dense and tall crops, the XDisc 710 can be optionally equipped with a crop press roller unit. This ensures an even crop flow to prevent blockages and enables smooth operation even under extreme conditions.

As there is no need to find a parking space for the transport wagon, there is also no need for awkward manoeuvring before harvesting begins. The XDisc 710 is easy to handle thanks to a swivelling single axle on the right next to the header adaptation and a folding drawbar with support jack on the left front side. By hydraulically swivelling the drawbar and axle, both chassis parts disappear behind the header during field work, leaving the working area clear

For transport on public roads, the chassis is swivelled under and the drawbar hydraulically next to the direct cut header. After the folding process, the direct cut header is attached to the tow coupling of the forage harvester. The integrated transport chassis replaces the additional transport wagon which was previously required, thereby making field changes considerably easier. Thanks to its innovative design, the direct cut header can be transported on the road safely and in compliance with the law as a stand-alone unit with an integrated lighting unit.

The drive chain for the auger conveyor is actively lubricated – this helps to minimise maintenance work on the direct cut header and to increase the service life of the drive chain

For a consistently clean cut in all conditions, the bearing pressure can be infinitely adjusted from the cabin of the forage harvester. The cutting height can be adjusted very easily and without tools using the centrally adjustable ground skids. If it is necessary to adjust the cutting angle, this is possible via a 3-way adjustable hole pattern on the round arch holding fixture.

The KRONE XDisc 710 impresses not only with its performance, but also with its outstanding accessibility and ease of maintenance. To change the blades, the guard cloth is folded up and the blades are replaced using the quick release fastener. The blades can be removed quickly and easily using the standard spare blade drawer. In addition, the centre hood can be easily swivelled upwards to allow free access to the intake rollers.

The large 900 mm diameter feed auger is designed for high throughputs. Its speed can be adjusted in three stages to the intake speed of the forage harvester, depending on the cutting length of the mown crop. In addition, the base height of the auger conveyor can be manually adjusted in three stages using eccentrics to allow the crops to pass through in the appropriate way. In addition, the free-moving auger conveyor can simply deflect upwards in the case of bulky crops.

The powerful XDisc 710 is characterised by its exceptional robustness, enormous efficiency and high throughput. Two rigidly connected cutterbars are driven in a force-fit manner via universal shafts and angular gearboxes, starting from a central input gearbox. This guarantees an even cut even at maximum throughput, essential for outstanding chop quality. The drive train is specially designed for high input power and does not require an overload clutch. The auger conveyor is protected by a star ratchet clutch integrated into the gearbox and is driven by an actively lubricated chain drive, thereby ensuring a long service life

With its impressive working width of 7.10 m, the KRONE XDisc 710 direct cut header sets new standards in terms of performance. Thanks to its precise cut and perfect crop flow, it offers an extremely efficient solution for harvesting energy crops. With its integrated transport chassis, it also makes it quick and easy to move between locations, further increasing efficiency
