• KRONE MaxFlow and Biogas drums with different blade specifications combine for producing the
  chops length you need
• KRONE OptiMaxx roller conditioners ensure optimum fracturing and kernel treatment
• KRONE VariLOC for flexible long and short chops without conversing the machine

OptiMaize brings full flexibility to all KRONE BiG X harvesters, allowing them to produce any type of chop length livestock farmers and Biogas producers call for. MaxFlow and Biogas drums are available with various numbers of blades and combine with matching KRONE conditioners to deliver perfect 4-30 mm (0.2"-1.2") chops and the most intensive treatment. The BiG X offers this wide range of chops without operators having to swap or refit the chopping drum – simply by reducing the cutting frequency with the help of VariLOC.

• Top chop quality with six intake rollers
• High throughput with universal or biogas chopping drum
• OptiMaxx roller conditioner – Intensive conditioning
• VariStream – Continuous crop flow
• StreamControl – Optionally adjustable discharge distance
• VariQuick – Quick changeover between grass channel and corn conditioner

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.

• 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.

• 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: 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
• Straight tine rotor for high throughput

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.
