BiG X 680 – 1180, these are the extra powerful forage harvesters from ­­KRONE with an output of 687 to 1,156 HP. They impress not only with their high output and chop quality, but also with their comfort and handling.

KRONE OptiMaize

• KRONE chopping technology for optimum maize forage quality
• OptiMaize S, M, L, XL for variable chopping lengths from 4 mm to 30 mm
• 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.

The crop flow

• Six intake rollers ensure a top-notch quality of chops
• High throughput with universal and biogas drums
• OptiMaxx roller conditioners for intensive kernel processing
• Flexible chop lengths through VariLOC and the use of only half the number of blades
• Continuous crop flow from VariStream
• Variable crop throw is an option using StreamControl
• Quick changeovers between corn and grass thanks to VariQuick

Its innovative technology makes the BiG X a superior chopper with respect to performance and quality. Chopping lenghts can be set to individual requirements by adjusting the speeds of the intake rollers and using different numbers of blades on the chopping drum. Highest through puts are implemented by the spring-loaded floor underneath the drum and a spring-loaded accelerator backplate which guarantee a continuous crop flow.

The intake system

• Hydraulic drive: The chop length is steplessly adjustable from the cab
• Automatic setting of the chop length via AutoScan or NIR sensor
• 6 pre-compression rollers for top-quality chops
• Perfect protection from foreign objects: Long path from the metal detector to the chopping drum and metal detection across the entire width of the channel

On a BiG X, it is also the intake system that has an influence on the quality of chop. The six intake rollers continuously press the chopped material with high pressure so that it can be chopped more easily and precisely. The hydraulic drive of the infeed elements allows manual or automatic adjustment of the cutting length.

The KRONE chopping assembly

• KRONE chopping drums with 20, 28, 36, 40 or 48 blades
• High flywheel mass Closed drums with a diameter of 660 mm
• Top chop quality Drums with a width of 800 mm matched to BiG X 680 – 1180
• Low fuel consumption High flywheel mass, pulling cut

Matching the drum dimensions to the forager model and choosing the optimum number of blades not only boosts machine power but also makes the forager more flexible to suit more applications. The wide range of OptiMaize drums that are available for BiG X deliver top-quality chops in versatile applications anywhere in the world.

The KRONE Biogas chopping drum

• 40- and 48-blade Biogas drums for OptiMaize S results
• High cutting frequency, fewer overlengths
• Very economical: high throughput at low consumption
• Short chops for high gas yields

The KRONE Biogas drum with 40 or 48 blades chop the material very intensively. OptiMaize S achieves very short chops which enable high throughputs both on the machine and in the fermenter, making BiG X a major factor in biogas plant productivity.

The KRONE OptiMAXX roller conditioners

• OptiMaxx roller conditioners with 250 or 305 mm diameters
• Slanted teeth for perfect conditioning to combine with OptiMaize S-XL drums
• 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)
• BusaCLAD-Special coating technology for maximum service life

Every single kernel must be cracked to achieve an optimal digestibility. These user demands are perfectly met by the new OptiMaxx 250/305 roller conditioners with their slanted teeth, a new KRONE development.

VariLOC

• OptiMaize is a versatile and unique system
• Gearbox on the chopping drum for flexible use in short and long cuts
• Switching the drum speed takes a few minutes
• No downtime, no machine conversion, no up-front planning

Forming an integral part of the pulley, KRONE VariLOC is a gearbox that alters the speed of the chopping drum. By simply changing the drum speed from 1250 to 800 rpm using a standard open-end wrench, you can increase the chopping drum’s LOC range by up to 50%. This system allows operators to momentarily change from short to long chops and vice versa and meet different customer needs without a major changeover - this is the concept of OptiMaize. In conjunction with the roller conditioner with 105/123 teeth or with the disc conditioner, this technology turns the BiG X into a real all-round forage harvester that offers its owner and user maximum flexibility.

Great flexibility

The KRONE VariLOC is available for the MaxFlow drums with 28 and 36 blades. VariLOC is a mechanical gearbox that allows the MaxFlow chopping drum to produce the full range of chop lengths (OptiMaize S-XL) with 28 or 36 blades.

VariQuick

• Fast changeovers from grass 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 corn conditioner

VariQuick is the system that allows operators to converse BiG X very quickly from maize to grass. 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.

VariStream

• Consistently smooth performance despite inconsistent crop flows
• Extremely smooth running – also in lumpy swaths
• High throughputs
• Top quality chop
• Operator comfort to perfection

KRONE VariStream comprises a spring-loaded floor beneath the chopping drum and a spring-loaded back plate in the crop accelerator housing.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.

StreamControl

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

The crop throw is controlled from the cab by adjusting the door in the backplate on the crop 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

• Headers are swapped easily
• Convenient attachment and removal
• Very short set-up times
• Compact combination
• Maximum safety

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.

KRONE EasyFlow 300 S · 380 S

• Hard wearing pick-up without cam track, six rows of tines in W-arrangement
• Automatic pick-up speed adjustment to the current driving speed
• Gauge wheels on the sides and at the rear ensure perfect ground following
• Intake area lined with replaceable wear plates
• Quick header attachment thanks to curved round steel bracket

The camless EasyFlow 300 S and 380 S pick-ups have neither guide rollers 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.

KRONE XDisc

• Direct cut headers with 6.20 m or 77,10m working width
• High throughput, low power requirement
• KRONE EasyCut mower technology that is 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.
