  • 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
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
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
The KRONE chopping assembly
  • KRONE chopping drums with 20, 28, 36, 40 or 48 blades
  • High inertia: enclosed 660 mm (2'2") diameter drums
  • Bespoke 800 mm (2'7") wide drums for the BiG X 680, 780, 880 and 1180 models
  • Extremely fuel-efficient courtesy of a high inertia and pulling cuts

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
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
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

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.

  • Optimaize is a versatile and unique system
  • Gearbox on the chopping drum switches flexibly from short cuts to 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.

  • 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.
