BiG X 680 | 780 | 880 | 1180
The KRONE OptiMaxx roller conditioners
- OptiMaxxroller conditioners with 250 or 305 mm (9" or 1') 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)
Perfect conditioning: The new OptiMaxx roller conditioners have their teeth slanted at a 5° angle.This slant produces a clearly higher shearing effect and perfect conditioning of the crop which receives a very intensive treatment both length- and sideways.
Maximum intensity: The two toothed rollers operate at a 30 % speed difference. This standard difference can now increase to 40-50 % to deliver 100 % conditioning and fracturing of long chops as produced by OptiMaize XL.
OptiMaxx 250 and 305
OptiMaxx 250: One for all – With the new OptiMaxx 250, KRONE presents a roller conditioner that off ers an even higher performance for the BiG X 680, 780, 880, 1180 models. This new development stands out for the following features:
- 250 mm diameter rollers have slanted teeth that give a unique shearing effect
- 10 % longer rotors and a 7 % higher rpm over the previous model.The greater length increases the friction surface area and ensures an effective crop intake, intensive conditioning and optimum cracking results
- Bigger and stronger springsapply a consistently high pressure on the crops
- The two rollers in the assembly have different numbers of teeth – 105/123 for medium and long chopping lengths – 123/144 for short and medium chopping lengths
- A standard 30 % speed difference with a 40 % of 50 % differential being an option for intensive fracturing and optimum cracking results
OptiMaxx 305 – An exclusive for the top model:
The OptiMaxx 305 is a unique feature on our flagship, the BiG X 1180.
This roller conditioner has a 55mm larger diameter than the OptiMaxx 250 hence matching the gargantuan appetite of this top-end monster machine.
- 305 mm diameter rollers with oblong teeth give a special shear effect
- A 11 % larger friction surface area and 20 % higher peripheral speed (than OptiMaxx 250) ensure an exemplary crop intake, intensive conditioning and optimum cracking amid high throughputs and long chop lengths.
- Stronger and more powerful springs apply a uniform, constant and high pressure on the crops
- A redesigned casing with beefier mountings ensures durability and longevity
- Temperature sensors on the roller bearings transmit the data to the operator terminal and ensure maximum safety
- Exemplarily easy to service and maintain thanks to large openings.Bearings, rollers and pulleys are replaced quickly and cleaning is as easy.
- The two rollers in the assembly have different numbers of teeth:
– 125/150 for medium and long chopping lengths
– 150/175 for short and medium chopping lengths - A standard 30 % speed difference with a 40 % of 50 % differential being an option for intensive fracturing and optimum cracking results
