The universal chopping drum

• For grass, pre-wilted material, whole crop silage and maize
• Chopping drums with 20, 28 or 36 blades
• Plenty of carrying space under the blade carriers: high throughput and smoother running even on uneven swaths
• Blades quick and easy to insert and remove

OptiMaize XL: The 20-blade drum cuts the kind of long lengths that are called for in some countries.

This 28-blade unit is the universal drum. Used with just half the number of blades, it is perfect for producing long chops.

Handling massive throughputs and providing a wide range of cutting lengths, this 36-blade drum will earn its keep in no time. Remove half the blades and the unit is perfect for long chop applications.

More space for more crop: The blade carriers are arranged and designed to allow plenty of space under the blades. This extra carrying space means higher throughputs and smoother running, particularly in grass.

The special drum for short LOCs

• The Biogas drum has 40 chevron-style blades and the Super-Biogas drum has 48
• High cutting frequency
• High inertia
• Fewer overlengths
• High gas yields

Higher output, lower costs: Working with short LOCs, the KRONE Blade Biogas drum boosts throughputs by almost 25% over the 28-blade standard drum. What’s more, fuel consumption drops by up to 16% per tonne of chopped crop.

40-blade drum: With its higher throughputs and lower fuel consumption per tonne of chopped maize, the 40-blade Biogas cylinder pays for itself in no time. The short stalks increase the efficiency of the biogas fermenter. With the higher gas yield per m³ of crop, less acreage is needed for biogas production.

48-blade drum: The Super Biogas drum with 48 blades is specially designed to meet the needs of modern biogas plants. Delivering a 20% higher cutting frequency than the 40-blade drum and a theoretical LOC ranging from just 2 to 12 mm, this Biogas drum produces an even shorter chop, boosting gas yields and throughput at the biogas plant even further and reducing fuel consumption per tonne of crop with the same LOC.
