Carbide counterblade for the Forage Harvesters BiG X

The low-wear carbide counterblade for the BiG X forage harvester ensures consistently high chop quality and a longer service life. 

Spelle, December 2025: KRONE BiG X forage harvesters can be used universally for many types of crops. Regardless of whether harvesting maize, grass or various whole plants, the cutting tools of the forage harvester are subject to a certain amount of wear and tear sooner or later, depending on the intensity of use. In addition to the blades of the chopping drum, wear and tear also affects the counterblade which is partly responsible for optimum chop quality. To ensure consistently high quality of the chopped material and a significantly longer service life, KRONE now offers an extremely wear-resistant counterblade equipped with carbide blocks.

Sharp and stable cutting edge
The carbide is sintered tungsten carbide and cobalt, one of the hardest materials in the world. To ensure optimum bonding to the steel body, the carbide is applied to the specially designed steel body using a special soldering process. Individual carbide blocks are soldered along the cutting edge and these blocks ensure that the cutting tools remain sharp. 
This carbide tipping delays the rounding process many times over compared to a conventional counterblade. This also has a positive effect on the blades which remain sharp for longer and ensure a long-lasting chop quality when used with different crops. Additional carbide blocks prevent the surface of the counterblade from being eroded; this also contributes to improving its service life. 

Clever replacement increases service life 
When the counterblade is used in grass or for cutting GPS, the abrasive stress is higher and the counterblade is subject to greater wear than in maize. KRONE therefore recommends the following method of use: After initial use in maize, the same side of the counterblade should then be used in grass and GPS. Then the side of the counterblade can be changed so that it can be used first in maize and then again in grass and GPS. This ensures that the cutting edge wears down very evenly, resulting in an extremely long service life over several harvest years.

Conclusion: The carbide used significantly reduces wear compared to conventional counterblades. This positive effect significantly increases the service life of both the counterblade and the chopping drum blades, thereby ensuring a consistently high chop quality for the various crops. Thanks to the long replacement intervals for the cutting tools, assembly times and associated costs are also reduced. The high quality of the materials used is therefore reflected in the consistently high quality of the chopped material. 

Quickly read

• Longer service life thanks to carbide: The new counterblade with carbide blocks is extremely wear-resistant and ensures a consistently high chop quality.
• Heavy-duty cutting edge: Sintered tungsten carbide and cobalt guarantee a stable, sharp cutting edge – soldered on using a special process.
• Optimised usage recommendation: Cleverly changing sides according to the crop type (maize, grass, GPS) ensures that the counterblade wears evenly and lasts longer.
• Less wear and tear, lower costs: The new counterblade also protects the drum blades, reduces assembly times and lowers operating costs while maintaining a consistent chop quality.
