The high linear speed combined with the high level of overlap between tools ensures high-quality shredding. Moreover, you can shred large quantities of residues with the large rotor diameter.
The rotor is fitted with four rows of tools to choose from universal knives with stubble pallets for better residue laceration as they are adapted for stubble and cereals, or long hammer knives for woodier material such as maize and sunflower stalks and for maintenance of hay fields.
Two working height control devices are available for these machines: semi-pivoting wheels or roller. Wide height-adjustable skids are available as option.
You will benefit from the maintenance-free rotor thanks to bearings that are greased for life and the free wheel in the central gearbox that needs no maintenance.
The linkage with yokes ensures a good rigidity of the tractor/tool link. A free wheel is integrated as standard in the gearbox and a sheet metal lining is available as optional equipment.
BK 230 and BK 280 shredders can be fitted with hydraulic offset of 40cm to the right to shred in fields with obstacles: orchards, rocks, etc.
The BK 320 can be transported lengthways for passing narrow paths and roads at ease.
The rear hood can be lifted manually for better access to the rotor. Therefore, the shredding tools can be changed in total ease.
