WN HD TANDEM knife roller is a reinforced version of the standard WNT machine designed for work in the most difficult conditions, equipped with a double ø 560 mm roller and HARDOX guillotine knives. The top cover is standard. The purpose of the roller is intensive shredding of plant mass along with crushing and partial covering. This accelerates the decomposition of residues, which is conducive to further work on postharvest crops.  The working depth of the machine is 2-3 cm (knife depth).

In the HD type machine, a high degree of shredding, crushing, and mixing of residues is achieved thanks to the use of an aggressive knife mounted on two rollers with a different number of knife rows on the circumference of the roller (7-row and 8-row roller). Thanks to this, during the passage, there is no overlap of cutting marks by cooperating rollers. This allows the roller to be used in demanding working conditions.
