The WS 320 BIO shredder specialises in harvesting energy crops or intermediate energy crops. These dedicated crops are annual or perennial crops whose main objective of their establishment and harvest is energy recovery. These crops (miscanthus, switchgrass, sorghum...) also have many associated environmental benefits such as favoring biodiversity, water purification or soil erosion prevention. The WS 320 BIO offers incomparable advantages compared to other harvesting systems.

Your Benefits

Benefit with this harvesting system

A winning practice!

When compared to self-propelled forage harvesters or mowing and baling in separate steps, the WS 320 BIO stands out with the following assets: only one person necessary for the entire harvesting process; simpler transport logistics; less space needed for bale storage especially if baled with a high-density baler into square bales; reduced fuel requirements; less soil compaction due to less passages of large machines over the field.

One passage, three operations

A swath is formed by and auger behind the rotor. It is driven by a hydraulic motor directly connected to the tractor. The speed can be adapted to working conditions (quantity of vegetation, groundspeed). The shredded material is evenly distributed through the central opening at the back of the shredder. This prevents the tractors wheels from driving over the perfectly formed swath.

Shredding adapted to your harvested material

Adapt the rotor speed

The speed of the Y-knife rotor is reduced to obtain a shredding length of more than 15 cm in order to bale the residues. If you want to shred more finely, we recommend using a rotor on the baler. The roller can be adjusted to the desired cutting height of 4 to 15 cm.

Easier grasp of tall and dense crops

For a better grasp of the crops, which are generally tall and dense, the shredder has a hydraulically adaptable front cover and reel. The WS 320 BIO is suitable for all types of vegetation with high volumes. It
can even work in difficult conditions with lodged crops.

Coarse shredding of residues facilitates swathing and baling

The coarse shredding of biomass improves the grasp of plants by the baler. The swath formation is then carried out by the auger placed behind the rotor. Suitable knives on the baler will reduce the size of residues even more significantly before baling.

Proven robustness and reliability

A solid structure for a robust machine

The WS 320 BIO energy crop shredder has a thick sheet metal lining and two beams to provide robustness and reliability in all conditions and especially when shredding tall, dense and woody crops.
