Cutterhead knives for forage harvesters

Cutterhead knives play a critical role in forage harvester performance. Which is why it’s so important to choose knives that fit, perform and last. Good knives have:

 

  • Sandblasted surface ensures precise clamping forces.
  • Induction-hardened cutting zone stays sharp longer.
  • Tough body minimises breakage risk.
  • Extended knife body supports retraction on object impact.

 

The John Deere® 7050 self-propelled forage harvester series you can choose from three cutterheads, depending on your crop and cutting conditions. The 40 and 48 knife heads are perfect for long grass, fibre crops and maize. The 56 knife head provides the finest chop (4 mm) and excellent quality maize silage, even in dry conditions.
