Joker HD

Strengths of the Joker

  • Produces high quantities of fine soil within the germination zone
  • Efficient consolidation due to the double RollPack packer with high load-bearing capacity and excellent levelling effect for strip-consolidation
  • Less susceptible to failure in case of long harvest residues and shallow cultivation. Highest clearance and enough room between the disc rows and the packer.
  • Improved operational results with increased speed
  • Precise depth control due to front support wheels and double packer
  • High working performance with little draft requirement
  • High working speed in general
  • Good penetration with aggressive, serrated discs and maximum machine weight
  • Large transport chassis for fast and safe road transport

In which working conditions does the Joker perform well?

  • Shallow and fast stubble cultivation for quick germination of lost grain, interrupting capillary and ensuring incorporation of straw
  • From shallow and fast stubble cultivation after cereals to a 15-cm-deep cultivation after grain maize
  • Incorporation of long straw and difficult residues (cover crops, corn stubble)
  • Smooth incorporation of organic fertilisers (manure, cover crops)

Joker HD –

With large diameter discs

Strong points and advantages of the Joker HD

  • Shallow, intensively mixing stubble cultivation
  • Up to approx. 15 cm deep, intensively cutting and mixing cultivation with high quantities of for example grain maize residue
  • Large disc diameter of 62 cm with a 6-bolt fixing for a use in most difficult conditions, for example on heavy soils or if there are high quantities of harvest residues.
  • Concaved shaped discs for a constant cutting angle of 17°
  • Compact machine with high levelling effect
  • The discs are mounted in rubber elements resulting in an increased operating life and an improved adaption to the soil
  • The strong design of the frame is very stable for deep cultivation and high strains. The frame guarantees the necessary weight to ensure penetration.
  • Double RollPack packer with 55 cm Ø U-profile rings. Very stable and suitable for all types of soil. Resistant to stones even at high speeds. Linked packer rings for excellent self-cleaning.

Joker HD

Always a trump card in your hand

  • From shallow stubble cultivation after cereals to a 15-cm-deep cultivation after grain maize
  • Vertically arranged discs for very intensive mixing
  • Extremely resistant to cloggings due to the discs that are arranged in pairs and thus allow for large clearance
  • Compact design
  • Double packer with high load-bearing capacity and excellent levelling effect
