The Turbo or Directa coulters currently used in
Argentina have been substituted for the American
market by the RADIAL COULTER BLADES, a coulter
with a similar performance but a different wave
layout.

RADIAL COULTER BLADES

• The Radial design features LINEAR and
  ASYMMETRICAL waves which cut progressively with
  minimum effort and reduced soil stirring but
  outstanding trash cutting capacity.

12
RADIAL COULTER BLADE
MAIN ADVANTAGES Outstanding cutting
capacity Minimum vertical penetration
force Minimum stirring Higher seeding
speed Superb self-sharpening capacity More
furrow humidity These features make the Radial
Coulter the best choice for trash cutting with
minimum soil stirring.
13
Straight asymmetrical waves

• Radial Coulters differ from the standard
  sinusoidal wavy coulters in the sense that the
  latter cause greater soil stirring and humidity
  loss.
• Standard wavy coulters are neither
  recommended for areas where humidity is scarce
  nor for excessively damp soils as the soil may
  get stuck to the coulter surface.
• Straight asymmetrical waves produce less
  stirring, keep the soil humid for a longer time
  and allow for longer seeding periods. They also
  perform better on damp soil as sticky soil comes
  off the straight waves easily.

14
A BETTER CHOICE

• Turbo coulter blades scatter a significant
  amount of soil due to the fact that the
  tangential waves produce a spoon effect which
  causes upwards, backwards and side soil
  spreading.

15
A BETTER CHOICE
The straight waves on Radial coulters, on the
contrary significantly reduce soil spreading
outside the trench with improved trash cutting
capacity. The coulter wave foldings cut a neat
strip of soil with minimum soil disturbance.
