Coulter expertise for the perfect seed slot

Precision drilling is dependent on closely-matched coulters for opening the seed slot, placing the seed and covering the seed again. A well-formed seed slot is essential for successful drilling.

The guarantee for optimum placement and uniform germination: PÖTTINGER delivers exactly the right coulters for your needs. Harvest residues are cut through reliably even at higher driving speeds thanks to the offset disc coulters.


DUAL DISC coulters

The large diameter DUAL DISC coulters with a diameter of 380 mm cut right through surface trash to form a uniform, tidy seed slot.

  • X-shaped configuration of the coulters for mirrored arrangement

  • Dynamic grain placement in a clean seed slot

  • Coulter offset of 320 mm provides a large clearance and smooth material flow even with large amounts of organic matter

  • Offset configuration of the coulter discs for reliable narrow seed slot formation and retention of the seed slot

  • Infinitely variable central adjustment of the coulter pressure between 40 and 120 kg

  • Because the coulter arms are all the same length, the identical coulter pressure is ensured on each coulter unit

  • Row spacing from 12.5 cm for the best plant distribution density (optional 16.7 cm)

  • 100 % sealed seed coulter bearings

  • Convenient central, hydraulic adjustment of the coulter pressure and the placement depth of the coulter rail

Press wheels for uniform placement depth

Each disc coulter is mounted on an independent parallelogram to ensure excellent ground tracking - even at high travelling speeds.

  • Large press wheels with a diameter of 380 mm

  • Each of the disc coulters is guided by a press wheel to ensure a precise and uniform seed placement depth.

  • In addition to depth control, the press wheels also ensure controlled consolidation of the soil and pressure on the seed.


Fertiliser or second type of seed

FERTILIZER PRO fertiliser coulter

Fertiliser or a second type of seed is applied by TERRASEM (Z) FERTILIZER universal seed drills using the maintenance-free PRO single-disc fertiliser coulter. Fertiliser is applied behind the disc harrow using these coulters and positioned between two seed rows (mid-row banding).

  • The PRO single-disc fertiliser coulter deposits fertiliser between the rows of seed at the same level as the plant root - wide rubber brackets on the box section frame prevent sideways movement to ensure precise row spacing.

  • Precision placement saves fertiliser, minimises unproductive losses and promotes faster development of the root mass for optimum yield.

  • The placement depth of fertiliser and seed can be set independently of each other.

  • Instead of depositing fertiliser, other seed material can also be sown using the FERTILIZER PRO coulter.
