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.
1 Consistent coulter pressure up to 120 kg
2 Parallel linkage for exact placement depth
3 Consistent coulter pressure thanks to same-length coulter arms
4 Coulters offset by 320 mm for blockage-free operation
5 Exact depth control and consolidation
The large diameter DUAL DISC coulters with a diameter of 380 mm cut right through surface trash to form a uniform, tidy seed slot.
Harvest residues are cut through reliably even at higher driving speeds thanks to the offset disc coulters.
Dynamic grain placement in a clean seed slot
The inter coulter rail spacing 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 seed slot formation
Infinitely variable adjustment of the coulter pressure between 40 and 120 kg
Row spacing from 12.5 cm for the best plant distribution density (optional 16.7 cm)
Same-length coulter arms ensure identical coulter pressure on each unit.
An easily adjusted turnbuckle ratchet on the coulter rail is used to adjust seed placement depth on each section.
Each disc coulter is mounted on an independent parallelogram to ensure excellent ground tracking - even at high travelling speeds.
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 a second type of seed is applied on the TERRASEM FERTILIZER models using the 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.
Where fertiliser is deposited, it is also possible to deposit a second seed
