Yield at harvest is influenced by precision seed placement. Regardless of whether you have light, heavy, dry or moist soil - optimum placement of the seed is critical for a satisfactory harvest.
Central coulter pressure adjustment with orientation scale
Even coulter pressure system
for the same pressure on front and rear coulters.
Perfect seed slot – precise depth control
Consistent row spacing
Coulter arms are secured using large clamp mounting on the coulter rails. Wide coulter arm mountings with replaceable bushes. Ability to ride over foreign bodies with up to 18 cm (7.09 inches) movement upwards. Coulter increments (positioning) of 30 cm (11.81 inches) ensures that large amounts of seed can pass through without blocking. Seed depth is controlled via the coulter pressure even without press wheels.
The PÖTTINGER disc coulter system for best seed germination
The scalloped disc coulters are suitable for mulch drilling and when there is a lot of organic matter. PÖTTINGERs diagonally tracking disc coulters open up the soil. The cast shoe, similar to a Suffolk coulter, removes wilted straw and crop residues from the seed placement area and forms a neat seed slot. This process guarantees even seed germination.
Different shapes of coulter with an inter coulter rail spacing (coulter offset) of 30 cm provide sufficient clearance even when operating in harvest trash.
Dished single-disc coulters, diameter 320 mm, with twin-race tapered bearings fitted with special seals. The rotating scrapers are adjustable and located to the rear so as to not reduce side clearance. Easily handles large clods.
The disc coulter is fitted with a long life hard wearing cast coulter point.
The Suffolk coulter is suitable for soil conditions where there are low amounts of organic matter. A protective flap closes each coulter automatically if the machine moves backwards. The spring-mounted coulter can fold back for reliable protection.
Wear-resistant cast coulter points.
Depth guidance rollers 250 x 40 mm available as option to limit depth and provide consolidation Straightforward pin-in-hole depth adjustment. Can be fitted and removed using hooks - no tools needed.
Uneven placement depth even in changeable soil.
Presses down to cover seed perfectly. Reliable germination even in dry conditions.
Large dimensioned inlet funnel for transition to seed tube (especially for spelt).
The creases in the inlet funnels provide maximum flexibility of the seed tubes to ensure perfect transport between the metering wheel and the coulter.
The telescopic seed tubes are stainless steel at the top and synthetic at the bottom to provide the lowest friction. This combination of materials greatly reduces the static charge in the seed grains.
