Your seed deserves the best placement

Part 2 - Dual-Disc coulters

The new VITASEM seed drills with Dual-Disc coulters from Pöttinger is world-class technology for future-safe arable farming.

How the Dual-Disc system works

enlarge	enlarge	enlarge
Coulter pressure adjustment	Consistent coulter pressure	Drill arm with pressure and depth guide roll
Coulter pressure of up to 50 kg possible. Coulter pressure is infinitely-variable and adjusted using a central spindle. Coulter pressure is adjusted by pre-tightening the rubber clamps	Drill arms are of equal length  in the first and second coulter row. Ensures uniform growth of seed grains across whole working width thanks to precise depth placement.	Each drill arm is mounted on a rubber clamp bearing so it is moveable and completely maintenance and wear free. The pressure roll takes control of depth regulation and can also be used to pack the soil down using an adjustable increase in pressure.

Seed material feed	Seed coulter	Placement depth
Combination of synthetic and stainless steel tube feeds seed to coulter without static charging. Distribution accuracy from top to bottom - from metering - is maintained on the way to the coulter thanks to the combination of materials so that seed is distributed precisely in the longitudinal direction. Uniform flow is ensured. The two different materials provide a smooth telescoping effect in the seed supply line. Internal wear is prevented as a result.	Dual-Disc coulter with a row spacing of 12.5 cm and a coulter gap of 25 cm for optimum plant distribution - an extremely reliable coulter system. This coulter system is also ideally suited for mulch drilling. Precisely matched offset disc positions create a narrow V-shaped seed groove for additional advantages: - Thanks to this special combination only a small quantity of soil is in motion, meaning that high travelling speeds are possible. - The seed is placed in the running direction of the coulter disc, ensuring precise placement in a tidily formed seed groove => uniform seed placement.	Placement depth is set centrally from the left and right of the machine. A fine scale is used to control the depth setting.

Promoting capillary water activity
The basis for promoting capillary water activity is provided by the recompaction of a leading packer roller. Independently of the working depth the seed coulter forms a tidy seed groove free of harvest trash to create ideal germination conditions.
