Horsch SingularSystem

Summary coulter versions

The HORSCH SingularSystem is the technology for cereal singulation and precision sowing. With a similar design as the well-proven TurboDisc coulter it is additonally equipped with an integrated skid and height adjustable catching roller. The skid forms the seed furrow and guarantees an precise placement of the see. The catching roller guarantees a defined seed placement and an excellent seed-soil contact. To guarantee a smooth and exact mechanical singulation of the grains, even and clean seed is required.
In conditions with higher seed rates or seed that cannot be singulated, e.g. coarse legumes, the SingularSystem coulter can be equipped with the delivered Bypass or, for extremely high application rates, with a stainless steel fall tube. It then can be used as a ”normal” seed drill without singulation. With these two versions you achieve a preciser embedding of the seed due to the skid and the catching roller at the coulter.
With our Pronto 6 DC with double hopper two components can be applied in two horizons by means of the SingularSystem seed coulter with DoubleShot . With the Funck metering device or a stainless steel fall tube the seed is placed and via our DoubleShot system for example fertiliser is applied below it. Thus, fertiliser is applied efficiently and without any losses below the seed. This is particularly advantageous for the early development of many crops. Another asset of the DoubleShot system is that in dry conditions there is no direct contact between fertiliser and seed. Thus burns on the seedlings are prevented.

Seed coulter

• The design of the seed coulter and the main characteristics like the coulter pressure of up to 120 kg are identical to the well-proven TurboDisc coulter.
• Depending on the conditions an operational speed of up to 10 km/h is possible.
• The well-proven DoubleDiscs open the seed furrow. An integrated skid forms the seed furrow and guarantees an exact placement.
• A height-adjustable catching roller allows for a defined placement of the seed and creates the necessary seedsoil contact.
• After the catching roller the well-known press wheel closes the furrow and controls the depth of the seed coulter.

Seed

• To guarantee an undisturbed and exact mechanical singulation of the grains, the seed has to be even sized and clean.
• The homogeneity of the seed and thus, its suitability for the system can be determined by means of the HORSCH shaker box.
• Generally the grains should be in the second or third chamber of the shaker box.
• If the grains end up in the first or last chamber, this seed is not suitable for singulation (in this case the Bypass system can be used).

Singulation

• The structure of the central metering unit and the pneumatic system are identical to the conventional seed drills.
• The singulation of the grains is made by the Funck metering device on the seed coulter with up to 100 grains/sec.
• Singulation is carried out mechanically by crop-specific pockets in the singulation disc inside the Funck metering device.
• The desired seed rate in grains/m² and the thousand seed weight are entered in the terminal.
• The calibration test is carried out according to the well-known system.
• Every singulation disc is driven by an own electric motor (1 000 – 2 000 rpm), monitored by the software and controlled automatically depending on the operational speed.
• Depending on the seed rate 1, 2 or 4 pockets can easily be put into the singulation disc without any tools.
• Different pockets are available for wheat, rye, bayley, rape and peas.
• The seed is transported to the seed furrow via the fall tube.
• From an agricultural point of view the use of the system makes sense up to a seed rate of 250 grains/m². Beyond this limit the singulation effects are only marginal.
• In case of high seed rates, unsuitable seed or if catch crops are to be sown, the delivered Bypass system allows for sowing conventionally.
