Metering | Conveying system

Flexible conveying system concepts – From a simple seed hopper to a twin-chamber hopper with split conveying system

1. Sowing

  • Sowing with one seed type using the RoTeC pro coulter or the TwinTeC+ coulter


2. Single-Shoot

  • Sowing of seed and fertiliser / second seed type in the same seed furrow using the single-shoot method


3. Double-Shoot

  • Sowing of seed and fertiliser / second seed type in two different seed furrows using the double-shoot method


4. Single-Shoot + Double-Shoot

  • Combination of single-shoot and double-shoot methods

Cirrus with simple seed hopper

AMAZONE offers the Cirrus Compact and the Cirrus with a hopper capacity of 3,000 l to 3,600 l for the simple and effective sowing of just one crop.

Cirrus-C with twin-chamber hopper and single-shoot conveying system

In addition to the single-tip, open hopper version of the Cirrus, the Cirrus-C also offers a split twin-chamber hopper and an additional conveying system. If sowing also requires the simultaneous application of alternative materials such as fertiliser, the Cirrus-C, in 4 m to 6 m working widths, offers the option of metering two different materials at the same time. The Cirrus-C has a hopper capacity of 4,000 l with a 60:40 split. These machines sow the second crop or fertiliser directly with the seed in one furrow using the single-shoot method.

Cirrus-CC with twin-chamber hopper and double-shoot second conveying system

Cirrus-CC with twin-chamber hopper and double-shoot second conveying system

With the Cirrus-CC, AMAZONE is providing an additional Cirrus model with a conveying system concept that allows for the delivery of two different materials. The Cirrus-CC, as well as the Cirrus-C, has a twin-chamber hopper with 4,000 l hopper capacity and two independently operated, electrically- driven metering units. In addition to the level of equipment on the Cirrus-C, the Cirrus-CC has a separate metering unit and a FerTeC single disc coulter

Due to the additional FerTeC single disc counter, which is located in front of the tyre packer, the Cirrus-CC can sow two materials at different seed rates at the same time. This means that any possible sowing combination is possible from simple sowing, to double-shoot, to a combination of double-shoot and single- shoot with simultaneous single-shoot. The Cirrus-CC concept sets completely new standards in sowing technology.

The Cirrus-CC – an unmatched multi-talent

Stay flexible with maximum comfort!
The different combination options of the conveying system on the Cirrus-CC results in a multitude of arable farming options for the user. Separate placement makes it possible, for example, to bring out much larger amounts of fertiliser when sowing.

Another interesting option is the combination of fertiliser delivery using the single-shoot and double-shoot method. It is possible, for example, to sow small amounts of fertiliser directly with the seed, which has a very strong impact on early development. In order to prevent damage due to acid burns, the remainder of the fertiliser can then be placed next to and below the seed row by an additional coulter.

If required, it is also possible to use the add-on GreenDrill 501 to meter and distribute a third crop.

Benefits of the Cirrus-CC:

  • Sowing with one seed type using the RoTeC pro coulter or the TwinTeC+ coulter
  • Sowing of seed and fertiliser / second seed type in the same seed furrow using the single-shoot method
  • Sowing of seed and fertiliser / second seed type in two different seed furrows using the double-shoot method
  • Combination of single-shoot and double-shoot methods

Accurate metering drive

The metering system is suitable for all seeds and sowing rates from 1.5 to 400 kg/ha. Over-sized metering cassettes produce a low peripheral speed protecting the seed from damage. Conversion from fine seeds to normal seeds is done in seconds by exchanging the metering cassettes. They can even be changed when the seed hopper Is full. The three metering cassettes supplied as standard cover up to 95 % of all seeds. Other metering cassettes, for instance for maize or specialist crops, are also available.

1. e.g. for rape, stubble turnips, lucerne²
2. e.g. for barley, rye, wheat¹, ²
3. e.g. for spelt, oats, wheat¹, ²
4. For rape, linseed and poppy seed¹, ²
5. For green manure, maize and sunflowers
6. For fertiliser
7. For peas and beans

¹Standard for Cirrus with working widths up to 4 m
²Standard for Cirrus with working widths from 4 m

Comfort-Paket 1 mit TwinTerminal 3.0 (1) TwinTerminal_001_d1_141222

Comfort-Pack 1 with TwinTerminal 3.0

In order to make pre-metering, calibration and emptying of residual amounts even easier, AMAZONE offers Comfort-Pack 1 with TwinTerminal 3.0 for the Cirrus in conjunction with an ISOBUS terminal. The TwinTerminal is mounted directly on the seed drill next to the metering unit. This position offers a decisive benefit: The driver now can carry out the actuation and data input for the calibration procedure direcly at the machine and thus the repeated climbing up and down into the tractor is no longer necessary.

The TwinTerminal 3.0 consists of a water and dustproof housing with a 3.2 inch display and four large operation keys.

Segmented distributor head with electric half-side shut-off

The segmented distributor head provides huge flexibility for the pneumatic seed drill. With immediate effect, asymmetrical tramlines can be carried out without an undesirable seed rate reduction on the other half of the machine. The segmented distribution head facilitates the electric half-side shut-off. The half-side shut-off is located directly in the distribution head. In combination with Section Control or the GPS-Switch automated part-width section control by AMAZONE, the use of the half-side shut-off can lead to considerable savings, as overlaps and unsown areas are avoided.


The benefits:

  • Electric half-side shut-off
  • Reduction in overlap saves seed
  • Minimising dust creation inside the seed hopper because no seed is rerouted

Variable tramline control

With the aid of the tramline shut-offs, in total up to six seed rows per side can be switched off. Appropriately wider tramlines are suitable for the use of crop-care tractors. In this way, AMAZONE takes into account the demands of wider and wider tyres on the crop husbandry tractor. Whilst shut off when tramlining, the seed rate is automatically reduced.

Seed tube monitoring

An additional useful assistance system is the optional seed tube monitoring which immediately detects blockages at the coulter and in the seed pipe. Directly behind the distributor head, sensors check the seed flow inside the seed tubes. The system automatically detects when the drill is tramlining. Especially during long working days, the monitoring is an elegant possibility to check the performance.
