The technology | Metering

The metering makes the difference

Simple, central and convenient adjustment. Perfect metering.

Accurate metering drive
The metering system is suitable for all seeds and sowing rates from 1.5 to 400 kg/ha. The metering cassettes are specifically designed for the crops concerned. For example, rubberised, flexible cassettes are available for sowing legumes. They protect vulnerable seed from breaking and thus from impairing their germination capability.

Metering cassettes for different seed types

The change from fine seeds to normal seed is carried out by simply replacing the metering cassettes – quickly and without the need for tools, even when the seed hopper is full. Up to 95% of all common seed types can be sown using the metering cassettes supplied as standard.

1.    7.5 ccm for oil seed rape, linseed and poppies
2.    20 ccm e.g. for oil seed rape, stubble turnips, lucerne
3.    100 ccm for very low cereal seed rates
4.    120 ccm for green manure, maize and sunflowers
5.    210 ccm e.g. for barley, rye, wheat
6.    350 ccm for fertiliser
7.    600 ccm e.g. for spelt, oats, wheat
8.    660 ccm for peas and beans


Comfort-Pack 1 with TwinTerminal 3.0

The user-friendly TwinTerminal

In order to make pre-metering, calibration and emptying of any 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 near the metering unit. This position offers a decisive benefit: 

the driver can now perform the calibration operation and input the data from that calibration directly into the machine and no longer has to repeatedly get on and off the tractor. The TwinTerminal 3.0 consists of a water- and dust-proof housing with a 3.2" display and 4 large keys for control.

Segmented distributor head with electric half-side shut-off

The segmented distributor head provides huge flexibility for the pneumatic seed drill. Asymmetrical tramlines can be implemented without any undesirable seed rate reduction on the other half of the machine. The segmented distribution head can be used in conjunction with electric half-side shut-off. The half-side control is located directly inside the distributor head. In combination with Section Control, or the GPS-Switch automated part-width section control from 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 overlapping saves seed
  • Minimisation of dust creation inside the seed hopper because no seed is rerouted

Seed tube monitoring

Another useful system to assist the driver is the optionally available seed pipe monitoring which detects immediately any blockages down at the coulter and in the seed tube. Mounted directly behind the distributor head, sensors monitor the seed flow in the seed pipes. Incorrect switch-over of the tramline rhythm is automatically detected by the system. Especially on long working days, the monitoring is an elegant solution to help keep an eye on the working performance.

Hydraulic fan drive

The new high output blower fan is characterised by a low oil flow requirement of 21 l/min at 3,500 rpm as well as minimal noise generation.
