Centaya Special harrow-mounted seed drill

1. Electric metering drive: The Centaya Special comes as standard with an electric metering drive and is controlled by AmaTron 4 or any other ISOBUS terminal. In conjunction with the electric drive, calibration is comfortable and fully automated. The electric drive also offers additional functions such as the pre-metering of the seed in field corners and the increase and decrease of the seed rate during operation. The Centaya features different signal sources for detection of the speed. In addition to the radar sensor, impulse wheel or GPS signal, the speed signal of the tractor can also be utilised.
2. Quick emptying: the emptying of the seed in the hopper is quickly and simply done via the quick emptying device which is easily accessible and fitted onto the seed hopper.
3. Emptying of residual amounts: for emptying any residual amounts, a slide is opened and the hopper contents emptied into the large calibration tray.
4. Easy exchange of the metering cassettes: the cassettes of the seed metering system can easily be exchanged. This allows the precise and gentle metering of all seed types and seed rates with excellent distribution along the row even at high forward speeds.

Special metering cassettes for different application rates precisely and gently deliver the seed up to the distributor head. The 3 metering cassettes supplied as standard cover up to 95 % of all seeds. Additional cassettes are available e.g. for maize or specialist crops. The interchangeable metering cassettes are suitable for the following application rates: fine seeds (from < 1.5 kg/ha), medium-sized seeds (approx. < 140 kg/ha), normal seeds (approx. > 140 kg/ha).

1. 7.5 ccm: e.g. for linseed, poppies
2. 20 ccm: e.g. for rape, stubble turnips, lucerne
3. 100 ccm: e.g. for catch crop mixtures
4. 120 ccm: e.g. for green manure, maize and sunflowers
5. 210 ccm: e.g. for barley, rye, wheat
6. 600 ccm: e.g. for spelt, oats, wheat

AMAZONE offers Comfort-Pack 1 with TwinTerminal 3.0 for the electric metering drive in combination with ISOBUS to further simplify calibration and residue emptying. The TwinTerminal is mounted directly in the SmartCenter instead of the calibration button. The location of this offers a decisive benefit: the driver can now carry out the calibration check and input the data directly at 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.

The segmented distributor head is arranged behind the seed hopper directly above the coulters. This arrangement ensures a short conveying time for the seed.

The optional electric half-side shut-off helps to reduce any over-sowing on the headland or round the field border and thus saves seed. Half-side shut-off enables the machine to be comfortably switched off via the terminal in wedge shaped fields or steeply angled headlands. Additionally, via GPS, automated switching of half the working width is possible.

Either when using the electric half-side shut-off or during a tramline bout, the seed rate is reduced automatically.

The benefits:

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

With the aid of the tramline shut-offs, in total up to six seed rows per side can be switched off. The correspondingly wide tramline wheel tracks are suitable for tyre widths up to 1,050 mm on a 15 cm row spacing or 875 mm on a 12.5 cm row spacing depending on the following crop husbandry tractors. In this way AMAZONE takes into account the move towards those crop husbandry tyres getting wider and wider. The row spacing can be increased to hoe cereals by switching off every second row.

The hydraulic fan drive provides comfortable fan speed adjustment. The fan speed is set conveniently and independently from the engine speed, so that the revs always remain constant and run in the optimal speed range. The blower fan can also be equipped with an air intake screen to reduce the dust load.
