System Airstar: reliable metering drive – Simple adjustment and comfortable calibration

(1) ElectricDrive electric metering drive: The electric metering drive is regulated via any ISOBUS terminal. The calibration, in conjunction with the electric drive, is very comfortable and offers additional functions, such as, for example, pre-metering of the seed in field corners and the increase and decrease of the seed rate on the move. For detecting the forward speed of the drill several different signal sources are potentially available. In addition to the radar sensor or GPS signal, also the speed signal of the tractor can be utilised. Alternatively, the metering unit, and thus the seed rate, can be controlled fully automatically via application maps. (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 seed residues, 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.

The calibration concept

Convenient calibration via the SmartCenter on the left hand side of the drill thanks to the calibration button or, as an option, using the TwinTerminal 3.0. For this, the tray for the calibration is placed directly underneath the metering unit. Subsequently the calibration tray can be removed comfortably via the SmartCenter. Thanks to the intelligent integration of this function, the calibration tray can be removed only when the metering flap has been closed via the remote linkage. During the calibration procedure, the seed is delivered safely and cleanly into the calibration tray. Also decanting into the supplied folding bucket is done quickly, easily and comfortably. After calibration the calibration tray is simply, with its opening facing downwards, stored in the park position. With the standard digital balance, the calibrated quantity can be weighed reliably and accurately. Additional storage space in the SmartCenter provides sufficient room for the folding bucket and the digital balance.

SmartCenter

With SmartCenter AMAZONE offers a very simple and clear layout of the most important adjustments. The grain Placement depth and the coulter pressure are independently adjusted in the SmartCenter at the left hand side. Thanks to the universal operating tool the adjustments are quickly and simply done.

Metering cassettes for any type of seed

Special metering cassettes for different application rates precisely and gently deliver the seed up to the distributor head. The three metering cassettes supplied as standard cover up to 95 % of all seeds. Additional cassettes, for instance for maize or special crops, are also available. The interchangeable metering cassettes are suitable for the following application rates: fine seeds (approx. < 15 kg/ha), medium sized seeds (approx. < 140 kg/ha), normal seeds (approx. > 140 kg/ha).

Segmented distributor head with electric half-side shut-off

The segmented distributor head is located behind the seed hopper and 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. Via the half-side shut-off, the drill metering can be comfortably controlled via the terminal in wedge shaped fields or on a diagonal headland. Additionally via GPS, the 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

Variable tramline control

With the aid of the tramline shut-offs, in total up to six seed rows per side can be switched off. The resulting wider tramlines are well-suited for the use of husbandry tractors with tyre widths up to 1,050 mm at a row spacing of 15 cm and 875 mm at a row spacing of 12.5 cm. In this way, AMAZONE takes into account the demands due to wider and wider husbandry tractor tyres. Whilst shut off when tramlining, the seed rate is automatically reduced.

Operating position and speed signals

The standard equipment level of electric drive offers the possibility to freely choose the signal source for both the speed and also the operating position. In this way, depending on the application, a flexible choice between the different sources is possible.
