Precea precision air seeder

The heart of the Precea seeding system

Seed by seed, embedded precisely in the soil at the correct depth. Achieve ideal plant emergence when single-seeding with the AMAZONE Precea and its precise singling system.

The singling system – for exact seed placement

Over-pressure in the singling chamber pushes the seed up against the nap holes in the rotating singling disc so that they are carried round. As they rotate, the seeds, held in place under pressure, run past 3 stripper fingers which reliably knock off of any excess seed and ensure the singling of a seed onto each hole. Doubles are effectively prevented. The stripper fingers are adjusted mechanically, electronically or automatically with the SmartControl. 

The over pressure singling is driven electronically by the ElectricDrive.

The key feature

Thanks to the ingenious design of the centralised singling unit, the singling disc and the singling chamber are fixed together.
The advantages of this layout are huge:

• The operation can be carried out exclusively using the tractor's power supply, due to the fact that only a small amount of torque is required for rotation
• The seal, which is otherwise subject to excessive wear, is not loaded

The singled seeds are fired precisely

As soon as the singled seeds reach the outlet, the contact pressure is interrupted by a roller that covers the hole and the seed is shot past the opto-sensor into the propulsion channel and thus into the soil.

Opto sensor with infrared sensor - reliable monitoring "seed by seed"

The pulsating heart of the Precea - the shooting of each individually singled seed - is registered by the infrared sensor in the opto-sensor and transmitted as a signal to the AmaTron 4. The signal is then processed for use by, for example, the intelligent SmartControl remote stripper adjustment.

The standard electric stripper adjustment allows convenient setting of the stripper fingers from the operator terminal in the tractor cab. Alternatively, you can switch to automatic stripper adjustment via SmartControl in the terminal.

SmartControl – automated stripper finger adjustment for the Precea Super

In order to relieve the stress on the driver and avoid unintentional misses and doubles, AMAZONE offers the SmartControl automated stripper finger adjustment on the Precea Super.

The benefits:

• The stress on the driver is reduced, as SmartControl handles the adjustment of the seed strippers
• An increase in yield, as doubles and misses are avoided
• Savings in time, as any manual set-up is not necessary

The ElectricDrive option provides a separate electric motor for each overpressure singling unit. The desired seed rate, fertiliser rate and the micro-granular applicator can thus be very conveniently controlled via the terminal. One activation button per sowing unit makes it possible to check the centralised singling disc.

Advantages of ElectricDrive: 

• Accurate sowing in wedge shaped fields and on the headland in combination with the automated individual row shut-off 
• Flexible increase in the seed rate across the entire working width
• Working speeds of up to 15 km/h 
• Activation buttons for checking the centralised singling disc

The option of individual control of the sowing units enables each row to be individually switched on and off via the electric drive. This has particular advantages in wedge shaped fields and on the headland. 

One machine - 9 crops. Whether maize, oil seed rape, sugar beet, soya beans, sorghum, field beans, pumpkins, sunflowers or cotton – the Precea singles each seed by seed with precision and reliability

Increasingly complex crop rotations are finding their way into agriculture. It is often necessary to adapt to suit the soil conditions, actual nutrient consumption or the nutrient release from the previous crop, seed rate, weather and climate changes, nutritional trends and market opportunities, even at short notice. The one constant: the precise singling of the Precea across the widest variety of single-seeded crops. 

Because: the seed singling system of the Precea can be changed over to use different singling discs without the need for tools within a very short time.

The versatility of the Precea allows different crops to be sown both within the same and different sowing periods. This reduces the unproductive time over the course of the year, thus increasing the efficiency of the Precea and other associated fixed costs. 

Contractors can react flexibly to customer requirements and offer a wide portfolio of precision seeding.

The singling discs are customised for different operating conditions or seed characteristics, such as different thousand grain weights and forward speeds.

The benefits:

• Full flexibility for the widest range of crops.
• Higher machine utilisation through continuing use in different sowing periods.
• Simple replacement of the centralised singling discs.
