Precea-TCC trailed precision air seeder

Singling with SmartControl – for precise seed placement 
Over-pressure in the singling chamber pushes the grains 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 setting is done automatically by SmartControl to help the driver.

The benefits: 

• The stress on the driver is reduced, since the SmartControl constantly handles the adjustment of the 3 seed stripper fingers. 
• An increase in yield, since doubles and misses are avoided. 
• Savings in time, since manual set-up is not necessary.

ElectricDrive – electric drive of the over-pressure singling 
ElectricDrive utilises a separate electric motor for each over-pressure singling unit. The seed rate can thus be adjusted very easily using the terminal. An activation button on each sowing unit makes it possible to check each individual singling disc.

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: 

• Operation can be carried out exclusively using the tractor's electronic system, 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.

"As the chamber rotates in step with the perforated disc, energy-consuming friction on the pressure chamber seal is avoided."

The singled grains are fired precisely
As soon as the singled seeds reach the outlet, the contact pressure is broken 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 pulse of the Precea - the firing of each individual 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 e.g. the intelligent SmartControl stripper adjustment,.

One machine - 9 crops. Whether it be maize, oil seed rape, sugar beet, soya beans, sorghum, field beans, pumpkins, sunflowers or cotton – the Precea-TCC singles the 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-TCC across the widest variety of single-seeded crops. 

Because: the seed singling system of the Precea-TCC can be changed over to use different singling discs without any 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 centralised 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 by its use in various different sowing periods
• Simple replacement of the singling discs
