Precea-TCC trailed precision air seeder

• Easy access provides quick and easy filling 
• High area coverage is possible thanks to a hopper capacity of 2,000 litres

Seed is delivered from the central hopper to the reception units above each sowing unit via an air stream. These reception units act as a small intermediate store for seed. The air stream stops automatically when the unit is full enough so that the internal colour-coded sieve is covered by seed. This also means that no more seed is conveyed from the central hopper to the sowing units. The air stream starts automatically when the amount of seed in each intermediate store has fallen sufficiently and the sieve can be seen again. Delivery of seed from the central hopper to the sowing unit restarts at this point. The Central Seed Supply System means that each row is constantly kept supplied with seed without the need for any electronic control.

The benefits:

• Time-saving seed filling thanks to an easily accessible central hopper 
• Top work rates and quick turn-round times as a result of the large hopper capacity

Reliably singled
The singling system works by using the overpressure principle. The pressure pushes the grain against the nap holes in the rotating centralised singling disc so that they are driven round. As they rotate, the grains under pressure pass three stripper fingers which reliably ensure just a single grain remains on each hole. Excess seeds are reliably stripped off, so that any doubles are effectively prevented. This is especially important for the accuracy of the seed placement.

1. Rotating disc
2. Singling disc

The key feature:

Due to the thoughtful design of the centralised singling unit, the singling disc and the singling pressure chamber are firmly connected to each other.

The advantages of this layout are huge:

• Metering is carried out exclusively via the tractor's electronic system due to the fact that only a low torque is required for rotation
• The seal, which is otherwise subject to excessive wear, is not loaded

The electric metering drive to the individual rows makes it also possible to maintain an evenly-spaced placement across the entire working width, even when driving round bends. The even spacing allows the plants to be adequately supplied with nutrients. This results in more uniform crops and ensures even ripening.

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

• Even field emergence thanks to the SmartForce automatic coulter pressure regulation 
• High level of flexibility due to the wide range of application in both conventional and mulch sowing 
• Easy access and tool-free adjustment provide maximum comfort

AMAZONE offers the SmartForce automatic coulter pressure regulation system for the folding Precea precision air seeder as an add-on to the hydraulic coulter pressure adjustment.

The particular feature with this system is that the driver does not stipulate the coulter pressure, but rather sets the contact force in the terminal. This contact force is checked by measuring pins in the field. The contact force varies due to different soil types, as the soil acts differently on the unit. The hydraulic system regulates the coulter pressure meaning that the placement depth remains constant. This means that the coulter pressure will be adapted to suit the various different soil conditions on the move. This makes it easier for the driver and results in a more even field emergence.

Simultaneous maintenance of a consistent placement depth and optimum pressure ensures high field emergence and provides the basis for good yields.

Maintaining a consistent placement depth on varying soils or with uneven reconsolidation is a particular challenge for the technology and the user.

SmartForce regulates the required coulter pressure on the basis of the contact force measured on the PreTeC coulter. This ensures that the intended contact force and the placement depth are maintained under all soil conditions.

SmartForce relieves the driver and enables a consistently high quality of work under all conditions.
