Precea precision air seeder

The seed hoppers each hold 55 l or 70 l and are very easy to fill. The hopper lids can be conveniently opened with one hand, so that they can easily be filled from bags. A filling aid, that guides the seed safely into the hopper and makes the filling process even easier, is optionally available. Emptying of residual amounts is particularly quick, easy and clean.

The low level sensor, fitted as standard, warns of the fill level via the terminal at an early stage.

The benefits: 

• Good accessibility 
• One handed operation of the lid makes the filling process easier 
• Clever and clean emptying of residual amounts from both sides by using the seed chute

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 mechanical stripper finger setting allows fine adjustment of the strippers in order to optimise the seed placement accuracy. Doubles and misses are thus avoided, which increases the yield.

The electric stripper adjustment allows convenient setting of the scrapers from the operator terminal in the tractor cab.

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 SpeedShaft mechanical drive facilitates forward speeds of up to 12 km/h, even for entry-level models, without compromising the longitudinal distribution. Drive is provided by the Flex shaft.

Advantages of SpeedShaft:

• Maintenance-friendly, as all components are provided with life-long lubrication
• Output increase of up to 25 % compared to other mechanical systems
• Smooth running, even at high working speeds of up to 12 km/h

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 very conveniently be 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

Maximum precision – individual row shut-off 
The option of individual control of the sowing units enables each row to be individually switched on and off with the electric drive. This has particular advantages in wedge shaped fields and on the headland. More information can be
found on page 50/51.

Maximum flexibility with the highest work rates 
No matter whether it is used for conventional or mulch sowing, the PreTeC mulch sowing coulter is perfect for precision sowing. Benefit from the first-class, consistent seed placement accuracy and use it to increase your yield. The Precea facilitates high work rates due to its high accuracy, in particular at high working speeds of up to 15 km/h.

The benefits: 

• High operating comfort 
• Minimisation of any downtime 
• Time saving during regular maintenance

Even field emergence 
The mulch sowing coulter (weighing 120 kg on its own) can be pressed down further by a spring with a maximum force equivalent to 220 kg. Via a hydraulic cylinder, coulter pressures of up to 350 kg are possible. This ensures smooth running and even field emergence under the hardest of conditions. The complete mulch seeding unit is reliably guided by two large carrying rollers. Soil opening is performed by a double disc unit and a following furrow former. Once the seed has been embedded in the soil by the catcher roller, the V-pressure rollers follow to close up the furrow again.

The mechanical coulter pressure adjustment can be used to adjust the coulter pressure very easily and effectively via a tension spring with a series of notches. Up to 100 kg of extra coulter pressure can therefore be generated in addition to its own weight of 120 kg. Another increase of 15 kg is possible in the wheel tracks.

The coulter pressure can be adjusted even more easily and comfortably via the hydraulic coulter pressure adjustment. The coulter pressure can be adjusted to a pressure of up to 350 kg via the operator terminal, even while driving. The SmartForce automatic coulter pressure regulation also ensures that all coulters are automatically adjusted, even in different soil conditions.

The good accessibility to the seeding unit ensures high operating comfort. A multitude of adjustment options allow adaptation to all requirements.

The benefits: 

• Increased yields and an increase in the sowing quality as a result of the effective singling 
• More adjustment comfort due to tool-free operation 
• Higher flexibility due to the extensive range of optional equipment for the all-rounder coulter

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.
