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.

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.

Smooth-running, rugged and reliable

The high-capacity double disc coulter ensures clean and reliable placement. The double disc coulter runs smoothly and deposits the fertiliser in front of the PreTeC mulch coulter. The double disc coulter is completely maintenance-free and fulfils the highest demands.

The benefits: 

• Reduced soil throw ensures a very smooth running 
• High service life thanks to the rugged and proven large-area seed drills 
• Stepless working depth adjustment 
• Exchangeable protection plate
