Precea-TCC trailed precision air seeder

Hydraulic tramline offset and telescopic axle

Wheel marks in the field inevitably reduce the actual cultivated area for the crop. Although switching off the rows in the wheel marks saves on consumables such as seed and fertiliser, it reduces the seed rate and thus the natural yield potential of the field. 

The intelligent tramline management on the Precea TCC with hydraulic tramline offset and telescopic running gear balances out this disadvantage by adapting the axle width to the row spacing. Or: This can be by just making a slight offset of the seed rows next to the wheel marks or a combination of both the offset and the drill track width. Full seed rate and damage-free subsequent applications in the crop without driving over seed rows for high yields on every field.

With a symmetrical offset, the slide cylinders are actuated simultaneously on both sides of the machine. A tramline is therefore created in only one pass. The maximum offset distance of a unit is 400 mm. The offset travel can also be reduced if the entire width is not required due to track width or tyre size.

The advantages of the hydraulic tramline offset

• Optimum yield potential since the seed rows do not need to be switched off, they are just displaced. 
• Relief for the driver by automatic detection and adaptation to make the tramline. 
• Lack of plant damage during subsequent working in the crop, as a result of the existing tramline. 
• Optimum fertiliser supply since the fertiliser coulter and the singling unit are displaced together.

The basic settings of the Precea TCC are largely made directly on the PreTeC mulch seed coulter without tools. The placement depth, the contact pressure of the press rollers and their opening angles for precise reconsolidation are very easily set using the numbered scales. The depth of the fluted disc wheel mark eradicators can also be adjusted without tools.

The coulter pressure, on the other hand, is set hydraulically via the ISOBUS control terminal - with the SmartForce option automatically based on the coulter pressure actually required during work.

Further settings such as folding and unfolding the coulter system, extending and retracting the telescopic axle, tramline control, individual row shut-off and CurveControl are also made electronically from the cab as per the ISOBUS standard. 

For other SmartFarming applications, such as the part-area, site-specific application of fertiliser or seed, individual row shut-off for either medium or the individualised start/stop times of each metering unit, an ISOBUS operating terminal that supports these functions is required, such as the AmaTron 4.

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.
