The new Cirrus-CC models, in working widths from 4 m to 6 m, offer an additional conveying concept which enables the individual placement of two different materials.
The Cirrus-CC features the 4,000 l pressurised tank with its two electric metering units but, in addition to the Single-Shoot system on the Cirrus-C, the new Cirrus-CC is equipped with a second conveying line and the additional FerTeC single disc coulters in front of the tyre packer. So, the two different materials being conveyed can be sown at different seed rates and placed in different seed furrows.
With the Cirrus-CC, the following combinations are possible:
- Sowing of just one seed variety via the RoTeC pro or TwinTeC+ coulters
- Sowing seed and fertiliser (or a second crop) in the same seed furrow via the Single-Shoot system
- Sowing seed and fertiliser (or a second crop) in two different seed furrows utilising Double-Shoot mode
- A combination of both Single-Shoot and Double-Shoot modes
For the end user, these different combinations result in a variety of options that can be utilised in modern arable farming. Due to the alternative placement position, for instance, significantly larger amounts of fertiliser can be applied in addition to the seed. Especially in areas where there is a short growing season, where there is a higher water deficit during the growing season and during spring sowing, this principle plays an increasingly important role worldwide.
But also the possibility of combining the fertiliser application in both Single-Shoot and Double-Shoot is an interesting opportunity.
A small amount of fertiliser can be placed directly with the grain which promotes the growth of the plant. The remainder is placed via the FerTeC coulters to the side and underneath of the seed row to avoid any burning of the seed.
Furthermore, due to the FerTeC coulters, a mix of seed sizes can be established significantly easier. Using this technology, fine seeds can be kept separate from coarser seeds and light dependent germinating seeds can effectively be sown separately at different placement depths from darkness dependent germinating seeds. With the Cirrus-CC, feed crop mixtures, seed mixes and differing soil coverages are effectively utilised for an efficient weed and erosion management. If needed, a third crop can also be metered and applied via the on-board GreenDrill 500.
The double seed tank with its two metering units is very simply handled on the Cirrus-CC. So, for example, calibration of the two metering units is done very easily with the aid of the optional TwinTerminal 3.0 located on the machine. This takes away the need to have to permanently climb up and down from the tractor as both metering units can be calibrated directly on the machine. Also the application rates and the rotation speeds of the two metering units are very clearly displayed on the ISOBUS terminal. A change in seed rate of either metering units is possible by the driver during operation from the tractor cab.
