In response to longer chop length requirements in maize, Claas has further developed its existing Multi Crop Cracker (MCC) concept, for its range of Jaguar forage harvesters, with two new models; the MCC Max and MCC Shredlage.
Both corn crackers feature specially developed roller profiles which allow intensive conditioning of silage with medium to long chop lengths of up to 30mm, says the manufacturer.
The new corn cracker systems integrate with the existing Claas MCC concept and allow various roller options to be changed depending on the desired conditioning level. This includes the current MCC Classic standard cracker system with saw tooth profile, suitable for short cut silage from 3.5-12mm, says the manufacturer.
For longer chop maize, the new MCC Max can cope with lengths from 7-20mm, says Claas. Its rollers also feature a saw tooth profile, but split up into 30 segments each.
It is the positioning and geometry of these segments which allows the chopped maize to be not only processed using friction, but also by cutting and shearing forces.
The result is more intensive conditioning of the kernels as well as shredding of the stalk, says the manufacturer.
For processing chopped maize material from 26-30mm, Claas has turned to American company Shredlage L.L.C.
After acquiring a licence for its technology, Claas is now able to offer the MCC Shredlage crop processor.
Featuring a saw tooth profile with an additional counter-rotating spiral groove, this allows the MCC Shredlage to break down the cob pieces and crush the kernels to break them open completely, it says. Furthermore, the stalk material is shredded in the longitudinal direction and the bark is peeled off by the roller’s profile.
In future, Claas will manufacture Shredlage rollers itself under licence. Like the MCC Max, the MCC Shredlage will be available as an ex-factory option or for retrofitting from 2016 for the Jaguar 870, and the 950 to 980 models.
