Advanced harvesting technology nets two Agritechnica silver medals

 New Holland’s Opti-Speed straw-walker system is claimed to improve productivity by up to 10%

New Holland has been awarded two Agritechnica silver medals for combine harvester innovations. The unique Opti-Speed straw-walker system improves productivity by up to 10% and the Cornrower header perfectly combines in field efficiency with New Holland’s hallmark commitment to sustainable farming practices, says the company.

“New Holland is committed to developing innovations which bring practical benefits to the world’s farmers and contractors,” stated New Holland Agriculture brand president Carlo Lambro. “Furthermore we, together with the world’s farmers, have the great responsibility of maximising sustainable food and energy production. Opti-Speed technology helps reduce losses, which subsequently means more grain is available for food production. The innovative Cornrower header enables farmers to produce both food and fodder from maize crops as well as converting the previously wasted by-product of maize stover into productive energy through biomass.”

The Opti-Speed straw-walker technology, which was recognised with a silver medal, is exclusively available on the CX7000 and CX8000 Elevation range of super conventional combines. The range includes the world’s most powerful straw-walker machine, producing up to 490hp, designed for large-scale farmers and contractors.

The unique Opti-Speed system delivers up to 10% higher productivity by automatically varying the straw-walker speed based on the field’s gradient, explains the company. The operator simply selects from four pre-set crops, and the Opti-Speed system autonomously modifies the straw-walker speed. When driving uphill, the straw-walker speed reduces to decrease the transport speed of the straw over the straw-walkers and when driving downhill, straw-walker speed is increased to prevent blockages. Moreover, in flat fields, this system is particularly beneficial for maize harvesting thanks to slower straw-walker speeds. As such, a productivity gain of as much as 20% can be achieved, it says.

One-pass swathing reduces operating costs and improves bale density

New Holland, through its Clean Energy Leader strategy, is committed to improving farming productivity and sustainability and the silver medal winning Cornrower header is a key element in  this. The fully integrated Cornrower system can be fitted to conventional maize headers, and it produces uniform windrows of finely chopped maize stover. This fine chop can increase bale density by up to 15%, and the bales also benefit from improved combustion and fermentation profiles, perfect for biomass production.

This one-pass system reduces operations’ fuel consumption as well as limiting in field compaction, claims the company. Furthermore, all maize stover is chopped and remains clean and free from dirt and stones. Any lost kernels fall onto the windrow, and as such bales used as fodder have an improved nutritional profile.  This superfine chop system also allows the stover to release moisture more quickly to reduce the time from chopping to baling. Additional usages include as absorbent animal bedding and as a ration supplement which, when mixed with hydrated lime and water can help to reduce the cost of fodder by up to 40% when compared to traditional maize silage.
