Krone launches next generation forage harvester
KRONE has launched the next generation of its Big X forage harvester with three models offering more capacity and improved fuel efficiency.
The most significant development is a switch from the two-engine arrangement adopted in existing models to a single V12 MAN engine in the Big X 850 and 1100 machines and a smaller V8 MAN engine for the new 700 harvester.
The original Big X 500 with its tried and tested technology and 6-cylinder inline engine is still available.
The new engine features an output management system allowing the operator to switch between road and fieldwork, thus maximizing the efficiency of the engine for the job in hand. To achieve this MAN developed the engine with two power curves – Eco Power and X-Power – so on the Big X V12 1100 the Eco setting pushes out 638hp while on X-Power it is an 1034hp.
In road transport, the engine output allows the machine to travel at 40km/h using the lowest possible fuel consumption rate.
Another highlight is the speed control system on the hydraulic-drive cooling fan, which is temperature controlled and brings further economy enhancements.
The Agritechnica 2009 award-winning VariStream crop flow system remains as a standard specification on Krone forage harvesters with six pre-compression rollers and a large 660mm and 800mm diameter chopping cylinder. The spring-loaded base beneath the chopping cylinder and behind the crop accelerator helps to minimise blockages even when the flow of crop is not uniform.
Users can choose between three different models of chopping cylinders with 20, 28 or 40 knives. The Biogas cylinder will reduce fuel consumption by up to 16%/tonne of harvested crop when producing short chops, while boosting throughput by up to 25% at the same time.
A new cab design offers more space and better visibility for the operator. Higher build quality and improved suspension has reduced noise levels, while the climate control system and a mobile cool box bring further enhance operator comfort.
A unique Krone developed joystick is also better for harvesting. A mode selector button in the armrest switches engine power requirement from Eco Power to X-Power.
The price for the new Big X forage harvester is likely to cost up to €20,000 more than existing models.
