This allows emission-free electric drive in closed buildings, and a diesel engine powers the hydraulics and an electricity generator outdoors.
It is one of the new ideas that will emerge at the Agritechnica show in Hanover, Germany, in mid-November. The event has become one of the most important for presenting new farm machinery and equipment, and exhibitors will present nearly 400 innovations.
Also on show at Agritechnica will be a new concept for a hydraulic engine brake, for improved safety in transport operations with trailers.
To minimise accidents on mounting and dismounting from the vehicle and on hitching implements, the tractor can be shunted backward and forward by push button from outside the cab in order to mount and hitch implements.
“This simple solution, presented for the first time, will not be restricted to just one tractor series in future,” says Prof Dr Karlheinz Köller of the University of Hohenheim.
Gold medals for innovations will be awarded at Agritechnica for products showing new functions or which can essentially improve known processes.
Experts from science, research and consultancy, plus farmers, will look for practical application, advantages for farm and labour management, environmental and energy improvement, facilitating work and safety at work.
Silver Medals will be awarded for essential product improvements.
These innovations are part of Industry 4.0, says Prof Köller.
“When mechanical engineering, electrical engineering and information technology join forces with the goal of steering development and production via the internet, we speak of Industry 4.0, the fourth industrial revolution after mechanisation with hydro and steam power, mass production with the help of electric power, and the digital industrial revolution. This development in industry can also be observed by analogy in agricultural production.”
Pointing to some of the other interesting innovations which will be seen at Hanover, Prof Köller said a novel system for tramline control will be on show for the first time.
Creating tramlines with pneumatic drilling machines is frequently connected with complicated re-setting work when changing tramline rhythms and with different track widths. The new system on show will have individually controllable distribution head outlets, which offers unique flexibility and exceptional comfort in creating tramlines with constant exact seed quantities in the tramline area. Track gauges, track widths and tramline rhythms can be selected simply at the operator terminal. The individually selectable half-width shut-off (left or right) allows the start of drilling from both sides, while ‘section control’ permits exact drilling on wedge-shaped fields.
At Agritechnica, a new precision dosing unit suitable for planting maize will achieve a seed rate of 240 grains/m² with a frequency of up to 120Hz (cycles per second) at 12km/h, with a row spacing of 15cm.
This can be added to an existing pneumatic drilling machine.
New disc fertiliser spreaders on show at Hanover will use microwave sensors for automatic adjustment of the spreader.
An arm provided with microwaves swivelling about the distribution disc of the spreader identifies the spread fan and sets the spreading pattern automatically to the desired working width.
The spreading pattern is permanently monitored during spreading, and the fertiliser delivery point is automatically readjusted.
This allows higher precision by comparison with conventional setting practices, without requiring a spreading test on the field.
