While popular in horticultural operations for harvesting over the past few decades, many growers have switched from gantry layouts in favour of very large self-propelled machines.
German company Kalverkamp is now looking to give the gantry a new lease of life. It recently took out the only gold medal for innovation offered by the Agritechnica Event.
Featuring autonomous operation, an electrical power source and modular construction – allowing operating widths from 6 to 24 metres – the machine can take care of tasks including cultivating, drilling, spraying and harvesting.
Called Nexat (next generation agricultural technology), a 270-degree rotating cab allows the unit to be driven manually between jobs and a prime position for process monitoring in the paddock.
While hydrogen power is planned for the future, currently the vehicle is fitted with twin 545hp (400kW) diesel engines that power electrical generators. This in turn powers the four rubber tracks, which rotate through 90 degrees for transport.
With the NexCo combine harvester module fitted, the vehicle is said to offer outputs of 130- 200 tonnes/hr, using a 5.8m-long dual axial rotor mounted transversely to the direction of travel, and a cutting width of 14 metres.
A 32 cubic metre grain tank is said to be large enough for most paddocks, with a 600 litre/ second unloading speed taking around one minute to empty at the headland.
Several manufacturers are involved in the development of implements for the system, such as Swedish company Väderstad, alongside German sprayer builder Damman.
