Automation technology has found its way into modern agriculture. The operating and control devices of Graf-Syteco ensure efficient and resource savings in tractors, harvesters as well as mobile milling and mixing equipment. Operation of products in agricultural machinery must be ergonomically easy to use. Using a single operating device to control all implements from the cabin of the tractor, is an example of this efficiency. Remote maintenance and remote access to mobile agricultural equipment is possible with the Graf-Syteco system including operating information, job data and current machine states.
