With an extremely carefully and very dedicated approach, power transmission may, but not obligatory, present a serious technical, environmental or econometric problem. In agricultural engineering, this process is unfortunately often further complicated. Therefore, energy transfer in this particularly sensitive area must be performed with special care, and energy-specific technical solutions must be applied in each isolated case. These solutions must be specially harmonized with the dynamic energy needs of the system, and should provide energy transfer that is technically, technologically, economically and ecologically harmonized with the practically unpredictable dynamic needs of hydraulic elements and systems in agricultural engineering. However, the use of hydraulic drive, or at least its participation in power transmission, has become an almost inevitable practice today. This is especially important if it is also electronically controlled, because with a number of additional advantages including fluid line flexibility, energy transfer from arbitrary types of primary sources and energy converters, all the way to the appropriate control units or consumers can be achieved successfully, efficiently and accurately.
