Abstract Today’s agriculture is facing major changes caused by digitization and automation. This white paper is intended to provide an overview of and summarize current developments and tendencies. The focus is on the use of electric actuators and their influence on the development of future ma- chines. Only the application and development in agriculture is considered. For this purpose, a comparison of hydraulic and electric actuators is first performed, then current applications of linear actuators and control and regulation concepts are dealt with and the necessary power requirement of current tasks is estimated. The trends of the agricultural machinery of tomorrow are outlined based on this. Future developments and require- ments, digitization, communication and the future of linear actuators in agricultural machinery and robots are presented here. It is to be expected that linear electric actuators will further advance the development of agri- cultural machinery in the future and enable new potential for optimization.
