Abstract

Controls for the implement suspension on tractors, in which electrical signals proportional to the pull on the suspension and to its adjustment are generated and are compared with preset desired values, and the implement suspension is readjusted as a function of the deviations determined and, in the ''mixed mode'', the settings of the pull signal and position signal are superposed on one another, are to be capable of being adjusted easily, even under difficult working conditions, without a clear view of the settings previously made and of the effect of a new setting being sacrificed thereby. This is achieved, here, in that, in the ''mixed mode'', a number of predetermined mixture ratios are provided and can be set selectively by the driver.
