Abstract

See full text

A hydraulic system for a self-propelled agricultural working machine includes a variable displacement pump driven by an internal combustion engine (1) and supplies a plurality of hydraulic circuits, a swept volume of which is changeable via an adjustment mechanism, and supplies pressure medium via at least one pressure line to a hydraulic motor. The hydraulic motor drives a radiator fan. An output of the radiator fan is reduced, at least temporarily, in the event of a drop in pressure for which the variable displacement pump cannot compensate.
