Abstract
An agricultural working machine has intake conveyor mechanisms, a hydraulic circuit via which the intake conveyor mechanisms are hydraulically driven and including at least one hydraulic motor which drives the intake conveyor mechanisms, at least one switching valve system for interrupting or releasing a flow of hydraulic oil being assigned to the at least one hydraulic motor, the switching valve system being configured for interrupting or releasing the flow of hydraulic oil to the hydraulic motor as a function of a signal from a foreign-object position detection device, the switching valve system including at least one braking function for the at least one hydraulic motor, and a section of the hydraulic circuit which realizes the at least one braking function is essentially free of elasticities.
