Intake conveyor mechanism control for an agricultural working machine

An agricultural working machine, comprising intake conveyor mechanisms;

• a hydraulic circuit via which said intake conveyor mechanisms are hydraulically driven and including at least one hydraulic motor which drives said intake conveyor mechanisms;
• at least one switching valve system for interrupting or releasing a flow of hydraulic oil being assigned to said at least one hydraulic motor, said switching valve system being configured for interrupting or releasing the flow of hydraulic oil to said hydraulic motor as a function of a signal from a foreign-object position detection device, said switching valve system including at least one braking function for said at least one hydraulic motor, and a section of said hydraulic circuit which realizes said at least one braking function is essentially free of elasticities and wherein said switching valve system is configured as a proportional servo valve, in which motion of valve pistons is controllable via triggering of at least two control cylinders.
