Operation control system for automotive working vehicles

摘要

An operation control system of an automotive working vehicle has a self-resetting switch as a switch for stationary operation and a self-holding circuit. The self-holding circuit is set by operating the self-resetting switch to a predetermined set state when the following predetermined conditions are satisfied: detection of a driver's seat being unoccupied, detection of a transmission being in neutral, and detection of a PTO shaft for stationary operation being selected. In the predetermined set state of the self-holding circuit, the engine of the automotive working vehicle can operate even when a PTO clutch is engaged, provided that the above predetermined conditions are satisfied. In another form of the invention, the predetermined conditions further include detection of a parking brake being locked.
