A system and method for interrupting a Global Navigation Satellite System (GNSS)-based automatic steering mode of a hydraulic steering system on a vehicle. When a steering wheel is manually turned by an operator, pressurized hydraulic fluid from a steering directional control valve activates an interrupter having an interrupter valve. The interrupter valve blocks pressurized fluid flow to the automatic steering system, thus overriding automatic steering and giving the operator full manual steering control via the steering wheel. The hydraulic interrupt system is mechanical with no electronic elements.

Hydraulic interrupter safety system and method

A global navigation satellite system (GNSS) based control system is provided for positioning a working component relative to a work surface, such as an agricultural spray boom over a crop field. Inertial measurement unit (IMU) sensors, such as accelerometers and gyroscopes, are mounted on the working component and provide positioning signals to a control processor. A method of positioning a working component relative to a work surface using GNSS-based positioning signals is also disclosed. Further disclosed is a work order management system and method, which can be configured for controlling the operation of multiple vehicles, such as agricultural sprayers each equipped with GNSS-based spray boom height control subsystems. The sprayers can be remotely located from each other on multiple crop fields, and can utilize GNSS-based, field-specific terrain models for controlling their spraying operations.
