A lock-out system can monitor the position of an implement and lock-out the implement control(s) when the implement is within a threshold distance to parts of the machine. The lock-out system can generate an implement lock-out to slow, stop, or reduce the force of a hydraulic valve(s) controlling the implement. The lock-out system can use inputs such as electronic fence blade position system data, articulation angles, wheel lean angles, steering angles, ripper positions, mode selection or similar data to determine to generate the implement lock-out. The lock-out system can generate the implement lock-out by a flow supply shutoff to the implement while maintaining pressure to the steering valve. The lock-out system can send visual or audible notifications to alert the operator of the implement's proximity to the machine or of an implement lock-out.
