A system for detecting a connector failure associated with an agricultural apparatus is disclosed. The system comprises a first supply source that is configured to supply a quantity of air at a first pressure into the hydraulic fluid line arranged on the agricultural apparatus. A second supply source is configured to supply a quantity hydraulic fluid to the hydraulic fluid line at a second pressure that is less than the first pressure. A protection device is coupled to the hydraulic fluid line and is configured to inhibit flow of the hydraulic fluid supplied by the second supply source when a pressure differential across an inlet of the protection device exceeds a predetermined threshold.
