A safety system is provided for an anhydrous ammonia nurse tank ( 4 ) pulled by a tractor ( 1 ) with a tool bar applicator ( 2 ). The system includes a safety valve ( 10 ), and a breakaway coupling or connector ( 12 ) along a flexible hose ( 11 ) from the nurse tank to the applicator. The safety shutdown valve ( 10 ) closes in response to a break in the electrical connector in the event of a pull away or manual activation of a safety switch. |
