An NH3 applicator implement is equipped with a hitch arrangement for automatically effecting a connection with a tongue of an NH3 nurse tank wagon. A quick-connect coupler assembly is provided for connecting the transfer hose of the nurse tank wagon to the supply hose of the implement. The quick-connect coupler assembly includes a first coupler section mounted to the applicator implement for powered, guided movement into engagement with a second coupler section mounted to the tongue of the nurse tank wagon. An electro-hydraulic control system including relay logic is used to first lock the fully coupled coupler sections together and then to engage the flow of NH3 by remote actuation of a main on/off valve located at the nurse tank.
