I removed my LandPride SGC 054 grapple from my tractor, which has new Summit flat-faced couplers installed on the hoses. As soon as I disconnected the couplings from the 3rd function valve the grapple started to close and the male coupler started spraying oil out until I put the male and female together. Is this normal or is the male coupling defective? I remember reading that the grapple is supposed to be stored in the open position so the cylinders are closed and that is the reason for my removing it in the open position.
