Too many Kubotas

I've had that happen with the couplers for a grapple, once.Well, I have read that releasing the pressure, if needed, on the flat-faced couplers is very difficult. I know that with the poppet type you can bang them against something hard and get a release out of those.
So instead of pushing the male onto a flat surface, I had to use something that protruded enough to release the pressure on the flat faced version. Specifically, one of the serrations on the side of the rock bucket.
As often as I switch hydraulic hoses around, having it happen once in 10+ years is something I can live with. And it was likely self inflicted, having clamped the grapple closed in cold weather, then going to reinstall it when it was warm.
Anyway, to me it'd be great not to have fluid drip from every female connector on the back of the tractor (six) and making a mess whenever I disconnect the hoses. The flat faced ones sure seem more substantial, and appears to be used on everything except our tractors.
