No pgk' - I use plugs and caps of course when the quick connection valves (QCs) aren't connected, but so much dirt attaches itself around the QCs on the tractor that it's a real clean-up job before I can consider removing the plugs to connect up or, if implement mounted, pull the valves apart to unmount. It's a chore I could do without, after a long day in the fields, even though it doesn't actually take very long.
For when implement mounted and QCs connected, I'm looking to wrap the connections to keep the dirt off so that all I have to do is slip off the "wrap" to reveal nice clean QCs ready for disconnection.
I'm sure I will come up with something (better than an old sock or bit or rag) idc: I just wondered whether anyone else had the same issue and had contrived the perfect solution.
