The OP's problem sounds like a procedural problem.
If you relieve the pressure in the tractor and implement before disconnecting then the issue is your implement storage.
FYI Your tractor engine has to be off to relieve line pressure. If your valves are electric actuated then the engine has to be off but the electrical on to actuate the valves. You should hear the valves actuate and see the lines relax when pressure is relieved.
If you leave implements outside and in the sun you will have problems with pressure build up in the implement. You will need to crack a fitting to relieve pressure built up in the implement.
I keep my attachments indoors and out of the sun and rarely have issues. If I detach in the morning and leave the attachment out in the sun all day I will have to crack a fitting.
