I recently rearranged the 1/4" auxiliary PTO fitting setup on the PT and all attachments. From the factory, the fittings on the tractor are both male, and the fittings on the attachment hoses are both female. They all needed dust caps to keep them clean, but keeping the dust caps clean enough to use was a pain.
I decided to copy the setup that PT uses on the main PTO. I bought some extra male fittings and swapped around so that everything has one male and one female.
The hoses to the quick-attach cylinder are just long enough to plug together when disconnected. All of the attachment hoses have plenty of length to plug together for storage.
The two big advantages I've found so far are: No more dirty dust caps, and I don't have to remember which hose hooks up where in order for the controls to work the same way each time.
The one negative so far is that temperature increases can cause enough pressure to build up that it can be difficult to disconnect the hoses. I've had to use a small hammer and punch to tap the sleeve back to release it. At worst, I might occasionally have to unscrew a fitting from a hose.
