Kenneth,
Forgot to mention a trick to your problem with getting the hydraulics connected. I run everything with skid steer flat face couplers because they are heavy duty and I it gives flexibility between machines. However, they are very difficult to connect, especially when it gets hot outside. But there is a trick the makes them connect with ease.
Step 1- anytime you go to connect or disconnect your 3rd function attachment set it down and shut your tractor off. Turn your key on but don’t start it. Since the 3rd function solenoid is electric this will allow the valve to function without hydro pressure. Cycle your open and close buttons several times each and this will take any pressure out of the system.
Step 2- if you are using flat face couplers like i do, they can still build up pressure especially if out in the sun or when its hot. Best thing you can do is as soon as you disconnect them from your tractor, connect the 2 hoses into each other. This also keeps your ends clean btw.. Since I’ve been doing these 2 steps I’ve never since had an issue with a difficult connector.
One other note, always fully close your grapple before disconnecting because the weight of the that lid will make reconnecting that hose next to impossible. Made that mistake once and ended up having to have my wife hold the button on the 3rd function open while i fought the hose to connect. Huge pain.
But if you shut off your machine, then turn that key back on without starting and cycle that valve several times, that will make all the difference in the world connecting those hoses.
Take care, and God bless. Happy Resurrection Day!
