Got tired of having my quick connects on my grapple not pushing onto the third function connectors because the grapple sits in the sun and raises the pressure in the lines. So I fabricated a pressure release tool to make it simple to let the pressure off the hoses. I looked online at Boltonhooks.com and fashioned this one from materials I had on hand. It’s a simplified version and will only fit the male and female connectors I have on the grapple, but that’s ok, as it’s the only fittings I have problems with. Took a half day in my shop, and another couple hours to prime and paint. Work just as it should. I just wrap a rag around the tool and fitting to catch what little fluid come out. Even center drilled the threaded rod to capture the pin on the connector. No more cussing at getting my grapple connected

I like it. Nice fabrication!

I’m low tech in this case though... I just use a wooden dowel and give it a light smack with a hammer...no grapple here though...🙁

Nice job on the fab. I had the same issue, but I just keep a micro quick clamp in my tractor toolbox (fits in the palm of your hand) and use it to gently depress (and hold down) either button on the 3rd function control (key ON, but tractor NOT running) while I plug in the hoses.

Hoses slip right on, since the oil has a path to go to.

One of these:

I have tried the hooking the hoses together method and has worked mostly but this year one had built up enough pressure that I could not disconnect the hoses until I bled off some oil.

Just used mine again the other day. Had taken the grapple off to use the forks, and by the time I got back to putting the grapple on, the sun had moved enough so the grapple wasn’t in the shade. It pressurized the hoses to the point I had to pull out my tool to relieve the pressure.

I usually link the grapple/auger lines together. Sometimes they're quite hard to disconnect, one time it was impossible and I had to loosen the fittings.

Now, I take the male connector and push the ball against the frame to bleed out some of the pressure, and then I connect the lines together.
