Dealer delivered Friday and spent the weekend doing some light clearing getting used to the controls. Got a bh860 backhoe and 6ft box blade with it. I dropped the bh to use the boxblade sat morning. Few hours later i went back to hook the bh back up and one of the quick connects would not reattach. Was finally able to get the fitting on, but took well over an hour. Is there a way to prevent the hydro pressure from building up?
