I have a Royal King 37 hp tractor, with the backhoe attachment. If I don't bleed down the hydraulic system, tractor shut down, cycle all controls in tractor and hoe before I disconnect the hoe from the tractor, then I cannot get the quick disconnects reconnected when I setting up to use the hoe again. In that case, I then need to take cover off of controls and open the system to relieve the pressure. PITA!
my question is there something I can put in line that I can relieve the pressure w/o taking it all apart?

Have same issue with a 2305 Deere loader attachment, anything functional would be ridiculously expensive.

Dave, I'm sure you are right, but it sure would be nice to have a manual pressure relief that could be installed in line with the two hoses going to the hoe.

Thanks Hud! Dave was right, not cheap!

could you put a 3000# valve with a couple 1/4 inch hoses between the supply and return lines as a JUMPER... open the valve and relieve the pressure back to suction side ?
Like them all, but love the "B"s.

Steve, I don't think that would solve the problem completely. It would equalize the pressure between the supply and return on the hoe, but not necessarily between the hoe and the tractor. Most often it is only one line that is pressurized, but on a couple of occasions it is both. I know I am prone to 'forgetfulness', but I am pretty sure I am bleeding them at least most of time, yet, when it comes time to reconnect, I find one or both lines w/some pressure prohibiting me from making the connection. I suspect that as the hoe settles, the weight of the hoe on one or more of the cylinders is causing the issue. I need to discover a way to support the hoe better, I think. I was hoping for a relatively inexpensive solution of an inline pressure relief, but what I have seen so far is beyond my budget.

Hmm, so cheap and dirty? Heavy on the dirty? Not much is cheap these days. How about just before the hose tip, put in a tee and a little ball valve on the branch of the tee.   Carry a coffee can with you when you hook up and crack the valve into the coffee can. If you can keep it clean dump it into your oil supply. If not pour it on moving parts. Not elegant but beats slamming the hose tip onto the drawbar and spraying oil everywhere.

I tried the slamming trick, but not enough man in me to get it to work!3000 psi system

Where are you storing the backhoe?  If it gets full sun, the fluid can heat up and lock the fittings up, don't ask me how I know...Wink

Come back in the early AM or on a cloudy day, and sometimes the locked fittings work like a charm...
