Backhoe Removal/install BOBO

[TalonDancer]

I removed the BH90 today to do a little box blading. It's been nearly 2 months since the last time I took it off. Boy does that GL3240 look naked without the hoe

Everything went well until I went to hook up the hydraulics while re-installing the hoe. You guessed it I had left the hoe up in the air supported by the stabilizers to "save time". After all it was only going to be off for a hour or two. Well the hoe was fully pressurized. Those little black buttons would not budge

So I spent the next hour building a support for the hoe --
* finding enough blocks of wood (of the right size/strength),
* lifting the hoe carefully with the FEL to take the weight off the stabilizers
* manually lowering (extending) the stabilizers to release the pressure
* supporting the hoe on a stack of wood on loose soil
--- so that could turn the tractor around and hook it up with no weight on the stabilizers.

Well it just barely released enough pressure. But I did get the hoe hooked up and back on the tractor.

BTW - I "saved" about 2 minutes by leaving the hoe up, and lost an hour - DUH. Maybe next time I'll re-read the instructions on that big label right on the side of the hoe BEFORE I take it off

Bummer.

I haven't tried it yet, but my Bradco has a small pressure relief valve that I believe is intended to deal with exactly this situation. It's nothing more than a small needle valve that tee's off the main hydraulic line with a drain tube down to the ground. I don't see why you couldn't retrofit something similar to the main hydraulic line on your BH90 to accomplish the same thing.

I leave my backhoe up on the stablizers all the time. Yes, it settles some. All you need to do is place a rag over the male QD and tap the end with a wrench or hammer to relieve the pressure and your good to go.

Now you tell me

I thought of doing what you describe but had no idea how much fluid would be expelled (i.e. potential mess on the ground) or how hard to hit the little black button on the male QD (i.e. potential damage). FWIW I did try pressing it against the frame pretty hard and it didn't budge.

Does it expell much fluid?

I may try to retrofit a pressure relief valve if I can't remember to let the hoe all the way down in the future
