Backhoe quick disconnect on bx25 backhoe

[bxn]

While digging a 60' trench for some drain tile I noticed at about 50' (as the rain started fall) everything stopped dead with the a little hydro fluid smell in the air. I looked down and saw the quick disconnect had come apart.

I shut down reconnected - everything was aok except the rain soaked me out for a while.

Looking back at this: I think if it wasn't coupled correctly it would have blown off before that.

My theory is that coupler was banging against the hoe and allowed it to release at just the moment where the line pressure was low and that probably a lower pressure return line.

At the time I was pushing it a bit to finish before the rain rolled in and was bouncing the hoe a bit on the subframe.

Anyone else experienced this ?

Do you tie your line back or wrap it so the coupler won't contact anything?

Thanks

Are you referring to the power byd short hose ? I can understand why it might have happened, but cant say it ever came apart on me. For 4 years so far, I havent had the couplers come apart yet- knock on wood.

A simple rag tied on the fitting in a simple knot is a simple way to cushion the fittings from banging on things. I don't tie one on my bota but I have tied one on the homemade woodsplitter.
I have one on the oil filter and one on a cracking hose. The rag is only there for safety. When the oil filter became plugged and blew, it squirted oil all over me. Boy was I pissed being soaked in oil. I wished I had a rag on it to deflect some of that oil the first time.

Thanks for the reply. I will try that.

It says in the manual that that is the inlet hose that came off.
Its the one where the coupler is right below your feet.

In the end I had the trench filled with tile before our visitors needed to walk
over it.
