4 in 1 bucket problem

[LabLuvR]

I took the loader off my Kubota MX 5400 like I have done several times. Today when I put the loader back on everything worked fine, except the 4 in bucket would not open. I double checked my connections and everything seems good. What am I missing? Thank!

Did you try the control in both directions? Possibility reversed?
I would also remove and reconnect the 4 in 1 hoses if you just did a visual check.
