Default loader bucket won't lower

I just bought a used B7510 HST with a Woods joystick bucket. The bucket will go up and rotate up and down but the bucket will not lower. Ideas please?

Lower your 3 point hitch a little and try that. If the 3 point is too high then it will mess with the loader, took me months to figure that out. Kubota must not have set the upper stop right on my tractor.

Check that the return hydraulic coupling is correctly attached. (Be careful - it may be under pressure.) I think in the 'float' position it should at least lower by gravity alone if the couplings are attached correctly.

'Float' is when you push the joystick ALL the way up. It releases all pressure from the hoses. (Assuming you have float). If it doesn't drop in the float position then the coupling may not be correctly attached.

Could be faulty quick release coupling but also hydraulic ram. Eliminate problems starting from lifting cylinder. Loosen up hoses on cylinder to see if oil comes out and if bucket drops. Swop couplings if necessary.
If those 2 ok then you might have a faulty control valve block.
