Loader all of a sudden has no down pressure

I'll go at it again tomorrow, I'll give that a try, thanks for your help, I living and learning here

Ok the mystery is solved, as it turns out their is nothing at all wrong with the tractor. The tractor has a backhoe on it on the lower 3 point arms. While pushing back brush with the loader I pushed the lever engage the 3 point hitch in the open position. With it in the open position is siphoned off enough hydraulic pressure to cancel the down pressure on the loader. Overlooked the obvious and assumed it had to be a flow function.

I have a b7610, was out working with is and it was working fine and then the loader wouldn't drop with pressure. When I push the joystick the loader doesn't mover. It will lift fine dump and curl fine but will not drop under hydraulic pressure. It will only drop if I push it into float and then gravity will let the loader drop. When it is on the ground and I tip the bucket it will lift the tractor. Any thoughts on this. The quick disconnects appear to be working but 1 was a little sticky.

I’m sorry to open up a 11 year old post but I have the same problem with my B 7800. I have swapped the bucket and the dump hoses to which I only have bucket up even though I try to get it down. In other words, when I move the joystick left and right, the bucket only goes up, no down. When I move the joystick up and down the bucket does tilt forwards and backwards.
I have checked all the QD’s and they are fine, I have disconnected and reconnected then.

Check your 3ph control lever, it might stuck in the up position, not allowing any return line flow out of your FEL control valve.
