Chock the lever down, and drive off while it’s lowering. Not the best idea on uneven/sloping ground, though. Or if you need to go through a doorway
Hmm. Even that doesn't speed things that much. I spend a bit of time waiting at the field gate after emptying these days watching it creep down! It rises quickly! Think it's an 8 ton trailer.Chock the lever down, and drive off while it’s lowering. Not the best idea on uneven/sloping ground, though. Or if you need to go through a doorway

There could be a restricting orifice in the fitting at the base of the cylinder.
They put them in there in case of a hose blowout.
Need to remove the fitting to see it.
Interesting. I wonder if it does have this and it's partially blocked? It's got two rams. So would it likely have one in each?
It's a 2 stage ram setup on each side. I stupidly gave it a tug the other day (as if I could speed it up) and it seemed to drop the smaller inner ram and push the larger outer up. It didn't speed anything up though!

Do you have another spool you can test it on? Or flip it onto the other connector on the same spool? It might be something stupid that the lever you use is stiff or gets stuck so is not fully opening the spool.
When I pinch our neighbours tractor to empty the muck trailer at the flower people down the road you can plug the trailer into any of the spools as long as you work out which lever and which direction to push it in.
I only have two connectors. I assume one pumps and ones a return but might be wrong?

It'll be bidirectional (double acting) I'd have thought. Most I've seen are, does the lever go both ways from neutral? L
Basically in neutral / default then both ports are blocked off and pressure drains back to the tank. When you move it one way then pressure goes to A and B drains to tank, move the other way and pressure to B and A drains to tank.
If you only have a single acting ram on it then move the lever one way and pressure feeds the cylinder to raise the trailer. Let go of the lever and it stays up as it traps fluid in the ram. Move it the other way and it let's the fluid drain back to the tank being forced down by gravity assistance.

That describes mine. I will try it the other way round when I next connect it up and see what happens.
