Diverter on JD H260 - slow curl

[KY Gun Geek]

Working through installing a diverter to run a grapple lid on a JD 5093e with an H260 loader. One is activator switches being eaten - here's a link to a separate thread about that:

The other issue is that that bucket curl seems to be be much slower.

I originally installed the diverter in the lift circuit, and I didn't notice any function problems, but this operation seems clumsy to me (I can't walk and chew gum), so I reconfigured to put valve in curl circuit. Now curl seems slow.

I was previously able to shake the joy stick to shake the bucket - very good for shaking packed in sticks etc out of the grapple. Can't shake any more, and curl is irritatingly slow. I don't shake the stick much, seems hard on the system to do that but the curl speed is a problem. Seems to generate plenty of force (though I haven't really tested it with work).

I'm thinking that the diverter valve doesn't have the flow rate. It is rated at 13.2 GPM. Tractor pump rated at 15.9. This is a deere tractor, and my understanding is that there is no regen feature like there is on the kubotas. Though to be honest, the symptoms sound very close - slow curl and I think the system loads when I float the bucket (very similar to what I've read here about the kubotas).

What gives?

Thanks in advance...

So I think this one took care of itself.

The answer is F-A-R-T

We were working through some stuff on the other issue with the switch and heard some groaning in the diverter, then the bucket started moving. Pretty sure we just had some air in the cylinders (from plumbing into the curl circuit) and I hadn't worked it out.
