Loader Weak curl

[ASEmaster]

My friend has a relatively new M5 091 with an LA1854 loader.
The curl function is super weak compared to my Kioti DK45, and any other tractor I've ever run.
He says he's complained to the dealer, and they just shine him on telling him that's how they are. He says he went and tried other new even larger Kubota tractors at the dealer and they also feel weak.
I think their excuse is that they are detuned to get them through warranty or some such garbage.
Is this just how it is or is there a way to dial this thing up to where it should be?

This is how I would troubleshoot this.

1. Get the service manual's perspective on the rated PSI for that section of the loader or system itself.
2. Get a gauge that is to be of known working order and plumb it into the system.
3. Compare what the reading to what is in the service manual. Also note what it is before making any adjustments. Also post on here what the reading is.

Great idea. I do have a gauge. Does anybody know what the psi specification is on the loader system pressure?

Did you ever chase this down and figure out what was causing the week 1854 loader curl?

I don't know what "weak" means. Does that mean it won't curl with the bucket full or is it just slow? The specs show 2.2 seconds to dump and 2.4 seconds to rollback. That is lightening fast compared to mine.

Many valves have a relief. Some are adjustable. Or there may be a restrictor on the curl line. Or the owner is trying to raise and curl at the same time.

That's the problem with some of these Zombie threads. No feedback.
