Two loader functions

[TomIre]

Now that I have a grapple, I'm bothered more by not being able to do two loader functions at the same time. For instance, curl and lift at the same time. My dealer said there is a very narrow "window" on the joystick control where that can be done.
I haven't found it! Have you?

You could replace the valve with a series/parallel type valve. With this type valve the tank port will close allowing the remaining fluid from the first spool to be used in the second. It is limited to flow of course and will operate slower.

A series valve has such a small window to allow for simultaneous operation that it is impractical to utilize.

Before you had a grapple, could you curl and lift at the same time?

I can't lift and curl at the same time either (3725 with BL20 loader). It doesn't matter what's attached to the loader. I think it's the valve. The cable linkage might make it more difficult. I could lift and curl with my old Kubota even though the lever linkage was worn, so I don't think it's me. Most of the time it is not an issue but every once in a while I wish I could make it work.

That's interesting! I didn't know there was such a thing as a series/parallel type valve. Sounds like I need to do some reading.

Just be mindful that it is not perfect and the cylinder with least resistance will move first. Mine works with a 10 GPM pump but it is slow. Higher flow would help a lot.

No, I couldn't. Sorry I wasn't clear. Just didn't seem to need it as much with the bucket. With the grapple it would make a few things easier.

My 4720H with BL20 can curl and lift/lower at the same time. Unfortunately for me I can't seem to find the right spot with the joystick when I actually NEED to do it. When there is a load in the bucket or on the forks it is almost impossible to move smoothly, it jerks and bounces unless I hold the stick near the base and move it VERY slowly and only a tiny bit. It's kind of frustrating.

Good. I was wondering if something changed when the grapple was added.

On my machine I use that function when I have my bucket/forks on because the way my loader geometry is made up, the angle of the bucket/forks changes constantly with lift/lower function. It would be nice to have auto-leveling geometry, but that's a different subject.

So if it operates slower with the series/parallel valve would the next mod be to replace the pump with a higher volume one?
