Detent vs float valves

[Jim Meade]

I have 3 '55 series tractors, each with 3 external hydraulic valves. Each has two detent and 1 float valve.
I'm going to take apart, clean and if repair the valves.
My question is when do you like detent versus float? I have read the operator's manual but that's not a big help.
One 1855 with a loader is going to get a separate Gresen valve for the loader plumbed direct.
I want to put each valve on the lever I prefer for it's best use.

Make sure you use a Gresen V-20 CLOSED CENTER valve and not an open center valve with a closed center conversion plug. Needless to say you want a float valve for your loader. Do you understand the purpose and how a float valve works. I probably have some Gresen literature left I can snail mail you.

Let me clarify that I will plumb the loader entirely separate, and know that I need a closed center setup, not a conversion.
On the external valves, that will not be used for the loader, what would I normally want a float valve for? I'm thinking I'll put the front two external valve levers as detents and the back lever on the float. Normally, I'd run the front two levers as a pair if I were running two cylinders on some machine, like a planter. Since I'm not going to plumb the loader through an external valve, I'm not sure what I'll use the float feature for. I'm looking for hints so I'll know where to put it on the stack. Middle or right.

Make sure you use a difusser on that loader return. Now do you have any equipment that would need 3 hydraulic functions? Ten years ago 2 remotes were find now we have 2 tractors with 3 and we need them. A closed center valve (your Gresen) will have an antidrift cartridge which is good.
