I ordered this valve Brand Hydraulics 2 Work Station Kit 3-Position Detent, Tandem Center Spooled with Joystick Handle | Control Valves| Northern Tool + Equipment to add rear remotes on Kubota M6040 tractor. I just noticed that is rated for 6 GPM and the tractor pump is 11 GPM. There is no way I should use this valve, is there?

You do know you are not getting everything in the picture/link.

It appears they are selling you the two spool with joystick.

The work station includes one section with joystick. The picture that is shown is generic. It is not what you are purchasing.

And yes,, you need a valve that will handle the flow on your tractor.

Here is a similar valve for $458. 6 spools.

The tractor flow is 11 GPM. Will a 10GPM valve be ok?

J_J · Aug 21, 2013

Yes.

What kind of valve so you really want?

A two spool joystick valve ?

Thanks JJ, Yes I want a joystick valve to control stump grinder. They have this one in stock now. I will send the other one back. Brand Hydraulics Monoblock Loader Valve, Model# PLV22TSTKAB | Control Valves| Northern Tool + Equipment

I did not know what you wanted the valve for.

Are you sure you want float and regen on a valve that is just going to control two cyl.

Seems to me, that a two spool valve would work better, no float or regen.

lovedgor · Aug 21, 2013

No, it is not necessary. Didn't know it had regen. Float really doesn't matter, does it?

J_J · Aug 21, 2013

Yes, that valve has regen, but only if you push it to the far right, and try not to go into float, or you can disable the float section.

I will have to slightly feather the grinder. I was using it on an old Ford 7600 tractor and had to be real careful not to overdrive it.

What do you mean by over driving the grinder?

How many GPM is the grinder rated for, and how many GPM does your tractor flow?

You can reduce the tractor engine rpm to reduce the tractor GPM's, and save some wear and tear.

Is the grinder wheel driven by a belt and pulley or a hyd motor?
