Hello MDD,

It usually means that there are 3 separate valves... giving you the ability to
have three separate functions.

An example would be... valve for loader arms, valve for bucket, and a valve
for another function... say, a log grapple... or some other attachment.

There would (should) be three controls in the cab... one for each function.

If I'm in need of correction... please do so... I could be......

Thats what I have always went with.

hmmm.. ok. Found some other good deals on the net and a few said that as an option. I was trying to rule 3 spool out as another description for the 3 fingertip sticks instead of a joystick.

It usually means auxiliary hydraulics. One spool is boom, one bucket, and the third for four in one bucket or some other attachment.
