-
Pulled fully rearward-Extend position
No. 1 SCV is normally connected to the loader boom cylinder and raises when the lever is pulled rearward.
-
Spring centered-Off and locked position
SCVs are locked to hold the boom and bucket in position.
-
Pushed slightly forward-Retract position
Boom cylinder is lowered, valve can be metered to control rate of lowering.
-
Pushed fully forward-Float position
SCV connects both cylinder ports to the return circuit. Loader boom can move freely to follow ground contour. Lever must be manually returned to neutral.

Inward and outward direction (B) has the following position:
-
Pushed outward-Extend position
No. 2 SCV is normally connected to the bucket cylinder and dumps when the lever is moved to the right.
-
Pushed fully outward-Regenerative position
