eMax 25 HST Unknown Valve

I noticed a valve under the HST pedals. The owners manual has nothing about it. The nut rotates 90 degrees, stop to stop.

What is it?

I’m not an emax guy but it should be fairly easy to track the hoses. I assume it’s to the loader based on the picture. Does it have a BH or something else in the rear? Does your loader valve use cables or is it right at the joystick?

That is just a hydraulic block that provides Pressure, Power Beyond and Tank lines to the tractors that are fitted with a loader.

For the non loader tractors, the spool is flipped to the left and therefore closing the circuit so it will power the remotes and 3 pt hitch. The top hoses are removed and the block is capped with a plug instead.

Possibly speed descent control for your 3 point?
