1969 4020 hydraulic float position

(quoted from post at 11:01:42 04/05/22)
Welcome to YT
There's a hinged plastic stop strip that one needs to raise to allow control lever to move further in slot to engage detent position.

(quoted from post at 12:25:15 04/05/22) On my 1970 4020 with three spool valves, the left one has float position depending on which hole the control rod is on the valve control lever. Hole closer to the pivot point allows float to work, hole further away keeps float from being reached due to shorter valve arm travel.

Not on a 4020. 30 series, yes.

Thanks for correcting my mistake. I should have performed some research before I posted relying on my memory. Below is the instructions in OM for utilizing float position.

I can't help but wonder if the O.P. is looking for a "detent"/locked "ON" position to hold the valve "open" to run his hydraulic motors.

On the other hand, spinning motors need a way to coast to a stop rather than be stopped instantly causing a great mechanical AND hydraulic "shock load".

One would think that would be taken care of by a bypass check valve in the hydraulic circuit on the implement.

Hydraulically-driven centrifugal spray pumps are often set up that way, so an unloaded pump can coast to a stop when the hydraulic valve is returned to neutral.
