JD 6415 hydraulic flow lever

[Shadscale]

When I lift the little plastic stopper to lock the lever into continuous flow it won't flow. If I hold it about half into the lock position it keeps things going. Any suggestions to have the lock position keep fluid flowing, right now I'm having to tie baling twine to hold the lever into position.

Pulling that stop up lets the valve go in float. I know on our 7520 there is a knob on the backmof the tractor u turn that keeps the lever locked
