B2400 with LA351 f.e.l

[Jonmichael]

Tractor just recently lost down pressure on f.e.l. Seems to be stuck in float? Does anyone have a schematic for a 6p427a valve? Thanks

I can speculate that the detent or detents are sticking on the boom side spool.
You could disassemble that side and check for rust and water issues or replace complete assembly. Should be A which is float by description.
