I solved my problem of my 2N "with heavy load on rear boom, locked up, unable to lower until cyclinder leaked down".
I replaced the NEW SAFETY VALVE, with an old one. The new one has "screw driver, preset on outer end", while the old one has a "cotter pin" to retain the spring, on outer end.
Wished I had pressure tested the new one (and old)
My theory is that the new safety valve exceeded the pressure specification and therefore the old control lever spring
(Between cylinder and forks), could not over come the spring specifications. This problem only showed up if I tried to pull fence post or electrical grounding rod or 500# 0n rear boom.
Lesson learned: Pressure test, before replacing safety valve.
