my tractor has 20hrs and started leaking at the fittings like crazy, i found the nut on top and bottom of plate were loose and the fitting on top of nut above plate was also loose. this one seems like it might have a o-ring between it and nut below, because i can see a faint black line under it. 3 tightened really good, the other seemed like it tried to keep turning after i snugged it down. no leaks right now. Is this normal?
