[oddduck49307]

Ive got a massy tractor that ha what appeares to be s40 couplers but trying to unhook the front bucket lines i cant figure out how to unhook the female coupler is mounted on th bulkhead and the collars rotate the whole thing so how do i get them apart

Either push or pull the sleeve on the QD and you should be able to disconnect.

Tried that but the collar appears to be one piece but bigger channelox and a hammer may help

They are all one piece sleeve.

Try pushing in with the hose and then pull the sleeve back and then pull the
QD and hose assembly.

Did you relieve the system pressure before trying to uncouple the couplers?
