I have a M7040 with dealer installed 3rd function. I purchased a grapple and it won't plug in. It's connectors are for skid steer and are too big. Would it be best to change the tractor connections or the connections on the grapple? I think that the tractor connectors ar 1/2 fnpt. I may purhase a lane shark later and want to be able to plug it in. Thanks.
