John Deere straight 640 skidder. the back rear end is completely full of oil causing it to leak oil past the gasket on the center housing, like it is pressurized, cause, ???????
Can't help you on your question, but a change in title of the post would probably get more views.
If u have internal bakes on your rear axle your bakes could be leaking into the dive over filling it with oil and causing it to blow the seals
