Kubota B6200 4WD front axle fill plug stuck!

[greenie-reddy]

B6200 4WD gear driven tractor. Built about 1988, has only 300 hours of use. NTL, while performing complete fluid change, ran into snag on the left front wheel sump. Someone before my time either over-tightened or cross-threaded the fill plug. It’s a little square headed plug about 10mm. I have used about as much force as I think it can stand and it won’t budge. Perhaps heat is next. I was wondering, is there any other way to get gear oil into the pumpkin without using this plug? It takes all of about 0.15 quart, but I don’t want to drain the thing until/unless I have some way to refill it. Any ideas? Thanks.

Can you get another plug? If so, twist it harder......after penetrating oil of course

....and maybe rap it a few times with a hammer to loosen it.
