thanks. My neighbor used an adjustable wrench to loosen it. When I tried it the wrench kept on slipping off.
I tried to use an adjustable wrench on it before my neighbor did. he is more persistent then me.The "slipping off" part of that I do not understand.. especially if it was already loose.
As posted above, the plug is JD part # RE46687, which is M22 x 1.5 and there is an O-ring that goes on for a seal. The O-ring is part # 51M7045
Sounds like it was tightened too tight and now buggered up..... When replacing, snug is good, any tighter not so good. Good that you are getting the oil and filter changed. Hope it ends well...
