I have a Murray 17.5 hp Garden Tractor. I just went to change the oil prior to using it, The plug will not come out for anything. The correct size socket just strips it... This sucks. Would anyone have a solution ?
Thanks
vicegrips?
There is a difference between 6 point and 12 point sockets.
I wouldn't hesitate to put a pipe wrench on it. Plugs are cheap to replace.
be SURE to set the caming action on the vice grips as tight as you can. in the past, I've used a C-clamp to set the vice grips.
I bet you got a cast aluminum engine block with a steel drain plug. if so then there is a really good possibility seizure has occurred. in this case it's not just stuck but rather the two different metals have bonded to one another due to their different temperature coefficients defining how metals expand and contract when repeatedly heated and cooled. under these circumstances it's not uncommon for the female threads in the aluminum engine block to break after sufficient force has been applied and thus remain attached to the steel drain plug. if the threads do break simply drill and re-tap the hole to the next larger size. before installing the new drain plug apply a product called Never Seize, a compound designed to compensate for the two different metal thermal coefficients.
have fun in the shop.
hi Eggs.

run the engine till warm or hot and then try again
I would forget about it and try again next Fall. I haven't changed my oil in 17 years and it works fine.
Anti-seize is also alleged to reduce galvanic corrosion and oxidation of the aluminum. Recalling that the original VW Beetle had problems with various engine studs freezing in the aluminum block, I Googled. That reminded me that there was the same sort of problem with European motorcycles of roughly the same vintage. (Harley didn't care how much their motorcycles weighed. ) Anyway, the search returned up this thread that you might enjoy.
Just don't mix up the tubes of anti-seize and Loctite.

I'm fairly confident that that comes as a shock to very few, here.
Start the engine and heat it up before you try to remove it.
