Rounded off drain plug

I don't know, since the old one lasted 60 years I might stick with steel. ;)

It doesn't matter if it's brass or steel though brass will never rust to the steel. What's important is the six sided nut on the end. I never use square headed pipe plugs anywhere if I can help it.

There's always light at the end of the tunnel, sometimes it's just farther away than we'd like.

Not tractor related, but applies to this situation:

2002 Toyota Tacoma, started to misfire badly. I narrowed it down to #3 fuel injector. Easy job, right? Well, both the bolts that hold the fuel rail in place snapped off dead even with the threaded holes in the aluminum head.

Galvanic corrosion is a serious pain. Bolt extractors stalled my 19.2v cordless drill, and my corded 3/8" drill. I didn't want to risk snapping the extractor off in the hole I drilled through the leftover bolt, so I kept stepping up bit sizes until all that remained were the bolt threads stuck in the threaded bung.

It was a smooth hole, but I could just barely see the outlines of the threads. Tried a thread chaser but it wouldn't grab, tried a tap, it grabbed and worked it back and forth until all remnants of the bolt were removed. Followed with the chaser, some new SS bolts with a liberal amount of anti-seize. Then I had to repeat the process for the rear bolt!

It was a 25 minute job that turned into a 4 hour job.

Sometimes it's easier/cheaper to simply take it someplace which has the proper tools/experience for the job, as the OP has decided to do.
Hopefully they will get it out with no further complications.

Take it a shop. It should take them just a few minutes to get a pipe wrench on and remove it.

Either you're using too big of a wrench, the wrench is junk or you’re not good at using one. That plug would come out with a pipe wrench. There's several other alternative options but that bar and lack of a welder limit them.

Another vote for a small pipe wrench and maybe a short length of pipe for a cheater bar. You’d be amazed how much grip a decent pipe wrench will have on a plug like this.

Go ahead and drive it to the shop for drain plug removal since you have tried all the suggestions with no luck. Remember to take along your new oil and filter so you can fill the crankcase and ready it for its trip home. Have the shop weld on a new nut to the plug if it comes out clean with no thread damage. THEN put some Teflon tape on the plug threads when you reinstall it or a generous dosing of anti-seize. I prefer the Teflon tape because it wont wash or wear away in the oil pan.

I also think I would look at moving that FEL bracket so it isn't directly under the drain (PxxPoor design having it there to start with). This might be something your welding shop could do while it is there.

I think he said it was hydraulic system being drained. Usually don't want to use Teflon near hydraulic.

Don't over think this job. Once broken loose could snug by hand and drive home to finish up. Install new plug and don't overtighten; just snug up with a little 1/2" X 9/16" wrench and done. Maybe invest in an 8 point socket, but not necessary.

From the picture, I would virtually guarantee that I could get that plug out with my 18" aluminum Rigid pipe wrench, and maybe a short cheater. Wrench is $60 at Home Depot.

The problem with most pipe wrenches is the wide body of the wrench. The jaws are narrower than the body. Due to the wide flat bottom of the tranny pan and the short 1/2" length of the plug head, the body of the wrench will hold the jaws down far enough that they barely have any bite on the plug.
