I have some of those welded on the end of 20" rebar stakes. I don't think a yote can jack those stakes out of the ground. I don't use many because I don't like to pull them back out of the ground Getting old isn't fun. Lol
They're pretty hard steel. Would use up some drill bits drilling holes for the cable. But I think it would work. They sure wouldn't bend and they have more surface area than most earth anchors. I don't know if you'd ever get them back.
Found a brand new one just like that last year at the farm I hunt. No hay anywhere near that place so I'm guessing they use that same machine to cut left over corn stalks down close to the ground. Found it a few days after the farmer did it.
That's what all my disposable stakes are. Made a driver out of stainless round stock. You gotta pull up hard when you drive them in rocks cause they don't bend they occasionally break.
