I have a 4-foot metal post next to my driveway, installed by a previous owner, that once supported a basketball hoop. It's a fairly thin-walled tube about 4 inches in diameter, embedded in a huge block of concrete, buried in the lawn. I've tried excavating around the block, but it will be a really big hassle to get out of the ground. And so, the pole remained there for many years.
I'd be just as happy cutting the pole off at ground level. If I can cut if off flush with the concrete, it will hardly be visible and it won't interfere with the mower. I don't want any of the metal to stick up.
My question is, what common tool can I use to cut this thing? I wouldn't enjoy doing it manually with a hacksaw, and anyway, I don't think I could get close enough to the ground. Could I cut it fairly close, then grind the rest down with something?
Any suggestions?
