Breaking up old concrete?

[TheGrooveking]

Drill some holes in it and it should break between the holes.

This too is what I recommend, then use a large sledge, 12 or 16 pound and it will break into pieces.

Pretty much anything that small that comes from the factory with a backhoe these days is subframe mounted. Those category 0 3 points are practically worthless.

I have the same BX25D tractor and the hoe is frame mounted. It is the only tractor in the BX group that comes with a hoe. Mine has a thumb and can do a lot of work for it's size.

I dug out the concrete in my garage to pour new stuff. At first the rented electric jack hammer was taking forever, so I hired some guys at the local Home Depot and they did it much faster than me. They were leveraging the pieces / jackhammer as they went. I was more or less going straight up/down since there was a sign on the jackhammer I rented that said don't bend it. Yeah next time I'm leveraging as I go!

I'm breaking up a 16 by 20 4" slab this weekend that was likely poured in the 40's or 50's. Using a tracked bobcat/loader and will get under it and pop it in pieces. If that doesn't get it Ill hit it with a 20lb sledge after I lift it up a bit.

This ^^^ is how it's done.

If you have electricity and air nearby try using a simple air hammer and pointed tip. I've chopped all the shale heads in my yard the hoe wouldn't touch and it works far better than beating with a sledge. It's also the only thing that would cut through my basement wall to install a 4" pipe. Hammer drills were a joke but the 20 year old $10 pneumatic hammer did it with EASE. Hard to believe I know
