A friend had to move a 500lb concrete firebowl 25 feet across his lawn.
Preferably without busting anything.
The curved sides made it pretty much impossible to lift.
We had to start outside the gate here...
...and get to the patio there. The slight issue was that it had to be elevated
about 8" to clear a permanent gas riser (arrow), then back down so the riser would fit
up through a hole in the bottom of the bowl.
All you need is 10 blocks of ice. Turn off the gas first. Just in case.
