I'd like to have a fire pit, but don't want it permanently in the garden. I am thinking of making one that can be moved, either like a wheel barrow, or a sled that can be rolled with a riding mower.

It would sit on grass while it is used, so it needs some heat protection so the grass does not get damaged. I am thinking this could just be some pieces of plywood as long as the pit is not too close to the ground.

Has anyone made such a beast?
