I'm not sure I would have been able to guess what this 'was' without your explanation, Andrew - but the photograph is phenomenal. And beautifully processed, too. It makes me think of some pieces I've seen in great modern art museums, it has visual and spatial qualities which make me keep on staring at it. Great image.
Outside a very old out-building, is a nearly-just-as-old manual lawn mower, that was rescued from beneath a small mountain of ivy and dirt where it had lain (hibernating?), for decades. Now it sits out in fresh air, possibly storing up solar energy for a future tour of duty.
