At first glance you might think this is a lawnmower, but I believe this is actually a geophysical survey being carried out around the sinkhole that opened up in Canynge Road garden over Christmas. Looks like a geophysicist using ground-penetrating radar to me, anyway. I've seen Time Team!
Ah, there's something of a clue: his hi-vis tabard says "Fugro" on the back. That's Ingenieursbureau voor Funderingstechniek en Grondmechanica, Dutch for "Engineering Company for Foundation technology and Soil Mechanics". Sounds fairly ground-survey-ey to me.
