I came across a weird machine the other day.
I just spotted this very elegant parasol which looked like it was gliding over the tops of the vines, so I stopped to ask what was going on.
The vineyard belongs to Champagne Mumm, the tractior is state-of-the art and is GPS guided, but the bit at the back look as if it has come out of a museum.
Take a look at the video and see if you can guess what they are doing before the answer appears on the screen.
Still, I guess this chap is grateful that he doesn't have to do it by hand.
Here's the video.
