Combine harvesting in Burgundy

We all think grape harvest in Burgundy is only done by hand but I spotted this combine in the Côtes-de-Nuits area, busy machine-harvesting a parcel of what looked like Chardonnay. It's probably a lower parcel located on flatland outside any Appellation zone (there was a corn field just on the other side of the road). Pretty violent on the vines and foliage, at some point I was struck with flying debris hitting me with high speed and chose to stop walking further behind the machine...
