Triple Butterfly Mowers - Sickle bar type

I saw this a while ago but didn't save the link maybe someone else has already posted. I think the double 9 ft rowse mowers are about the widest sickle bar outfit commonly around in North America but European has front mount with butterfly rear, looks to be close to 45 ft mowing on 100 hp?
