YouTuber Builda Dad Garage builds extraordinary vehicles in his workshop, mostly extreme vehicles designed to tackle the roughest environments. These include tracked wheelchairs, dually go-karts, minibikes with mower attachments, a bike that rolls on barrels, and amphibious trikes.
One of his recent inventions is a mechanized ladder that can push through snow and over obstacles thanks to rear-mounted tracks. It's an ideal machine for, say, clearing gutters. This way, you don't have to climb down and reposition the ladder every few feet. Just stay at the top and drive.
He also made a wheeled variant for, presumably, transportation over roads.
