The Ottomeyer Mammut is the largest plow ever made. It was created for the specific purpose of converting bogs into agricultural land and could cut channels in the ground to a depth of over 2 meters.
The bog areas of the Emsland district in Northern Germany, on the border with the Netherlands, had been determined uninhabitable since the 1700s, but in the early 20th century, the government of Western Germany decided that the region had fallen behind the rest of the country economically and needed to be converted into arable land. That was easier said than done, however, as the bogs had kept farmers away for hundreds of years, but the Germans had an ace up their sleeve – Otto Meyer, a brilliant engineer and inventor who specialized in steam tractors and difficult soil cultivation.
