Big Gus is the largest chainsaw in the world according to the Guinness World Records. This enormous tool measures 1.83 m (6 ft) high and 6.98 m (22 ft 11 in) long.
It was built by Moran Iron Works, Inc. of Onaway, Michigan, USA in 1996 and after all these years, it is still admirable and amazing to watch in action. Once the chain gets going on this thing, we can see how truly powerful it is.
