Every logger needs to have a dozer around just in case something needs shoved.
This high performance Fiat Allis 31 features a 425 Horsepower Cummins KT1150 engine. The working weight is around 70 tons, and the blade is 18 feet wide. As with anything that weighs 70 tons and is 18 feet wide, moving it is not easy, but with the blade off, the width becomes reasonable and it can be hauled without further dismantling if you can get enough permits. Smaller dozers are more popular in applications where they must be moved a lot for obvious reasons. It was manufactured by what is now known as FiatAllis North America although they no longer market a machine this large in North America.
