Hello,

this is "Big Bud 747", world's largest farm tractor. It has an internal V16 diesel engine and delivers 900-1000 horsepower.
It is custom-made, so there is only a single exemplar. It was designed for pulling works only, so there is nothing to attach machinery to at the front. During its lifetime it found use on different farms in different states of the US.

This Big Bud 747 was built on a pretty close but not entirely exact 3:2 scale.

Enjoy!
