Deere high speed dozer!
You're probably thinking "What the heck! Why don't they use a normal dozer??"
This particular project, being a highway job, has an extremely long site boundary. There are miles of road involved and many smaller projects happening at once. The high speed dozer has the ability to jump between each of these projects very quickly, allowing it to be utilized all day long. A regular D6T, of which there are plenty out there as well, would need a low boy to transport it from location to location. This dozer is less capable than a D6T but it's speed and agility makes up for it.
