There's no way to view this in-game as it has been deleted, and probably will not be added back into the game in the near future, as it has been removed from the game either partially or entirely.
"Seven seconds have passed... ROAD ROLLER!!!"-High DIO Part 3 (DlO, ディオ).
The Bulldozer is a tractor equipped with a substantial metal plate (known as a blade) used to push large quantities of soil, sand, rubble, stone or other such material during construction or conversion work and typically equipped at the rear with a claw-like device (known as a ripper) to loosen densely compacted materials. It is usually a crawler (continuous tracked) tractor. Inside the window, the owner of the game, TheGuestToBlame can be seen operating it.
The Bulldozer has a mostly yellow color-scheme and is shaped like a truck. The wheels, however, look like Continuous track, also known as the wheels of Tanks.
The Bulldozer in-game is also seen to be pushing dirt to create a path from the tunnel behind it to where it is now.
There was also a tunnel/cave behind the Bulldozer, where the Enhanced Holodummy used to reside. On the right side, Bob can be seen fishing in the Grassy Bay. A few buildings to the right of the Bulldozer is where Tom's Shack is located.
TheGuestToBlame used to carry his Pot Platinum with him while inside the bulldozer, however, it was deleted after the "New Map" update.
