SCRAPER

Here is a large scraper. Being realistic, lifesize scrapers can  have tires with a diameter of 6ft. to 8ft in length..

Here is a picture of my updated model. The tires have been upgraded to 2' technic hubs. This thing measures ten studs wide and thirty-six studs long. It's all finished, with a little execption. The bowl only needs thin panel walls.

Here is my first prototype (top). Not much has changed between the two pictures
