If you're going to build a road, or just move the earth, you have to have bulldozer.

       Our rugged little machine is 5-1/2" long x 4-3/4 x 3-1/2" high.  It is constructed of oak, walnut, and maple.  The driver is removable so he can get out to check his work.  This bulldozer rides on wheels that are hidden inside the tracks.
