Name on box: Bulldozer with horn and light!
Manufacturer: Linemar, Japan
Dimensions: Length - 9.5" Width - 5.75" Height - 6.5"

Actions: Bulldozer moves in bump and go fashion as steering levers move back and forth creating the impression that robot driver is controlling the direction. The rear rubber tread wheels roll along the ground, which in turn cause the front tread wheels to turn, creating the impression that the bulldozer is being propelled by the rubber treads. Intermittently, the horn will sound and the light atop the robot's head will light.
Additional info.: Photo above depicts the yellow color variation. There is also a blue color variation. Variations to the lithography of the robot operator also exist. Stamped into the center of the bump and go plate on the bottom of the toy is the Linemar Toys logo and the word JAPAN.
