 The Tamiya "Bullhead" which was released November 13, 1990 utilises the same basic chassis design as the Clod Buster, albeit moulded in different coloured plastics.The most significant difference is that it carries a taller semi-tractor type body, likely inspired by fullsize semi-bodied monster trucks such as "Super Pete".The other differences between the Bullhead and Clod Buster (other than the body) lie mainly in the color of the plastic used for various parts.
