Big Bull, released in 1975, was a hot rod bulldozer and was released to accompany earlier hot working vehicles such as Mod Tractor and Rod Roller. The upper body was painted yellow-orange and had a 'chopper' style canopied seat. The chassis and dozer blade were a metallic mid-green whilst the Cobra engine, hood scoop, grille and seat were chromed plastic. The wheels were orange and the rubber treads were usually black but sometimes they were green ones left over from an earlier model, Case Tractor. Somewhat peculiarly, there was a slot for a steering wheel but no actual steering wheel and it had a towing hook though no trailer was ever made for it.
