Good old TC contest to make me build something. This Will hopefully be a retro, self styled (not copying real one) bulldozer and some styling I have in mind reminded me of an old cartoon character that shares a name with this topic name. Pneumatic functions and air tank will be fed by two small pumps driven by the tracks.       some over all proportions I’m working to below -blade will have lift, tilt and turn -hopefully a rear ripper thingy
