How much does an allis chalmer hd5 weigh?

The general rule on old Allis Chalmers equipment is found in the model designation--an HD5 is about 5 tons for the bare crawler--an HD7 is seven tons and an HD9 about nine tons and the HD11 around eleven tons. You have to add the weight of the blade, winch canopy and belly pans which can add several tons to the final weight--but the basic crawler weight is in the model designation.
