"unlike most bulldozers" seems to heavily imply it's still a bulldozer: "Unlike most bulldozers, most loaders are wheeled and not tracked, although track loaders are common. They are successful where sharp edged materials in construction debris would damage rubber wheels, or where the ground is soft and muddy. Wheels provide better mobility and speed and do not damage paved roads as much as tracks, but provide less traction." http://en.wikipedia.org/wiki/Loader_(equipment) http://en.wikipedia.org/wiki/Loader_(equipment)
