An extractor for removing a manhole cover including a central bar member. The central bar member includes first and second hooks that extend below the central bar member and first and second threaded fasteners that extend through the ends of the central bar member. The width of the central bar member may be adjusted to align the hooks with bars in the manhole cover. When the hooks are hooked onto the bars and the threaded fasteners are turned, the threaded fasteners exert downward pressure on the surface surrounding the manhole cover such that the central bar is raised and the hooks lift the manhole cover.
