The ornamental design for a concrete stakepuller, as shown and described.
FIG. 1 is a perspective view of a concrete stake puller showing my new design in use;
FIG. 2 is a front elevation view of the puller.
FIG. 3 is a side elevation view thereof.
FIG. 4 is a rear elevation view thereof.
FIG. 5 is a bottom view thereof; and,
FIG. 6 is a top view thereof.
The concrete stake and workman shown in broken lines in FIG. 1 denote the nature and environmental use of the design and are not part of the claimed design. The protective covering shown in broken lines on the handles in FIGS. 2-6 also forms no part of the claimed design. The graphic symbol used on the shaft of the concrete stake puller and on the right and left handles indicates no particular length; the claim is directed only to those portions of the design that are disclosed in solid line.
