ABSTRACT:
A stake puller (10) for use in removing a stake (4) lodged in the ground (2) utilizes a lever (12) and fulcrum (20) for mechanical advantage. The stake (4) is positioned between a blade means (30) fixed to the end of the lever and a back plate (40) pivotally attached to the blade means. When the user pivots the lever down, the stake is pinched between the forward edge (34) of the blade means (30) and the primary surface (42) of the back plate (40). The primary surface (42) is curved and diverges from the stake. This minimizes any bending or friction forces applied to the stake.
