A portable hydraulic stake puller includes a hydraulic cylinder that extends to raise a jaw assembly. The jaw assembly pivots, while being raised, to grab and trap the stake. A grab hook may alternatively extract similar items not readily removable with the jaw assembly. The jaw or chain tension is controllably released when the control lever is released at any height of the stroke. Squeezing the control lever can again attain grip easily. The gripping action of the jaw is attained by at least friction against the jaw. When the control lever is released, the entire lift assembly returns to the neutral position under a spring tension. The hydraulic stake puller is mounted on wheels and controlled via handles allowing easy maneuvering.
