Abstract
A stake puller for extracting a stake from a portion of a substrate (e.g., earth, soil, or the like) wherein the stake is abutted against a perpendicular wall that thereby exposes a side portion of the stake opposite of the perpendicular wall between the portion of the substrate and an exposed top of the stake, the puller including: a shaft having a distal end and a proximal end; a cross-handle coupled to the proximal end; and a stake-engaging head, coupled to the distal end, engaging the exposed side portion of the stake between the portion of the substrate and the exposed top from a direction opposite of the perpendicular wall wherein a longitudinal axis of the shaft is generally parallel to a longitudinal axis of the stake when the stake-engaging head engages the exposed side portion of the stake.

A stake puller for extracting a stake from a portion of a substrate wherein the stake is abutted against a perpendicular wall that thereby exposes a side portion of the stake opposite of the perpendicular wall between the portion of the substrate and an exposed top of the stake, the puller comprising:
- a shaft having a distal end and a proximal end;
- a cross-handle coupled to said proximal end;
- and
- a stake-engaging head, coupled to said distal end, engaging the exposed side portion of the stake between the portion of the substrate and the exposed top from a direction opposite of the perpendicular wall wherein a longitudinal axis of said shaft is generally parallel to a longitudinal axis of the stake when said stake-engaging head engages the exposed side portion of the stake.
A method for extracting a stake from a portion of the substrate wherein the stake is abutted against a perpendicular wall that thereby exposes a side portion of the stake opposite of the perpendicular wall between the portion of the substrate and an exposed top of the stake, the method comprising the steps of:
- a) engaging the exposed side portion of the stake between the portion of the substrate and the exposed top from a direction opposite of the perpendicular wall with an engagement head coupled to a distal end of a shaft with a longitudinal axis of said shaft generally parallel to a longitudinal axis of the stake;
- b) applying a longitudinal force to said shaft directed away from the portion of the substrate;
- and
- c) transferring said longitudinal force to the stake through said coupling of said engagement head to said shaft.

- a shaft having a distal end and a proximal end;
- a cross-handle coupled to said proximal end;
- and
- a stake-engaging head, coupled to said distal end, engaging a side portion of the stake between the portion of the substrate and a top of the stake wherein a longitudinal axis of said shaft is generally parallel to a longitudinal axis of the stake when said stake-engaging head engages said side portion of the stake.
