ABSTRACT:
A tool for the extraction of wood or metal stakes and poles from the ground. In the preferred embodiment, the tool includes a vertical support attached to a base, a lever arm, a stake engaging head having plurality of arms and a positioning handle, and an elongate connecting member connecting the head with the lever arm. The connecting member can be positioned at different locations along the shorter lever arm providing different leverage options to the user when unusual resistance to removal is encountered. The engaging head has a face with a fixed projection and an adjustable projection. The stake or post is placed between the two projections which frictionally engage the stake. The adjustable projection on the head allows the device to receive essentially any size of stake or post. In the alternate embodiment, all of the projections on the engaging head are fixed in positions which correspond with conventional wood and metal stakes. The positioning handle attached to the engaging head can be secured to the top of the device and retained with a clip for easy transportation and storage.
