ABSTRACT:
A post extracting device having a frame, a ram supported on the frame with a piston extending outwardly therefrom, and a chain affixed to the piston. The ram serves to move the piston from a retracted position to an extended position. The chain is suitable for wrapping around the post. The ram pushes the chain upwardly so as to extract the post from the earth. The ram is pivotally mounted to the frame so as to be movable between a vertical orientation to an orientation angularly offset from vertical.
