Abstract
A body member has an upright bore for receiving a stake to be pulled. When the body member is tilted, edges of the bore grip the stake. A flexible link has one end connected to the body member and its other end arranged to receive a lever that is used to impart an upward lift on the flexible link which in turn tilts the body member for gripping the stake and applying an upward pulling force to the stake.
