ABSTRACT:
A device for the extraction of fence posts having a T-shaped cross-section. The device is arranged to engage the fence post in a frictional binding action on the post when tilted by the upward application of force to one end of the device. The upward application of force is derived through cooperation with a jack, whereby the tilting of the device secures the device in position with the fence post and transfers the upward force from the jack through the device to the fence post. The tilting of the device also secures the jack to the device, thereby ensuring cooperation between the jack, the fence post, and the device throughout the full length of the lifting stroke.
