Abstract:
A method of removing a T-type fence post from the earth with a powered, mobile piece of equipment controlled by a human operator includes attaching a substantially flat plate to a lift arm of the powered, mobile piece of equipment such that the plate hangs substantially vertically from the lift arm and can move in an arc, the plate having an opening with a top wall and a bottom wall, moving the powered, mobile piece of equipment in a first direction to pull the plate over the fence post such that an upper portion of the post enters the opening with the bottom and upper walls of the opening engaging the post with sufficient force to retain the post in the opening when the post is pulled from the earth and raising the lift arm to pull the post from the earth in a substantially vertical direction.
