ABSTRACT:
Ratchet operated device for setting a post having a helical auger thread disposed at one end. The ratchet operated device has an annular sleeve with an annular series of teeth disposed on its exterior surface. The annular sleeve is provided with a fastener for securing the annular sleeve to the post. A collar coaxially fits over the annular sleeve such that it circumscribes the annular series of teeth. Attached to the collar is a handle, preferably one that is removable to facilitate transporting and storing. Radially extending through the collar is a bore in which there is disposed a ratchet mechanism. The ratchet mechanism has a pawl which is biased to engage the annular series of teeth. The profile of the pawl provides positive engagement of the pawl with the annular series of teeth when the collar is rotated in one direction, while providing an overrunning action when the collar is rotated in the opposite direction. The pawl is rotatable between a first position and a second position such that the ratchet operated device is able to both install and remove a post from the ground by reversing the position of the pawl.
