Abstract (en)
A post driver (1) has a support frame (2) with means (3) for attachment to the three point linkage of a tractor. A hammer (10) is slidably mounted on a mast (5) for driving a post beneath the hammer (10). A rock spike holder (44) carrying a rock spike (41) is pivotally mounted on the mast (5) for movement of the rock spike (41) between a stored position and an in-use position beneath the hammer (10). A spike extraction ram (52) on the mast (5) is operable to raise the rock spike holder (44) from a lowered position to a raised position for extraction of the rock spike (41) from the ground. A spike extraction support leg is provided at a bottom of the mast (5) to engage the ground as the spike is being extracted.
