HPD-16 and Q-Series SWO Offset 3-pt Hydraulic post drivers.
Driving post along existing fence lines, ditch banks, or corners is easily done with a SWO model. Hydraulic side shift extends the unit 24” to the left permitting the post driver to reach up to 46” left of the tractors center point. Heavy-duty 3-angle swivel mount pivots the driver 45°, 90° or rear facing for increased versatility. Slide tension adjusters provide easy extension of the unit, while providing support when extended. Two trailer hitch locations are standard.
