Rhino PD-140 Master Chuck
The Rhino PD-140 Master Chuck is the foundation of the PD-140 post driver system, accepting a full range of bolt-on chuck adapters to match the driver to virtually any post profile in the field. With a 4-1/4 in. inner diameter and built for heavy-duty production driving, the master chuck transfers full impact force directly down the post’s centerline for clean, straight drives on the toughest posts and soil conditions.
