Note: The optional 4-1/4" master chuck lets the PD-55 run PD-110 chuck adapters.
The Rhino PD-55 Master Chuck is the foundation of the PD-55 post driver system. The standard 3-7/8" (98.4 mm) ID chuck accepts a full range of bolt-on chuck adapters, so one driver can handle nearly any post profile in the field. Built for medium-duty production driving, it keeps the full impact force on the post centerline for clean, plumb drives across post types and soil conditions.
