Allows the easy action of raising and lowering of the Postdriver mast via a Hydraulic Ram that can be operated at the finger tips of the machine operator. Ideal for travel on roads, or where overhead wires are present. Also great for storing your post driver in a shed. A ball valve locks the ram in the working position. You do not need to remove the rope or use a bolt to secure the mast. Quick, easy and safe to use.
