This is a Greenlee 1" ground rod driver used to install ground rods that stabilize large towers or structures. This hydraulic tool is much easier to use than driving them in with a sledge hammer especially in hard soil conditions.

Features

A deep rod opening and smooth operation ensures that the driver will not jump off of rods.
Light weight allows easy mounting on top of rods.
Can be used with open and closed center hydraulic systems.
Dual guide rods provide excellent control for driving rods straight, and the remote on off valve makes it easy to control the depth of the rod.
