The Greenlee HRD-58 Hydraulic Ground Rod Driver is a rugged hydraulic tool engineered for utility and construction professionals who need an efficient method for installing grounding rods. The driver is a hydraulically powered reciprocating tool designed to drive ground rods of various lengths, delivering strong impact performance while maintaining reliable operation in field conditions.

The HRD-58 is designed to accommodate ground rods up to 5/8 in. (16 mm) in diameter, making it suitable for many standard grounding installations. A deep rod opening and smooth operating action help keep the driver securely positioned on the rod during operation, while dual guide rods provide improved control to help drive rods straight.

The driver includes a remote on/off control valve that enables operation with both open-center and closed-center hydraulic systems, allowing compatibility with a wide range of hydraulic power units used by utility crews. The hydraulic system operates within a 5-8 GPM flow range with a maximum input pressure of 2,000 PSI, delivering 63 ft-lb of blow energy and approximately 1,740 blows per minute at 8 GPM for efficient rod-driving performance.

Constructed for durability and ease of use, the HRD-58 measures approximately 25-1/2 inches in length and weighs about 45 lb without hoses and control valve, providing a balanced design for demanding field applications. With its powerful hydraulic performance, controlled operation, and durable construction, the Greenlee HRD-58 offers a dependable solution for professional ground rod installation in utility and infrastructure projects.
