The Greenlee HPD-T-U Hydraulic Post Driver with Universal Post Adapter is a professional hydraulic driving tool designed to simplify the installation of signposts, fence posts, and other types of driven posts. Engineered for versatility, the driver can install multiple post styles and sizes-from small delineator posts to round posts up to 3-1/2 inches in diameter, including square, U-channel, breakaway stub, T-fence, and wood posts.

The tool features a quick-change front head design that accommodates adapters for different post types, allowing operators to quickly switch between configurations depending on the installation requirements. Dual guide handles provide improved directional control during operation, helping the operator keep the driver aligned with the post. In addition, the deep post opening and smooth operating action help ensure the driver remains securely positioned on the post without jumping off during use.

Powered by hydraulic systems with a 5-8 GPM flow range, the HPD-T-U delivers 81 ft-lb of blow energy and approximately 1,500 blows per minute at 8 GPM, providing the impact power needed to drive posts efficiently. The driver is compatible with both open-center and closed-center hydraulic systems, increasing its versatility with different hydraulic power sources.

The unit measures approximately 32 inches in length and weighs about 75 lb with the universal adapter and hoses, providing a durable and stable platform for demanding field work. With its high-impact performance, adaptable head design, and operator-control features, the Greenlee HPD-T-U Hydraulic Post Driver offers a reliable solution for road crews, contractors, and utility professionals installing posts in a wide variety of applications.
