Greenlee HPD-HV-U Sign Post Driver

Greenlee Fairmont HPD-HV-U hydraulic sign post driver with remote valve and universal post adapter. These are a big seller with state and local DOT as they make installing road signs much easier then a manual post driver.

the hydraulic flow between 5 to 8 GPM and keep the pressure under 2300 PSI.
