LPD-T High Back Pressure Post Driver

Used for driving road barrier tubes, profiles, signposts, fences and a wide range of anchors. The post drivers provide stable, powerful, high speed driving for a variety of post sizes. When operated with an optional hose-mounted remote-controlled valve, the drivers can be run with both open- or closed-center systems.

HIGH BACKFLOW PRESSURE - Now you can use your skid steer, backhoe, excavator or tractor to power your Breaker or Post Driver. These tools are designed to work with high back pressure and represent a breakthrough in versatility. These units are able to work on a maximum return/back pressure of 400 PSI (200 PSI for non-high back pressure units). Flow requirement of 8 gpm (Same as non-high back pressure units). Working pressure at approximately 1500 to 1800 PSI with maximum relief valve setting at 2200 PSI. (Same as non-high back pressure units).


  • Built in on/off valve for short pole driving
  • Drives up to 96 mm diameter poles
  • For driving:
    • Road barriers
    • Tubes / profiles
    • Signposts
    • Fences
    • Anchors

*To ensure that the tool is receiving the correct flow of 8 gpm, you will need OFD 30 Oil flow divider part #1801 1642 32 Oil flow Divider (Max flow in: 32 gpm; max. pressure: 3,600 psi). No warrantee for tools damaged by over pressure when run without an oil flow divider.

**For John Deere and Bobcat skidsteer that deliver between 16 and 30GPM. Pressure Reduction Hoses must be used in conjunction with the OFD.
