skid steer high back pressure paving breakers** NEW **
Now you can use your skid steer, backhoe, excavator or tractor to power your 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)
  • *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 warranty 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.
OIL DIVIDERS (Required with all skidsteer)    
  Use your auxillary hydraulics port to power your hydraulic tools by connecting an oil divider and extension hoses.
