Here's this compact, quiet tool...and it hits harder than any other type of breaker.  That's because hydraulics are more efficient than electric, pneumatic, or petro-driven tools.  For example, a 70lb hydraulic breaker gives you the same hitting power as a 90lb pneumatic.  Thanks to their amazing impact energy, hydraulic breakers can be used on concrete, asphalt, and frozen ground.  You can, of course, also use them for trenching, tie-tamping, spike driving, and general demolition.
The LH 390 is probably the most powerful handheld breaker in the world. It is used for the most demanding jobs in heavy asphalt, reinforced concrete and foundations.

Features & benefits

  • Low noise levels
  • Slim design
  • High power to weight ratio
  • High back pressure (HBP) version for skid steer connections


  • Medium and hard materials as asphalt and concrete
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).
*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.
