LH 400E HBP Paving Breaker

The LH 400 E 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.


  • Operator Friendly - Low vibration values, low noise levels and slim design makes this breaker a tool to use for many years to come
  • You've Got Power - High power to weight ratio means you get more done with a smaller breaker
  • Ergonomic - The vibro reduction abilities of this breaker lets you work for more than eight (8) hours without risking injuries


  • 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  (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.
