While the 250/B2 remains the gold standard for landowners and smaller firewood operations, the 400/B was forged for those who need more.  More speed.  More muscle.  More profit.​  With a 1.7 second cycle time, & 40 tons of force, there isn't a log on your yard that can stand in its way.
  • Power + Unmatched Efficiency: Go from small, easy-split species to ugly knotted hardwoods, without switching machines or slowing down.
  • Precision Control: Our new electronic single joystick and log clamp with roller, make this machine easy to run, & reduces operator fatigue.
  • Built for the Long Haul: Larger metal fuel and bar oil tanks mean fewer stops and more firewood on the ground.
Below is a comparison showing both machines, including the main differences & standard features on both machines.  The 250/B2 & 400/B are built on the same basic frame, with the splitter beam on the 400/B being a bit stronger to handle the increased splitting force.  Comparisons show standard features on both machines.
