Compact size yet heavy duty the 13 HPWS is ideal for most firewood operations. Towable from both ends, this machine can be pulled away from the wood pile and on the highway. The auto-cycle valve allows the cylinder to go out though the block and back on its own, giving you time to get your next block ready. The 4 way hydraulic wedge retracts down below the splitting beam, allowing you to split 2 ways without the hassle of removing wedges.
