Hydraulic Log Splitter for Mini Excavator

Hydraulic Splitting on a Mini Excavator: Screw, Not Wedge

Log splitting with a hydraulic wedge requires a steady flow and stable pressure. This model, connected to the auxiliary circuit of a mini excavator, takes a different approach: a conical screw that penetrates the wood through rotation. The unit is supplied with hoses, which addresses some of the mounting questions in the field. The 25 mm mounting pin matches the most common hitches on compact excavators for operators who already switch between buckets and specialized tools.

Operating Ranges to Respect

The mechanics are straightforward. The allowable flow rate is between 15 and 30 L/min, the rotation speed between 40 and 100 rpm, and the working pressure must not exceed 16 MPa. These three parameters are set from the carrier machine. Too low a flow prevents the screw from spinning fast enough to initiate the split; excessive pressure stresses the components. The allowable wood diameters depend on moisture content: 150 to 260 mm for wet wood, 200 to 300 mm for dry wood, with a maximum length of 500 mm in both cases.

Technical Specifications

The screw itself has a diameter of 80 mm, a height of 220 mm, and a total height including the shank of 380 mm. These dimensions are provided for pre-mounting validation: an operator who knows the pin spacing of their quick coupler will immediately know if the tool fits their existing fleet.

Consistency with a Hydraulic Range

This type of tool integrates into a lineup of attachments already proven on the same carriers. For finishing work or hedge maintenance, a hydraulic hedge trimmer for mini excavator shares the same connection logic on the auxiliary circuit. For sorting or cleanup after splitting, the 80 cm sorting grid bucket removes chips and sawdust. For those handling volumes of brush before splitting, the 64 cm hydraulic mulcher already reduces intermediate diameters.
