A log splitter is a machine that splits firewood into smaller pieces using hydraulic pressure. It saves time and physical effort compared to splitting logs manually with an axe.

Splitting force is measured in tons (t). For general home use, 4–7 tons is usually enough. For tougher or larger wood like birch or oak, you may need 8–12 tons or more. Professional use often requires 15–30 tons of splitting force.
