Engine-Powered Log Splitters: Large-Volume Firewood Without Mains Power

A vertical model suits heavy, thick logs that you do not have to lift, while a horizontal one splits medium logs quickly. Combination models work in both positions, and towable versions can be pulled by a car or tractor. Read what motor tools and engine-powered equipment are and how to choose them.

Engine log splitters usually deliver 7–30 tonnes, and 15–20 tonnes is enough for most hardwoods. A two-stage pump speeds up the unloaded wedge stroke and brings cycle time down to 10–20 seconds. Choose the force for your wood species and diameter with a margin.

These machines usually have a 4–7 hp (150–220 cm³) four-stroke petrol engine. Engine size and power affect pump output, and a four-stroke engine does not need an oil-petrol mix. Read differences between two-stroke, four-stroke and diesel engines and engine displacement, power, torque and RPM: how to compare engine-powered equipment.

Engine models take logs 50–110 cm long, so you can also split wood cut to long lengths. A log lift and work tables make handling heavy logs easier. A cross wedge splits a log into four pieces in one cycle.

Use quality petrol and check the engine oil, hydraulic oil and filters. At the end of the season, drain the fuel tank or add a stabiliser. Read fuel, engine oil and two-stroke mix: how to choose and use them correctly, how to maintain and store motor tools and engine-powered equipment and how to choose spare parts for gasoline and diesel engines.

Engine log splitters weigh 100–400 kg, so large wheels and a tow bar matter. Some models can be towed on the road at low speed, while smaller ones are moved by hand. Check the parking stands and stability in the working position.

Use the two-handed controls and never hold the log by hand while the wedge moves. Wear gloves, glasses and hearing protection, and run the machine outdoors only. Read how to safely use internal-combustion-engine tools and equipment and how to choose personal protective equipment.
