JANSEN® HS-20H110 Log Splitter – 20 metric tons of splitting force, 110 cm splitting length, and a 6.5 PS KOHLER gasoline engine

The JANSEN® HS-20H110 is a powerful, gasoline-powered log splitter designed for demanding firewood processing. With a splitting force of 20 metric tons—actually measured at the splitting wedge—, a maximum splitting length of 110 cm, and a robust 6.5 PS KOHLER gasoline engine, the machine delivers ample power for large and heavy logs.

A special feature of the HS-20H110 is the additional hydraulic cylinder for convenient raising and lowering of the machine. This allows the massive wood splitter to be moved hydraulically between the transport and working positions.

Important: The JANSEN® HS-20H110 is intended exclusively for vertical splitting and must not be operated in a horizontal position.

Thanks to its own gasoline engine, the log splitter operates independently of a power connection or tractor, making it ideal for flexible use on your property, in your yard, or at suitable locations in agriculture and forestry.

20 metric tons of splitting force for demanding wood-splitting tasks

With a splitting force of 20 metric tons, the JANSEN® HS-20H110 is designed for demanding splitting tasks.

The splitting force on our wood splitters is measured directly at the splitting wedge. The specified splitting force therefore corresponds to the actual value applied there.

Combined with the solid splitting wedge and robust hydraulics, the HS-20H110 offers high power reserves for regular firewood processing.

110 cm actual splitting length

Another key advantage is the generous maximum splitting length of 110 cm. This is the actual maximum dimension of the log being processed.

The cylinder piston stroke is 100 cm. This allows the splitting wedge to travel a great distance through the wood, ensuring a reliable and complete splitting process.

This long piston stroke is a major advantage, especially when dealing with long or stubborn pieces of wood, as the wood is split almost all the way through and does not require unnecessary reworking.

Hydraulic Raising and Lowering

Weighing approximately 340 kg without fluids, the JANSEN® HS-20H110 is a solidly built machine. To ensure that switching between the transport and working positions can still be done comfortably, the log splitter features an additional hydraulic cylinder.

This cylinder allows the machine to be raised or lowered hydraulically, which significantly simplifies handling of the heavy log splitter.

Please note: The lowered position is for transport. Splitting operations may only be performed when the machine is fully raised or in the upright position.

Powerful 6.5 PS KOHLER gasoline engine

The hydraulic pump is driven by a high-quality KOHLER 4-stroke OHV gasoline engine with 6.5 PS or 4.8 kW.

This allows the JANSEN® HS-20H110 to be used independently of a power source or a tractor. This makes it particularly appealing to users who want to process firewood right where it is harvested.

The engine is easily started using a recoil starter. The fuel tank has a capacity of approximately 3.6 liters; fuel consumption is approximately 1.0 to 1.2 liters per hour.

30 cm splitting wedge & splitting cross included

The HS-20H110 is equipped with a solid 30 cm long splitting wedge. Additionally, a 30 cm long splitting cross is included in the scope of delivery.

The splitting cross is simply slid over the existing splitting wedge. This allows you to switch between the normal splitting wedge and the splitting cross in no time.

The generous length of 30 cm ensures a complete splitting process, especially with thicker logs, without having to rotate the wood unnecessarily or reposition it.

Precisely Controllable Hydraulics

The hydraulics of the JANSEN® HS-20H110 are designed so that the splitting wedge can be stopped in any position. It can then be moved forward or backward as needed.

As a result, the splitting wedge does not have to return fully to its starting position after every splitting operation, for example, when splitting shorter pieces of wood. Unnecessary travel can be reduced, and the workflow becomes more efficient.

A full cylinder cycle takes approximately 12 seconds downward and approximately 11 seconds upward.

Optimized Design for Practical Use

The JANSEN® HS-20H110 has been continuously optimized throughout its product development. In the current version, the controls are located directly on the cylinder, which improves accessibility during operation while the machine is upright.

In addition, numerous flexible hoses have been replaced with permanently mounted metal lines. This ensures a clean and robust design.

In the current version, the wheels are mounted on ball bearings, thereby ensuring smoother operation when moving the machine.

Transport with a drawbar

The JANSEN® HS-20H110 features a drawbar with a hitch, allowing it to be moved comfortably on suitable private property.

The maximum towing speed is 25 km/h.

Important: The log splitter is not approved for road use and therefore must not be towed behind a passenger car on public roads in Germany.

For transport on public roads, the machine can, for example, be loaded onto a suitable trailer using appropriate ramps and secured accordingly.
