HydroCombi 20 chassis

Full-length log splitter

A full-length log splitter is a success story The classic that never goes out of fashion: The beginnings date back to the 1980s, when the first hydraulic metre-long timber splitters came onto the market - a minor revolution at the time. Even today, the HydroCombi makes working with firewood considerably easier. There are now 283 possible combinations to choose from – ranging from 13 to 26 tonnes of splitting force, from petrol to hybrid powertrains, and featuring many extras such as a winch. And best of all, You can rely on the HydroCombi – for decades to come: Even today, the very first POSCH log splitters from the 1980s and 1990s are still in use! You can never have enough of some greens: More than 80,000 models sold speak for themselves! The metre-long timber splitter is not only extremely popular, but also a pioneer in terms of safety - thanks to the two-hand control and the newly revised Fixomatic system, which holds and splits both logs and billets safely and efficiently.

Floor grate with functional design

In combination with the Fixomatic System 2.0, the special, further developed shape of the floor grid provides an optimum base and secure hold for your log. It ensures greater stability and, consequently, greater safety and comfort when loading or splitting wood. The floor grating can be folded up for easy cleaning; all you need to do is loosen a single screw.

Back-friendly and safe lifting of the log with the log lifting device!

The HydroCombi brings heavy logs into the right position almost by itself. The standard mechanical log lifting device raises the logs in a convenient and back-friendly manner. The wood flap attached to it prevents the trunk from slipping or falling over whilst being positioned. To make it easier to roll the log onto the log lifting device, it can be folded away in a single movement. The cushioned catch area acts as an anti-slip pad and impact protection, absorbing the energy of the split wood and minimising kickback. This keeps the logs in position for further processing and prevents them from falling towards the operator. Optional rope winches make your work even easier.

Work smarter, not harder: Damped safety guard with impact protection!

The new safety bar prevents the split wood from falling over and also serves as a handy temporary shelf. Thanks to innovative technology, bent and damaged protective bars are a thing of the past. Under heavy loads, the new safety bar swings downwards and backwards, providing additional energy-absorbing impact protection that minimises the rebound of the logs. A practical sappie holder is also integrated. In the event that the winch is subject to retrofitting, the protective bar can easily be folded down to allow for this. This increases the working area for operating the winch.

Fixomatic 2.0

The two-part splitting blade (Fixomatic system) securely holds the wood in place for the splitting process – without the need for any fiddly holding. The lower wedge also fixes thin or angled wood without any problems, and the wedge is conveniently released at operating height. Incorporated, patented grooves on this part of the wedge make it easier to split fibrous or soft wood, prevent slipping and interlock. In addition, the tried-and-tested wood holding tip on the wedge guide ensures an even better grip. As soon as the splitting process is triggered, the upper wedge moves towards the fixed wedge holder and pushes the splitting wedge through the wood. Grooves in the upper part of the wedge guarantee precise guidance during the splitting process and thus increase the operator's safety.

Ready for action round the clock!

The mobile machine is flexible and adapts to a variety of operating conditions. It is ideal for transport – for example, for machine pools – and can be easily moved from the working position to the transport position.

What speaks for the HydroCombi with chassis

Split files fast with the lift limit!

Avoid unnecessary empty runs when splitting and save time! Thanks to the stroke limiter, the return path is reduced to the required log height, so that the HydroCombi is ready for use more quickly. Optimise your work efficiency by simply adjusting the splitting stroke to the desired log length at a comfortable operating height: Loosen the locking screw and adjust the stroke using the markings on the stop bar.

Innovative riving wedge

The splitting wedge, which slopes forwards as standard, prevents the split material from being pushed towards the operator and at the same time reduces the force required for splitting. The riving wedge consists of two parts: To prevent the wood from falling towards the operator during the splitting process, rollers with grooves are incorporated into the upper splitting wedge, and grooves are integrated into the lower part of the splitting blade. These patented innovations ensure precise guidance, minimise slippage of the wood and thus protect the operator from falling logs.

Sappie holder

Park your Sappie conveniently on the outside of the machine: Whether on the log lifting device or on the safety bar – the storage option is suitable for both right- and left-handers, and the Sappie is easily accessible from the operator’s station.

Safety shut-off damper

For increased safety: If a piece of wood gets between the splitting wedge and the safety shut-off flap during the return travel, it stops the return travel of the splitting wedge.

Large when in use, compact for storage and transport.

Once the work is done, simply actuate the hand-operated cable winch attached to the chassis drawbar to swing the HydroCombi back into the transport position. This allows the machine to be stored in a compact manner.

Maximum flexibility and comfort: Optional electric motor for your HydroCombi

Enjoy even greater comfort alongside the powerful petrol engine drive. For added flexibility, we offer the option – at an additional cost – to include a 5.5 kW electric motor (3 x 400 V, 50 Hz, S6, CEE 16 A) and a direct-start motor protection switch with a phase inverter and rotation field detection as part of the standard equipment. This drive is perfectly matched to your HydroCombi and is compatible with item numbers M6203PSAR and M6248PSAR – for more efficient use and optimised workflows.

Hydraulic log lifting device

The optional hydraulic log lifting device replaces the standard mechanical version and effortlessly lifts the log into the splitting position – without any physical effort whatsoever. The wood flap attached to it prevents the trunk from slipping or falling over whilst being positioned. To make it easier to roll the trunk onto the hydraulic log lifting device, the device can be folded away in a single simple step. The cushioned catch area acts as an anti-slip pad and impact protection, absorbing the energy of the split wood and minimising kickback. This ensures that the logs remain securely in place for further processing and cannot fall towards the operator. Equipped with its own oil circuit and an integrated valve, it provides a precise and efficient control system. The lifting arm of the hydraulic log lifting device can be adjusted to any height and can be actuated at any time – regardless of the splitting process. This elevates both working comfort and safety.
