The Usewood Combi Master delivers everything a forest owner needs in one machine. From brushwood cutting to the first thinning, the Usewood Combi Master can act as a harvester, forwarder and brushwood cutting machine.

Combi Master combination machine

More than just a forwarder with a harvesting head

Individual forest owners are able to purchase only one machine for their needs, thus reducing young forest management costs. As all other Usewood machines, the Usewood Combi Master can also be transported with a trailer thanks to it’s weight of less than 3000 kg. Low ground pressure and fuel consumption, electrical controls and a comfortable safety cabin with heating, air conditioning and radio are our everyday standards.

Loading space

Since forwarding, harvesting and brushwood cutting all have very different requirements for a machine, we designed the Usewood Combi Master to be able to carry out all of these functions without compromises. The machine has a hydraulic extension in it’s loading space allowing shortening of the loading space, increasing operability and decreasing the steering radius when harvesting and cutting brushwood. This makes it possible to leave narrower harvesting tracks in the forest, minimizing the environmental impact. On the other hand, the operator can expand the loading space while forwarding with the single press of a button from his/her cabin. The Usewood Combi Master can transport 4 meter logs without any extra components.

Operator comfort is our priority. Easy-to-use, flexible electronic controls are one thing, but on top of that the FOPS & ROPS tested rotating safety cabin gives an unparalleled driving experience in a small forest machine. When the whole cabin rotates between driving and loading positions, the operator always has the best possible visibility and operability regardless of the driving direction. The windows are made of polycarbonate, ensuring the safety of the operator when harvesting. Even if the harvester head’s saw chain broke, the operator would not be in danger inside the cabin. Heating and 3 kW air conditioning ensures that the temperature is always optimal for comfortable working.

Taking it’s power from a trustworthy 4-cylinder Kubota V1505T turbo diesel engine, the Usewood Combi Master has enough power for delimbing trees with strong branches while minimizing fuel consumption during the working day. With the aid of our own RECS control system, the full power of the 44-horsepower engine can be utilized with minimal power losses. For example, in a tight spot the control system can focus all power on the task by only using secondary features, such as the air conditioning’s 3 kW compressor, when the operator is not requesting full power from the engine.

We are known for the RECS control system that we have developed ourselves. A small machine has limited resources which have to be used with care in order to guarantee the best possible efficiency. The control system provides not only a 7″ RGB LED touchscreen display for monitoring the condition of the machine but also the possibility for the operator to configure all the machine parameters to fit his/her own driving style. Four different operators can save their own parameters on the machine, making it easy to share a machine with other drivers. The RECS control system also has digital fuses, making it able to detect open and short circuits automatically and warn the user on the touchscreen display of the malfunction and it’s location in the system. This makes electrical problems easy to solve. A good electrical control system provides a superior driving experience and reliability compared to traditional mechanical controls.

The Usewood Combi Master uses the same hydraulics as all our other machines. With Bosch Rexroth’s LUDV load sensing valves and a 0-130 l variable displacement pump operating the machine is easy and efficient. The large hydraulic pump provides enough oil flow for moving the crane fast from side to side when forwarding or feeding the tree’s with enough speed when harvesting. The hydraulic transmission makes forwarding the logs out of the forest a pleasure, while at the same time providing a 12 km/h top speed. Thanks to the RECS control system, we have optimized the hydraulic system to be as simple as possible. Unlike traditional forestry machines with separate hydraulics for driving and crane operation, we combined these so that the same open-loop hydraulic system takes care of both driving and crane operation. This simplifies the whole system and reduces the number of easy-to-break components, also reducing the need for spare parts.
