Eco Log´s new harvester cabin

With the G series, we are proud to present a brand-new harvester cabin, one that has been developed with our full focus on you, the customer. We can offer a modern cab designed for maximum comfort, spaciousness, and ergonomics that also offers operators optimal visibility of the work area at all times. Every detail in the cabins interior, from smart storage solutions and broad charging options to modern palettes and a great sound system, has been carefully selected to make your workday as good as possible.

  • A spacious cabin with plenty of storage space. The swivel seat enables you to easily access and use the rear cab section.
  • The cab boasts windows made of thick safety glass and secure access routes via a brand new platform that allows you to enter and exit your cab via the side-mounted door both easily and safely.
  • The cab uses a brand-new approach for the heating, ventilation and air conditioning (HVAC) system. The system has automatic temperature regulation and has been thoroughly tested in both hot and cold climates.
  • The interior is modern and well thought out. It offers, amongst others, plenty of space, several smart storage possibilities and broad charging options with multiple connections.
  • All G series harvesters are equipped with our Eco Log NexSci control system and we also offera a brand new sound system with integrated subwoofer that is compatible with both Apple CarPlay and Android Auto.
  • The interior of the cabin also has effective sound insulation and comfortable lighting in the shape of integrated LED lamps.
  • Several options for work lightning at the front as well as rear side of the cabin.

Eco Log NexSci

Eco Log NexSci is a flexible and modern control system that takes your operator experience to a whole new level. When developing Eco Log NexSci, we have had you, the operator, foremost in our minds, resulting in a system with a focus on great user-friendliness that enables you to make all the necessary selections and settings easily and intuitively.

Eco Log NexSci also gathers all machine functions on a single display. For you as an operator, this provides an excellent overview of both bucking and machine data while working, with all functions presented in a clear, stylish, and modern interface.

Powerful crane

Experience the power of Eco Log’s harvester crane

Thanks to Eco Log’s proprietary crane, the harvesters deliver unmatched power and productivity. The crane is specially developed for harvesters and can easily maneuver and lift the harvester head even when used at long reaches and in steep terrain.

Combined with the pendulum arms on the 500 series harvesters, the crane enables the machine to work with high power and efficiency even in steep and hilly terrain as the wheels are adapted to the terrain so as to keep both the machine and the crane optimally positioned.

  • Eco Log’s proprietary crane is available in five different versions – 235, 250, 270, 280 and 300.
  • The powerful crane, together with the harvester’s pendulum arms, maximizes machine productivity.
  • Thanks to its power, the crane is ideally suited to multi-tree handling.
  • The movement pattern allows snags to be felled safely and securely and the crane remains powerful even at great heights.

  • Eco Log harvesters gives its operator full control in any situation as the machine adapts to the terrain due to the pendulum arms. By raising, lowering, or tilting the machine by means of the pendulum arms, the harvester can easily navigate all types
    of terrain.
  • The harvesters are equipped with engines from Volvo Penta, characterized by their low fuel consumption, responsiveness, and long service interval.
  • Servicing is quick and convenient thanks to the all parts of the harvester being easily accessible and the ability to lower the machine to the optimum working height.
  • The crane and the harvester head are easily lifted and operated with high torque and efficiency even at long reaches and in difficult terrain. This is a major advantage, for example, when thinning or harvesting logging residue.
  • Optimized interaction between the hydraulic system and the diesel engine means that the machine always works at high capacity and with great efficiency.
