2016 is the year when Eco Log’s newest generation of 550, 560, 580 and 590 harvesters will be launched with Volvo Penta D8 engines installed, ranging in power from 218 to 320 hp. Characterized by their high performance, reliability, fuel efficiency, and low emission levels, Volvo Penta diesel engines are built to be versatile. The engines are developed to satisfy forestry application with their low weight, compact designs, and easy installation, making them perfect to power the new Eco Log harvester generation.

It is important to mention that Eco Log and MTU (Mercedes) remain partners. The reliability and efficiency of MTU engines, notably the 926 LA, have undoubtedly contributed to the success of Eco Log machines over the past years. Therefore, the existing D-series forwarder and 688 continue to be equipped with Mercedes Engines.  

The choice of Volvo Penta Engines for harvesters has been motivated by 3 main reasons: Proximity, Flexibility and After-sales.

i. As simple as it sounds, Volvo is a Swedish heritage and Eco Log, which is based in Söderhamn on Sweden’s east coast, has over the past few years highly focused on the value of using local components. Suppliers with a close geographic location enable both better support and closer partnership.

ii. One and the same engine block can fulfill several standards, for example with either Stage IIIA or Stage IV-compliance. This smart flexibility contributes to the efficiency of Eco Log production by providing the ability to use the same base machine frames while simultaneously fulfilling the various emission requirements worldwide. 

iii. International sales have expanded over the past two years and Eco Log is now represented on four continents. A strong global network is required to guarantee maximum uptime, reliable service and peace of mind for Eco Log customers.

The new Eco Log 550, 560, 580 and 590 harvesters are dressed with the latest Eco Log colors and will of course remain equipped with innovative pendulum arms. Their impressive ability to tilt 25° sideways and a pitch angle of 17° to the front or rear allows them to easily maneuver in hilly environments. Eco Log equips, as standard, the new 550, 560, 580 and 590 with five pumps; two for the transmission, two implement pumps (one for the crane and one to operate the harvester head) and one so called “recirculation pump” which together with the new vertically oriented coolers optimizes the cooling capacity of the harvester where and/or whenever the machine operates. The Volvo Penta engine provides power to these pumps, running at a low rpm, and can easily handle all working conditions without overloading the engine. Among other new features, the cab is now able to rotate 350° further decreasing the frequency of machine movement versus competitors and thereby saving additional fuel costs even beyond those provided by the already efficient Volvo Penta engines. 

Note that the 570 has been removed from the harvester range to the benefit of the 550. This unique four wheeler is now powered by 218 hp and is equipped with a larger crane (the Eco Log crane 250 [255 kN], previously installed on 570D).
