Eco Log: First in the World with Bosch Rexroth's New Valve Platform, RM Global
With its new 688G harvester, Eco Log becomes the first machine manufacturer to bring Bosch Rexroth's groundbreaking RM Global valve platform all the way to the field. The result is a new level of precision, efficiency, and a deepened technical collaboration.
Premium Machines for the Future of Forestry
Eco Log develops and manufactures high-performance harvesters and forwarders for sustainable, efficient forestry. With roots in Skogsjan and Caterpillar, the company is based in Söderhamn, Sweden—in the same factory where forestry machines have been produced since 1965. The Eco Log brand was established in 2004 and has since grown into a recognized player with a global presence. The company has strong markets in Scandinavia and Central Europe and is now also represented with growing market shares in Canada, the USA, and South America.
Today, they are known for their wide range of harvesters, forwarders, options, and accessories—all distinguished by their strength, reliability, and cost-effectiveness. With a strong development team and a focus on adaptability in demanding terrain, Eco Log is a player that collaborates closely with its suppliers to create machines in the premium segment. "The forest is a vital resource that affects us all, and our focus is on developing a reliable and efficient forestry machine that gives our contractors the right conditions for both profitability and long-term sustainable forestry," says Emil Forsblom, Head of Development at Eco Log.
A Proven Collaboration That Has Grown Over Time
The collaboration between Eco Log and Bosch Rexroth has been ongoing for many years. Rexroth has long been a key system partner, supplying pumps, hydraulic motors, control systems, and sensors. During the development of the new harvester, this collaboration was taken to a new level. "We have always had confidence in Rexroth, but in this project, we have truly worked together as one team," says Emil. "It's not just about components, but about accessibility, technical understanding, and commitment. We were given direct contact with the designers in Germany, and that has really made a difference."

New Modular Valve with Precision and Energy Efficiency
When development of Eco Log's new 688G harvester began, the valve platform was a key component. The choice fell on Bosch Rexroth's RM Global—a completely new generation of modular load-sensing (LS) valves that combines high precision, flexibility, and energy efficiency. The 688G is the first machine in the world to be equipped with the new valve and has delivered results that have exceeded expectations, with improved crane control, reduced leakage, quieter operation, and a smoother feel—without compromise in extreme temperatures.
RM Global consists of the modular RM10 and RM15 valves, which are combined via a uniform flange design. This makes it easy to adapt the valve to different machine requirements without increasing installation space or costs. The new-generation valve features flow-optimized channels and supports a working pressure of up to 420 bar. This means the dimensions of other components can be reduced—saving weight, energy, and money.

For Emil and the team at Eco Log, this close technical collaboration was decisive. Bosch Rexroth was involved every step of the way—from the initial concepts through the entire project stage to a tested and finished product. "Having direct contact with the designers and engineers behind the product—not just the sales side—has allowed us to work efficiently and make the right decisions along the way," says Emil. Launching a new technology platform is a challenge, but this case is proof of what is possible when product development is done in partnership.
From Testing to Results—Through Close Collaboration
Eco Log began testing RM Global in the spring of 2024, with Bosch Rexroth's teams from both Sweden and Germany on site. The testing period focused on precision, replenishing performance, and integration into Eco Log's compact machine designs. "Once on site, very little work was required from our side, thanks to our thorough groundwork," says Emil. "We had spent a lot of time on preliminary studies, defining our needs, and preparing potential actions if something didn't work. The machine was set up, Bosch installed the sensors, and then we could start measuring immediately. Furthermore, having direct contact with the designers from the factory makes a huge difference. It's not just about technology—it creates a shared commitment and a true collaboration."
An Upgraded Hydraulic System
In addition to the new RM Global valve, Eco Log's 688G is equipped with a fully upgraded hydraulic system, in which Bosch Rexroth played a central role as the system supplier. The new system includes motors, pumps, valves, and electronics—all carefully integrated to create a powerful, efficient, and reliable machine platform. "We've received a very positive reception. The new harvester builds on something that was already popular, but now with even better performance," Emil explains.

Series Production to Start in 2026
The new harvester will be launched in September 2025 and showcased on a demo tour across Europe. Market interest is already high, and the machine is expected to enter series production in 2026. Emil is optimistic about the future, both for the machine and the collaboration with Bosch Rexroth.

"We are very pleased. As a medium-sized company, it is important for us to build strong collaborations with dedicated suppliers. In modern development, where technology advances at a furious pace, it is crucial to work with competent partners—both to maintain a high level of innovation and to achieve good cost-effectiveness. For us, development is also about risk management—choosing the right products and the right partnerships. It's about betting on sure things. Bosch Rexroth has both the technology and the personal commitment. That makes all the difference. It should feel natural and easy to just pick up the phone and call each other," Emil concludes.
Why Eco Log Chose RM Global for Its New Harvester
Technical Performance That Met High Demands
During testing, RM Global demonstrated that it delivered the high precision, control, and responsiveness required for Eco Log's crane control. The valve was perceived as very responsive, leak-free, and quiet—important characteristics for a harvester used in tough conditions and during long work shifts.
Flexible Integration Without Compromise
The modular construction and uniform flange design made it easy to integrate RM Global into the machine's compact layout. Furthermore, Eco Log had the opportunity to make requests during the project, which Bosch Rexroth could incorporate into the development of RM Global.
Close Technical Collaboration All the Way
Eco Log highlights the direct collaboration with Rexroth's development teams—both in Sweden and Germany—as a decisive success factor. The joint testing phase and the ability to influence details in the system solution made Bosch Rexroth more than just a supplier—they became a true development partner.
