Harvester Head EC 761 LF
With power, strength, and outstanding capacity, the Eco Log 761 LF takes on the heaviest jobs. Thanks to the proportional tilting of the feed rollers, more carrying force is generated the larger the stem being processed – all in a head designed according to the Low Friction (LF) concept for maximum productivity and profitability. Combined with high pulling force and a well-protected, robust design, this results in an impressive combination that delivers top performance, reliability, and efficiency in the toughest final fellings.
The Eco Log 761 LF easily handles the largest trees, while also processing smaller final fellings quickly and efficiently thanks to its compact dimensions together with Eco Log Saw Control. With the Eco Log 761 LF, you get a reliable, powerful head with capacity that goes far beyond the ordinary.
FOR THE HEAVIEST JOBS
Strength, power, and stability make the Eco Log 761 LF something truly exceptional, handling even the toughest and most demanding tasks with full productivity and maximum profitability.
TOP PERFORMANCE
The EC 761 LF reaches its absolute peak capacity in stems with a DBH from 20 to 56 cm, while still efficiently handling even larger stems thanks to the LF concept.

Maximizes productivity in every cut
All of Eco Log´s harvester heads have been equipped with Eco Log Saw Control, a patented system that ensures a maximum performance from both machine and harvester head in every cut. The system continuously adapts the guide bar feed, and as a result each cut is optimized irrespective of tree species, stem diameter, chain sharpness or how much power the machine is providing.
A link between the machine and the harvester head ensures that every cut is performed with as high efficiency as possible, where the system continuously optimizes the values regarding to external conditions without the operator needing to change any basic settings manually. It makes no difference if the harvester head is used in mixed forest, in final felling or if you process a spruce with your first cut immediately followed by a birch. Eco Log Saw Control ensures that your felling is fast, smooth and efficient at all times.
Eco Log Saw Control
- The harvester head continuously adapts to current conditions and delivers guide bar pressure and guide bar feed irrespective of tree species.
- Links the saw and machine for optimal performance and efficiency from both harvester head and harvester.
- Minimizing the risk of cutting cracks and generates time savings and efficiency thanks to high cutting speed.
