EC 561 LF

The Eco Log 561 LF is a high-production all-round harvester head, designed to handle the various tasks within forestry efficiently – everything from thinning low-grade timber to basic final felling.

The low-friction concept (LF) ensures maximum productivity, durability and profitability thanks to the fact that it minimizes friction, wear, and maintenance requirements.


The harvester head’s compact dimensions, combined with perfect delimbing down to 30 mm, allow the thinning of low-grade timber to be carried out quickly and efficiently with the highest quality. Three smart patents – LogHold, proportionally angled feed rollers and Eco Log Saw Control – produce a harvester head boasting impressive stem holding, strength and maximum production.
