The DEVELON/DOOSAN Feller, an intelligent and efficient forestry equipment, is designed for 12-15 ton machines. It adopts a precision circuit board for control, allowing free setting of logging lengths and ensuring accurate segmental cutting. With high intelligence, it comes with automatic feeding, automatic branch removal, and automatic chain saw tensioning—reducing manual intervention and enhancing work stability. This feller adapts to multi-diameter logging tasks, with a maximum logging diameter of 360mm, and its intelligent control system minimizes tree damage during operation. Meanwhile, it achieves optimal matching with the host machine, guaranteeing high logging efficiency while keeping fuel consumption low, effectively helping users cut operational costs.
