The GSA feller buncher is designed for demanding forestry work where trees must be felled and processed quickly and safely. Suitable for excavators and telescopic handlers, it is available in two models capable of cutting trunks from 250 to 650 millimetres in diameter, making it ideal for large-scale timber operations.
The machine performs the felling directly from the cutting head. Once the cut is made, the system immediately positions the trunk horizontally, allowing fast, controlled handling and efficient processing. The robust frame is built from wear-resistant steel and powered by a hydraulic motor for strong, consistent performance.
The hydraulic setup requires two double-acting lines and one free-flow return to tank. The cutting unit features a hydraulic chainsaw equipped with a rapid mechanical chain tensioner and automatic bar lubrication, ensuring smooth cutting cycles and reduced downtime.
Safety is enhanced through a lock valve on the hydraulic cylinder, which keeps the grapple securely closed even if hydraulic pressure drops. This ensures safe handling during cutting, lifting, and tree placement.
Each model is available with a full turnkey kit that includes a mounting bracket specific to your machine and a dedicated hose kit, allowing fast installation and immediate operation.
