The H8 harvester head has a completely upgraded new structure.
The Ponsse H8 harvester head has a powerful feed, firm grip and solid yet agile frame. Active Speed is available for the harvester head as a new feature, giving the harvester head a superior performance. With Active Speed, the harvester head’s operating speed can be adjusted based on the tree species and stem diameter. Equipped with this new function, working with the H8 harvester head is smooth and productive, no matter what the tree diameter is.
The new harvester head can be mounted on the Ponsse Ergo and Bear, the strongest harvesters in Ponsse’s product range. The saw box area is even wider, making the harvester head a good choice for trees with a high butt diameter. The harvester head’s structure has been designed for easy maintenance, and the frame has been built to be even more durable. A powerful feed, combined with a geometry that firmly supports larger stems on feed rollers, provides high productivity and fuel economy. The automatic features of the Opti control system, developed and built by Ponsse, control the feed speed and saw movement, according to the tree diameter, and ensure fast and precise sawing. Source
