Base machine: PONSSE Bear and track based machine over 20 tons

PONSSE H8HD is a tough-built harvester head with high power and excellent geometry for the most demanding logging operations. It is designed for the hard use in tracked base machines, featuring a heavy-duty frame structure and efficient hydraulic system to ensure high reliability and performance.

PONSSE H8HD is a heavy-duty harvester head for felling and processing of hardwood and softwood in hard conditions. Strong grip, powerful feeding and fast sawing are packed in a robust and reliable package that can be fitted into various tracked carriers. Reinforced frame and tilt arm give robustness needed in tough operations. Wide feed roller geometry supports even the large stems with feed rollers instead of delimbing blades. This allows using lower pressure on knives, improving fuel economy and feeding speed as well as measuring accuracy. Optimal tilt pivot geometry minimizes the upwards torque of the head, giving smoother feeding and better grip of the tree.

PONSSE Opti control system is designed specifically for PONSSE harvester heads. All adjustments and settings work perfectly together with the head, offering easy but versatile functions to perfectly fit the base machine and work requirements. PONSSE systems offer mobile follow-up of production and working with either manual or automatic data transfer.

The PONSSE H8HD is available with a top saw for processing curvy trees with multiple branches. Processing delimbing knives are longer than standard knives for picking logs more easily from a pile.
