The power of the PONSSE harvester heads 550, 650 and 750 lies in their versatility. Each harvester head can be built according to customer wishes, conditions and purpose of use. All PONSSE 550, 650 and 750 series harvester heads can be built as a 4WD option by installing a second pair of feed rollers instead of rear knives; colour marking and stump treatment systems can also be installed on all models. If necessary, PONSSE 550-750 harvester heads can be equipped with a topping saw. Thanks to the modular construction, the head is always customized according to needs, timber species, conditions and purpose.
