AFM 75 harvester head


AFM 75 is a strong, reliable and highly productive harvester head for big wood which can work on both wheeled and tracked machines. It has been developed with close attention to customers’ needs and incorporates the best features of AFM heads. AFM 75 means an optimal combination between capacity, weight, feeding power and force and is an efficient tool for clearcuttings, big thinnings and processing operations. Four movable knives on AFM 75 allow smooth and accurate delimbing even of big trees with heavy branches. The stem is constantly centered in the head with three feeding rollers ensuring precise length and diameter measuring. Proportional adjustments of pressures on rollers and knives according to the stem diameter increase considerably the effectiveness of feeding and delimbing. The shape of knives on AFM 75 allows easy working from pile or in wind stormed areas. AFM 75 can work with a variety of different measuring systems and can be easily adapted to any type of base machine. The AFM 75 is perfectly suited for 20-30 tons excavators, wheeled and tracked harvesters.
