Proven performance. AFM 400s AFM 400S Stroke is especially designed for forest operations made with small base machines. Compared to same weight harvester heads the 400s has a lot of delimbing power. AFM 400S has a measuring device that makes the production highly efficient. Measuring system can be programmed for various pre-selected lengths. In addition any length can be chosen at any time. As optional equipment the diameter of the log can also be measured.The various operating handles are available and they have been designed for professional use. The head has an automatic stroke and the tree can be delimbed with a one-button function. The stroke will stop at the pre-selected length for the log to be cut. AFM Stroke head is suitable also for base machines with low hydraulic power. Most common farm tractors have enough hydraulic power to operate 400S. Also good choice would be an 6-8 ton excavator.
