From

0

AFM 50 L has just one pair of movable knives and a shorter base, allowing easy working with curved trees and hardwood species. For its weight, the AFM 50 L has great capacity. The reliable hydraulics of the AFM 50 L allows the use of a higher pressure level together with the non-sliding feeding system. The high-speed saw unit is equipped with handy hydraulic chain tensioning, which keeps the chain firmly tensioned during felling and cross-cutting. Its extremely strong frame makes the AFM 45 L reliable, not just on wheel-based machines, but also on track-based harvesters. A suitable base machine for AFM 50 L harvester head is a mid-sized forest machine or a 12- to 16-ton excavator.
