H412 is a compact, four-wheel-drive head made for small harvesters. It has powerful feed, accurate measuring, and excellent delimbing performance. Its compact size makes it highly maneuverable in dense thinning stands, and its multi-tree-handling equipment is ideal for energy wood harvesting. The mainframe is machined after being welded as one piece for high durability and dimensional accuracy. Three moving delimbing knives, along with one fixed top knife and one fixed back knife, follow the contours of the stem. Maximum felling diameter is 470 mm.
