Abstract

The invention concerns an arrangement for felling, trimming and cutting trees, which arrangement comprises a frame 1, saws for felling and cutting, drive means 3, 4 such as feed wheels, drive cylinders or conveyors for transporting the tree through the arrangement, which drive means are arranged to rotate about axes of rotation 16, 17, and an upper cutting blade 5, front cutting blades 6, 7 and rear cutting blades 8, 9 for trimming the tree, which movable cutting blades are arrranged to pivot about axes of rotation 19, 20 and 16, 17, respectively. To be able to trim trees with a large range of diameters, but despite this have a small and compact arrangement, the axes 19, 20 for the front blades 6, 7 and the rear blades 8, 9 are moved in relation to each other so that the axis 16, 17 for the rear blade lies above the centre line of the upper blade 5, which axis is also arranged in line with the axis 16, 17 for the movable drive means 3, 4. <IMAGE>
