A timber harvester includes a scissors-like frame component including opposing segments with a common joint, a fork-shaped tilting device, a saw device installed at the rear end of the harvester, opposing tree feed devices installed on both of the aforementioned segments, articulated lower delimbing blades driven by an operating device, and at least one upper delimbing blade supported by at least one segment. The upper delimbing blade is secured, with the aid of the first and second sliding members from both segments so that the first sliding members include, in both segments, a linear guide that lies generally in the direction of the segment itself, and slides adapted to the linear guide in the upper delimbing blade. The second sliding members including at least one joint in the upper delimbing blade of the nearest slide, and at least one curved guide in one segment, the second sliding members being arranged to prevent the twisting of the upper delimbing blade.
