Abstract

The mechanism is used for rotating a tree-felling implement rotatably mounted with a pivot to the distal end of the boom of a logging vehicle. The mechanism, the tree-felling implement, the boom and the logging vehicle form a tree-felling machine controlled by an operator and used on logging sites. The mechanism comprises a pinion coaxial with the implement pivot and fixed in rotation with reference to the distal end of the boom. An arc-shaped rack is rotatably mounted on the frame of the implement by a rack pivot in spaced relationship with the pinion. The rack is in mesh with the pinion and hydraulic actuators are provided on the frame of the implement for swaying the rack and thereby rotating the implement with reference to the boom. Such mechanism is capable of rotating the tree-felling implement with reference to the boom plane in both directions and according to a much wider range angle than the prior art mechanisms.
