Abstract: The object of the invention is a colour-marking arrangement in the cutting flange of timber harvester. The arrangement includes a flange (1) with a carrier (6, 7), an adapted pipework (4), a series of channels (12) formed to the carrier (6, 7) and connected to the pipework (4), which ends opposite to the connector connections (11). The pipework (4) is formed from a separate component (4, 9, 10) from the flange (1), and is adapted to be set into the flange (1) in a space (3) reserved for it in the same way as the flange (1) is set into the carrier (6, 7) by means of a longitudinal movement.

Abstract: A timber harvester disclosed includes a frame (1), two feed tracks (5) jointed opposite one another, a front stripping blade (20), and a rear stripping blade (16). A frame (4) of the feed track (5) is carried on jointed trapezoid arms (2,3). A rear stripping blade (16) is located on the frame (4) of one of the feed tracks (5) and is jointed essentially on the line of the compressive force between the feed track (5) and a tree (7), when seen from the direction of the timber feed.

Abstract: The present invention provides a feeder apparatus for timber harvesters, said apparatus being intended to pull the log in for trimming and preferably featuring a three strand roller chain rotating around a turning wheel and a cog wheel with log grabbing members attached to the outer plates to the roller links of the roller chain. It is the intention of the present invention to realize a track-operated feeder apparatus simpler yet sturdier than conventional designs. In a feeder apparatus in accordance with invention, the chain is powered by a cog wheel driving the center strand of roller links, and all strands of roller links are supported essentially for a grab length sufficient to provide a firm contact to the logs by rolling beds supporting the rollers.

Abstract: Suspension device for suspending a felling processor (1) to be installed at the end of the jib (13) of a loader by means of an upper joint (12, 18, 17), which suspension device includes a turning motor (11) to turn the frame (6,9) of the suspension device and with it the harvester (1), an operating device e.g. a hydraulic cylinder (7) to turn the harvester to the desired vertical or horizontal position and in which the suspension of the harvester from the frame (6, 9) of the suspension device is realized by means of a transverse joint (4) and the aforementioned operating device is secured between the frame (6, 9) of the suspension device and the frame of the harvester (1). By means of the suspension device in accordance with the invention an attempt is made to achieve a short length of the deivce and nevertheless to achieve a sufficient vertical rise.
