Abstract
A cutting and/or sawing unit for timber handling purposes and adapted to be mounted on the free end of a working arm or jib of an off-road vehicle. The unit includes a saw (4) rotatably mounted on a motor stand (1) and knives (6) which project out from a hub part (5) of the saw. The knives are intended to coact with a toothed device (7) on the motor stand (1), to obtain a cutting action in addition to a sawing action. Mounted on the upper side or top plate (11) of the motor stand is a gripping device (2). The motor stand (1) is pivotally suspended on a preferably horizontal shaft (13) journalled in a suspension link (14). This arrangement enables the saw (4) or the griping device (2) to be brought to a working position relative to the surface of the ground, by rotating the motor stand (1).
