ABSTRACT OF THE DISCLOSURE This invention relates to a tree pruning machine which comprises a frame in a cutting unit having a first member stood on a body having wheels elevating vertically, and a second member projected from the top of the first member forwardly in an ascent gradient and formed with a recess at the front side, the first member having drive wheels mounted on the lower portion thereof and driven by an engine for driving the drive wheels, and a saw chain rotated by the engine through the drive wheels along the frame formed of the first and second members for cutting a branch of a standing tree. Further, there is also provided a tree pruning machine in which a branch sensing member is telescopically provided in the lengthwise direction of the second member, the front of the sensing member is projected forwardly of the second member to temporarily stop the drive of the pruning machine toward the upward direction of the standing tree. The sensing member of the pruning machine can reliably sense the branch to be contacted with the top of the cutting unit and the sensing member may not disturb the pruning machine to climb the standing tree. Thus, the pruning machine can climb the standing tree without fail even when the cutting unit makes contact with the branch of the tree.
