ABSTRACT OF THE DISCLOSURE This invention relates to a tree pruning machine having an elevating body detachably set to a standing tree, and a rotary device having a cutting unit detachably mounted on the body to rotate around the periphery of the body, comprising a linkage mechanism having at least three set of wheel units each including a plurality of upper and lower wheels for elevating vertically on the tree and movably mounted radially of the tree on the body, an interlocking mechanism for interlocking the wheel units to each other for moving the wheel units always in the equal distance radially of the tree, and a pressure equalizing mechanism having springs for contacting the wheels of the respective wheel units under the equal pressure with the surface of the tree. Thus, even if the tree T varies in the diameter, the pruning machine A cuts the branch t at the root while stably and reliably climbing the tree T always at the center of the tree T, and automatically descends the tree T when finishing the tree pruning work.
