Abstract

A delimber (10) for removing secondary limbs from a primary limb of a tree Comprises an arm (12) arranged to extend around the primary limb. The arm is provided with cutter segments (18) oriented to cut the secondary limbs from the primary limb of the tree. The delimber also comprises a means (50, 52, 54) for moving the arm at least partly along the length of the primary limb. In use, the arm is extended around the primary limb of the tree and is then moved along the length of the primary limb, thereby cutting secondary limbs from the primary limb.
