摘要:
A guide (23) supports a pole (22) by clamping a tree. (27) Guide (23) is a separate device which is comprised of a frame (24 25) which houses a tree clamp (31) and a pole clamp. (32) The use of guide (23) greatly extends the reach of a cutter. (21) Multiple poles (22) and guides (23) are added to reach a pre-determined cutting height. Guide (23) provides a stable elevated platform where a pivot point (71) is established. Leverage is thereby provided for positioning and moving cutter. (21) Trimming begins by activating cutter (21) and releasing pole clamp (32) allowing cutter (21) to engage with branches. (34) Additionally, branches (34) are also trimmed utilizing motor driven wheels (59) which provide rotation of guide, (23) pole (22) and cutter (21) around the perimeter of tree. (27)
