Abstract
A powered apparatus having an elongate pole, a drive at a proximal region of the elongate pole and operable to rotate a first component on the drive, a tool at a distal region of the elongate pole with a second component that is rotatable to operate the tool, and a power transmission assembly for transmitting a drive force generated by rotation of the first component to the second component to thereby operate the tool. The power transmission assembly has a flexible drive link with a flexible length located between the drive and at least one other substantially inflexible drive part that is downstream of the drive link. The flexible length of the flexible drive link is greater than four (4) inches.
