摘要： A powered apparatus having an elongate pole with a tool at a proximal region and a drive for operating the tool. A first operating component is repositionable between first and second positions to change a state of the drive. A second operating component is repositionable between: a) a locked position; and b) a released position wherein the first operating component can be changed from the first position into the second position. A handle assembly has a gripping portion with an extent that can be grasped by the user's one hand at a plurality of different locations along the extent of the gripping portion to control the operating components, including at a first location in a manner wherein with the elongate pole vertically oriented, a majority of a vertical weight force component of the apparatus is directed generally parallel to the length of a user's forearm below the user's one hand.
