This hedge trimmer will trim branches up to about the diameter of your pinky. Anything larger than that requires the use of a chain saw. Hedge trimmers must be used on flat ground only (not up in trees or ladders) and are not to be used on dirt. The user of this item must come in to receive full use and safety instructions. This item is only available during our open hours. No overnight rentals on this item due to insurance liability. This item requires a standard 110v power supply.
