Abstract

A lopper used to perform lopping, pruning and similar operations includes a lopping head having a spring-biased blade cooperating with a jaw, a drive mechanism connected to the lopping head and an elongate housing connected to the drive mechanism. The drive mechanism includes a first and a second mating portion selectively rotatable with respect to one another about an axis permitting positioning of the lopping head relative to the elongate housing, a first wheel rotatable about the axis, a second wheel rotatable about the axis and coupled to the blade by a head line, and a driving line arrangement comprising a driving line arranged to rotate the second wheel and the first wheel together when the driving line is drawn and to keep the second wheel stationary when the lopping head is positioned relative to the elongate housing.
