Hedge shear

Abstract

A motor-driven hedge shear has a housing, a pair of hedge shear cutters extending in a longitudinal direction outwardly of the housing, means for reciprocatingly driving the hedge shear cutters in opposite directions and including a motor shaft, a coulisse transmission provided between the means and the hedge shear cutters, cutter holders provided for supporting the hedge shear cutters and having coulisse ears, the coulisse transmission including toothed gears provided with crank pins engaging in the coulisse ears, a central shaft supporting the toothed gears and having ends rotatably supported in the housing. Two of the toothed gears of the coulisse transmission are arranged on the central shaft so as to be axially spaced from one another, and have facing sides provided with crank pins formed as eccentrically arranged circular discs. The coulisse ears of the cutter holders surround and slidingly guide the crank pins, each of the crank pins having a first opening surrounding the central shaft and being connected with an adjoining one of the toothed gears so as to be rotated by the latter.
