Abstract
A control lever is provided for operating a working machine. The control lever includes a base portion intended to be mounted to a working machine, and a top portion which is pivotally connected to the base portion for pivoting about a geometrical X-axis. The top portion is further adapted to be gripped and pivoted by an operator in order to operate the working machine, and the top portion has an outer gripping surface for receiving the palm of the hand of an operator. At least a part of the gripping surface is arranged adjacent to the geometrical X-axis in such a way that the geometrical X-axis is situated inside the hand and adjacent to the center part of the palm of the operator when the top portion is properly gripped by the operator.
