Resonant frequency operation of a reciprocating sickle (28) of a mowing device is achieved by connecting a torsion bar (97) to its actuating lever (82). The torsion bar (97) spring rate is such that when installed in a sickle and drive system, the resonant frequency of the sickle and its drive falls within the range of frequencies at which the sickle is reciprocated during crop cutting operations.
